And a notifying unit for notifying the first transport vehicle of delay information when detected.
　これによれば、物流倉庫に到着予定の第一搬送車両からの第一到着予定情報に基づく準備計画が遅延している場合に、第一搬送車両に対して遅延情報を通知することで、第一搬送車両の運転手に、物流倉庫の第一搬送車両に対する準備が遅延していることを知らせることができる。これにより、例えば、運転手に、準備計画からの準備の遅延を考慮して物流倉庫に到着するまでの時間を有効に使うことを促すことができる。よって、物流倉庫において搬送車両が待機する時間を低減することができ、物流倉庫において待機する搬送車両の数を低減することができる。 According to this, when the preparation plan based on the first arrival schedule information from the first delivery vehicle scheduled to arrive at the distribution warehouse is delayed, the first delivery vehicle is notified of the delay information, The driver of one transfer vehicle can be notified that preparation for the first transfer vehicle in the distribution warehouse is delayed. Thereby, for example, it is possible to urge the driver to effectively use the time required to arrive at the distribution warehouse in consideration of the delay in preparation from the preparation plan. Therefore, it is possible to reduce the waiting time of the transport vehicles in the distribution warehouse, and it is possible to reduce the number of transport vehicles waiting in the distribution warehouse.
　また、さらに、前記第一搬送車両に設けられ、前記第一到着予定情報を送信する送信部と、前記送信部により送信された前記第一到着予定情報を受信する受信部と、前記第一搬送車両の位置を検出する位置検出部と、前記送信部による前記第一到着予定情報の送信を制御する送信制御部と、を備え、前記第一搬送車両が前記物流倉庫の位置を基準とした所定範囲内に位置することが前記位置検出部により検出されると、（ｉ）前記通知部は、前記所定範囲内に前記第一搬送車両が位置することを前記第一搬送車両に通知し、（ｉｉ）前記送信制御部は、前記送信部による前記第一到着予定情報の送信を許可してもよい。 A transmission unit provided in the first transport vehicle for transmitting the first arrival schedule information; a reception unit for receiving the first arrival schedule information transmitted by the transmission unit; A position detection unit that detects the position of the vehicle, and a transmission control unit that controls the transmission of the first arrival schedule information by the transmission unit, wherein the first transport vehicle has a predetermined position based on the position of the distribution warehouse. When the position detecting unit detects that the first transport vehicle is located within the range, the notification unit notifies the first transport vehicle that the first transport vehicle is located within the predetermined range, ii) The transmission control unit may allow the transmission unit to transmit the first arrival schedule information.
　これによれば、第一搬送車両が物流倉庫の所定範囲内まで近づいた段階で、第一搬送車両の送信部における第一到着予定情報の送信を許可するため、物流倉庫は、第一搬送車両のより精度のよい到着予定時刻を取得することができる。このため、第一搬送車両に対する準備が完了するまでの時刻を、第一搬送車両の到着予定時刻に精度よく合わせることができる。よって、第一搬送車両が物流倉庫において待機する時間を低減することができる。また、物流倉庫で準備が完了した荷物をすぐに第一搬送車両に移載する作業を開始できるため、物流倉庫内で準備が完了した荷物を載置しておくスペースを削減することができる。 According to this, at the stage where the first transport vehicle approaches the predetermined range of the distribution warehouse, the transmission unit of the first transport vehicle permits transmission of the first arrival schedule information. , A more accurate estimated arrival time can be obtained. Therefore, the time until the preparation for the first transport vehicle is completed can be accurately adjusted to the estimated arrival time of the first transport vehicle. Therefore, the time during which the first transport vehicle waits in the distribution warehouse can be reduced. Further, since the operation of immediately transferring the prepared luggage to the first transport vehicle in the distribution warehouse can be started, the space for storing the prepared luggage in the distribution warehouse can be reduced.
　また、さらに、前記第一搬送車両の現在位置に基づく前記第一搬送車両が前記物流倉庫に到着する予定に関する第二到着予定情報を算出する算出部と、前記第一到着予定情報と前記第二到着予定情報との間の所定の相違の有無を判定する判定部と、を備え、前記制御部は、前記判定部により前記所定の相違が有ると判定されると、前記第一搬送車両に対して既に前記出庫の準備が完了している荷の中に配送予定としている荷が含まれ、かつ、当該第一搬送車両よりも前記物流倉庫に早く到着する予定の第二搬送車両を検索し、前記第二搬送車両が存在する場合、前記出庫の準備が完了している荷の中の前記配送予定としている前記荷を前記第二搬送車両への準備品として前記第二搬送車両に割り当ててもよい。 A calculating unit configured to calculate second arrival schedule information on a schedule of the first transport vehicle to arrive at the distribution warehouse based on a current position of the first transport vehicle; A determination unit that determines whether there is a predetermined difference between the arrival schedule information and the first transfer vehicle, when the determination unit determines that the predetermined difference is present, Search for a second transport vehicle that is scheduled to arrive at the distribution warehouse earlier than the first transport vehicle, including the cargo that is to be delivered among the loads that have already been prepared for delivery. When the second transport vehicle is present, the load to be delivered among the loads that have been prepared for delivery may be assigned to the second transport vehicle as supplies to the second transport vehicle. Good.
　これによれば、第一搬送車両が物流倉庫に第一到着予定情報による到着予定よりも、第一搬送車両の現在位置に基づく物流倉庫への到着予定が遅くなると判定された場合、物流倉庫において第一搬送車両のための出庫の準備が完了している荷のうちの少なくとも一部を、第一搬送車両よりも物流倉庫に早く到着する予定の第二搬送車両の準備品として割り当てる。このため、第一搬送車両のための出庫の準備が完了している荷の少なくとも一部を、第一搬送車両が到着しなくても第二搬送車両が到着すれば第二搬送車両に移載する作業を開始することができる。よって、搬送車両の位置に応じて、準備が完了している荷を搬送させる搬送車両の割り当てを変更することで、出庫の準備を効率よく行うことができる。 According to this, when it is determined that the first transport vehicle arrives at the distribution warehouse based on the current position of the first transport vehicle later than the scheduled arrival at the distribution warehouse based on the first arrival schedule information, At least a portion of the load that is ready to leave for the first transport vehicle is assigned as a second transport vehicle preparation item that is scheduled to arrive at the distribution warehouse earlier than the first transport vehicle. For this reason, at least a part of the load that has been prepared for delivery for the first transport vehicle is transferred to the second transport vehicle if the second transport vehicle arrives even if the first transport vehicle does not arrive. Work can be started. Therefore, by changing the assignment of the transport vehicles for transporting the ready-to-load cargos according to the position of the transport vehicles, the preparation for delivery can be efficiently performed.
　また、前記通知部は、前記第一搬送車両の到着を前記物流倉庫が受け入れ可能な時間を、前記遅延情報として通知してもよい。 The notifying unit may notify, as the delay information, a time when the distribution warehouse can accept the arrival of the first transport vehicle.
　このため、第一搬送車両の運転手に、受け入れ可能な時間までの時間を有効に使うことを促すことができ、物流倉庫において搬送車両が待機する時間を低減することができる。 Therefore, it is possible to encourage the driver of the first transport vehicle to effectively use the time up to an acceptable time, and to reduce the time during which the transport vehicle waits in the distribution warehouse.
　また、前記通知部は、前記第一搬送車両の現在位置から所定の距離以内にある他の物流倉庫を前記遅延情報として通知してもよい。 The notifying unit may notify another distribution warehouse located within a predetermined distance from a current position of the first transport vehicle as the delay information.
　このため、第一搬送車両の運転手に、第一搬送車両の近くにある他の物流倉庫に行くことを優先させることを促すことができ、物流倉庫において搬送車両が待機する時間を低減することができる。 Therefore, it is possible to encourage the driver of the first transport vehicle to give priority to going to another distribution warehouse near the first transport vehicle, and to reduce the waiting time of the transport vehicle in the distribution warehouse. Can be.
　また、前記通知部は、前記第一到着予定情報に基づく前記第一搬送車両が前記物流倉庫に到着する到着予定時刻から、前記遅延による前記準備が完了するまでにかかると予測される遅延時間を前記遅延情報として通知してもよい。 Further, the notifying unit is configured to calculate a delay time estimated to be required until the preparation due to the delay is completed from the estimated arrival time at which the first transport vehicle arrives at the distribution warehouse based on the first arrival information. It may be notified as the delay information.
　このため、第一搬送車両の運転手に、受け入れ可能となるまでにかかる時間を知らせることができるため、物流倉庫が受け入れ可能な時間までの時間を有効に使うことを促すことができ、物流倉庫において搬送車両が待機する時間を低減することができる。 For this reason, the driver of the first transport vehicle can be notified of the time required until the logistics can be accepted. In this case, the time during which the transport vehicle waits can be reduced.
　また、本発明の一態様に係る物流方法は、荷が格納される物流倉庫を備え、複数の搬送車両により荷が搬送される物流システムによる物流方法であって、前記複数の搬送車両のうちの第一搬送車両が前記物流倉庫に到着する予定に関する第一到着予定情報を取得し、前記第一到着予定情報に基づき前記物流倉庫における荷の入庫または出庫の準備の計画である準備計画を生成し、前記準備計画に従って前記準備を前記物流倉庫に指示し、前記物流倉庫における前記準備計画の進捗を監視し、前記準備計画からの前記準備の遅延が検出されると、前記第一搬送車両に対して遅延情報を通知する。 In addition, a distribution method according to an aspect of the present invention includes a distribution warehouse in which loads are stored, and is a distribution method using a distribution system in which loads are transported by a plurality of transport vehicles. The first transfer vehicle acquires first arrival schedule information regarding a schedule to arrive at the distribution warehouse, and generates a preparation plan that is a plan for preparation of loading or unloading of the load in the distribution warehouse based on the first arrival schedule information. Instructing the preparation to the distribution warehouse according to the preparation plan, monitoring the progress of the preparation plan in the distribution warehouse, when the delay of the preparation from the preparation plan is detected, with respect to the first transport vehicle Notification of delay information.
　これによれば、物流倉庫に到着予定の第一搬送車両からの第一到着予定情報に基づく準備計画が遅延している場合に、第一搬送車両に対して遅延情報を通知することで、第一搬送車両の運転手に、物流倉庫の第一搬送車両に対する準備が遅延していることを知らせることができる。これにより、例えば、運転手に、準備計画からの準備の遅延を考慮して物流倉庫に到着するまでの時間を有効に使うことを促すことができる。よって、物流倉庫において搬送車両が待機する時間を低減することができ、物流倉庫において待機する搬送車両の数を低減することができる。 According to this, when the preparation plan based on the first arrival schedule information from the first delivery vehicle scheduled to arrive at the distribution warehouse is delayed, the first delivery vehicle is notified of the delay information, The driver of one transfer vehicle can be notified that preparation for the first transfer vehicle in the distribution warehouse is delayed.

　［１．物流システムの構成概要］
　まず、図１を用いて、本発明の実施の形態に係る物流システム１０の構成概要を説明する。図１は、実施の形態に係る物流システム１０の構成概要を示す図である。図１に示すように、本実施の形態に係る物流システム１０は、図示しない運転手が使用する作業端末１００と、配送作業を管理する管理システム３００と、複数の搬送車両２０１、２０２により、搬送された荷、および／または搬送される荷が格納される物流倉庫４００と、を備える。 [1. Outline of logistics system configuration]
First, a configuration outline of a distribution system 10 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram illustrating a schematic configuration of a distribution system 10 according to the embodiment. As shown in FIG. 1, a logistics system 10 according to the present embodiment uses a work terminal 100 used by a driver (not shown), a management system 300 that manages a delivery operation, and a plurality of transfer vehicles 201 and 202, which are used for transportation. And / or a distribution warehouse 400 in which the transferred load and / or the load to be transported are stored.
　管理システム３００は、各搬送車両２０１、２０２に対応付けられている作業端末１００から各搬送車両２０１、２０２が向かう先の物流倉庫４００に到着する予定などの情報を、作業端末１００との間でやり取りし、各搬送車両２０１、２０２の物流倉庫４００への到着予定時刻を管理する。また、管理システム３００は、到着する予定の各搬送車両２０１、２０２に割り当てられている荷について、物流倉庫４００における入庫または出庫の準備を行う。これにより、管理システム３００は、各搬送車両２０１、２０２が物流倉庫４００に滞在する時間が短くなるように管理する。管理システム３００は、サーバなどのコンピュータにより実現される。 The management system 300 transmits information such as a schedule to arrive at the distribution warehouse 400 to which each of the transport vehicles 201 and 202 travels from the work terminal 100 associated with each of the transport vehicles 201 and 202 with the work terminal 100. It exchanges and manages the scheduled arrival times of the transport vehicles 201 and 202 at the distribution warehouse 400. In addition, the management system 300 prepares entry or exit from the distribution warehouse 400 for the cargo assigned to each of the transport vehicles 201 and 202 that are to arrive. Thereby, the management system 300 manages the transportation vehicles 201 and 202 such that the time during which the transportation vehicles 201 and 202 stay in the distribution warehouse 400 is shortened. The management system 300 is realized by a computer such as a server.
　作業端末１００は、搬送車両２０１に対応付けられている端末である。なお、図示しないが、搬送車両２０２にも別の作業端末が対応付けられている。以下、どの作業端末の構成も同じものであるとして、説明する。作業端末１００は、例えば、スマートフォン、タブレット端末、ＰＣ（Ｐｅｒｓｏｎａｌ　Ｃｏｍｐｕｔｅｒ）などのコンピュータにより実現される。作業端末１００は、運転手から所定の入力を受け付ける。例えば、運転手は、作業端末１００を手に取り、所定の操作を行う。これにより、作業端末１００は、管理システム３００から配送作業情報を受信する。運転手は、作業端末１００に表示された情報に従い、搬送車両２０１を用いて複数の荷の配送または受け取りを、到着先の物流倉庫４００に対して行う。また、作業端末１００は、運転手から他の操作を受け付けることで、到着先の物流倉庫４００への到着予定時刻を管理システム３００に送信する。 Work terminal 100 is a terminal associated with transport vehicle 201. Although not shown, another work terminal is also associated with the transport vehicle 202. Hereinafter, description will be made assuming that the configuration of each work terminal is the same. The work terminal 100 is realized by a computer such as a smartphone, a tablet terminal, and a PC (Personal Computer). The work terminal 100 receives a predetermined input from a driver. For example, the driver picks up the work terminal 100 and performs a predetermined operation. Thus, the work terminal 100 receives the delivery work information from the management system 300. The driver uses the transport vehicle 201 to deliver or receive a plurality of loads to the destination distribution warehouse 400 according to the information displayed on the work terminal 100. In addition, the work terminal 100 transmits the scheduled arrival time at the destination distribution warehouse 400 to the management system 300 by receiving another operation from the driver.
　また、作業端末１００は、ＧＰＳ（Ｇｌｏｂａｌ　Ｐｏｓｉｔｉｏｎｉｎｇ　Ｓｙｓｔｅｍ）を利用して作業端末１００の位置を示す位置情報を取得し、位置情報と搬送車両ＩＤとを管理システム３００に送信する機能を有する。作業端末１００は、例えば、所定の期間ごとに位置情報と搬送車両ＩＤとを管理システム３００に送信する。この場合、作業端末１００には、予め搬送車両ＩＤが対応付けられているものとする。また、作業端末１００は、これら位置情報と搬送車両ＩＤとを、例えば日時と紐づけて記憶する。 The work terminal 100 has a function of acquiring position information indicating the position of the work terminal 100 using GPS (Global Positioning System), and transmitting the position information and the transport vehicle ID to the management system 300. The work terminal 100 transmits the position information and the transport vehicle ID to the management system 300 at predetermined intervals, for example. In this case, it is assumed that the transport vehicle ID is associated with the work terminal 100 in advance. The work terminal 100 stores the position information and the transport vehicle ID in association with, for example, the date and time.
　物流倉庫４００は、コンピュータなどの操作端末を含む。物流倉庫４００は、管理システム３００から所定のタイミングで、各搬送車両２０１、２０２の到着予定時刻までに各搬送車両２０１、２０２に割り当てられている荷であって、物流倉庫４００における入庫または出庫する荷を準備する指示を示す指示情報を取得する。物流倉庫４００は、各搬送車両２０１、２０２の到着予定時刻に間に合うように、各搬送車両２０１、２０２に割り当てられている、（ｉ）荷を入庫する準備、または、（ｉｉ）荷を出庫する準備を行う。 The distribution warehouse 400 includes an operation terminal such as a computer. The distribution warehouse 400 is a load assigned to each of the transport vehicles 201 and 202 by the scheduled arrival time of each of the transport vehicles 201 and 202 at a predetermined timing from the management system 300, and enters or leaves the distribution warehouse 400. Acquire instruction information indicating an instruction to prepare a load. The distribution warehouse 400 is assigned to each of the transport vehicles 201 and 202 so as to be ready for the scheduled arrival time of each of the transport vehicles 201 and 202, and (i) prepares to receive a load or (ii) unloads the load. Get ready.
　具体的には、荷を入庫する準備では、各搬送車両２０１、２０２が到着する時刻までに、各搬送車両２０１、２０２が搬送している荷のうちで入出庫情報に基づく荷を物流倉庫４００に入庫するための作業者および作業車両を物流倉庫４００の所定のバースへの割り当てが行われる。物流倉庫４００は、例えば、荷を入庫する搬送車両の台数に応じて、入庫に使用するバースの数、作業者の人数、および、作業車両の台数を変更してもよい。また、荷を入庫する準備では、既に他の搬送車両により搬送された入庫品がバースに置かれている場合において、置かれている荷物を物流倉庫４００内に入庫することにより当該バースを空ける作業が行われる。 Specifically, in preparation for loading the cargo, by the time when each of the transport vehicles 201 and 202 arrives, the loads based on the loading / unloading information among the loads transported by the transport vehicles 201 and 202 are distributed to the distribution warehouse 400. Are assigned to a predetermined berth of the distribution warehouse 400 for the workers and work vehicles to enter the warehouse. The distribution warehouse 400 may change, for example, the number of berths used for warehousing, the number of workers, and the number of working vehicles according to the number of transport vehicles that receive the load. In addition, in the preparation for storing the cargo, in the case where the goods received by another transport vehicle have already been placed on the berth, the berth is emptied by loading the placed luggage into the distribution warehouse 400. Is performed.
　また、荷を出庫する準備では、各搬送車両２０１、２０２が到着する時刻までに、入出庫情報に基づく荷を物流倉庫４００から出庫するための出庫準備が行われ、出庫準備が完了した荷物が物流倉庫４００の所定のバースに対応する荷さばき場に載置される。 In preparation for unloading the cargo, by the time each of the transport vehicles 201 and 202 arrives, preparations for unloading the load based on the entry / exit information from the distribution warehouse 400 are performed. It is placed on a loading place corresponding to a predetermined berth of the distribution warehouse 400.
　なお、物流倉庫４００は、管理システム３００と情報のやり取りを行う、例えば、スマートフォン、タブレット端末、ＰＣ（Ｐｅｒｓｏｎａｌ　Ｃｏｍｐｕｔｅｒ）などのコンピュータにより実現される。 Note that the distribution warehouse 400 exchanges information with the management system 300, and is realized by a computer such as a smartphone, a tablet terminal, and a PC (Personal Computer).
　なお、入出庫情報は、各搬送車両２０１、２０２が各到着先の物流倉庫に入庫する荷の数に関する情報、または、各到着先の物流倉庫から出庫する荷の数に関する情報を含む。荷の数に関する情報とは、例えば、荷の種類と、当該種類の荷の数とが対応付けられた情報である。 入 Note that the entry / exit information includes information on the number of loads that each of the transport vehicles 201 and 202 enters the distribution warehouse at each destination, or information on the number of loads leaving the distribution warehouse at each destination. The information on the number of loads is, for example, information in which types of loads are associated with the number of loads of the type.
　［２．物流システムの具体的な構成］
　次に、物流システム１０の具体的な構成について図２を用いて説明する。 [2. Specific configuration of distribution system]
Next, a specific configuration of the distribution system 10 will be described with reference to FIG.
　図２は、実施の形態にかかる物流システム１０の機能構成の一例を示すブロック図である。 FIG. 2 is a block diagram illustrating an example of a functional configuration of the distribution system 10 according to the embodiment.
　図２に示すように、物流システム１０は、搬送車両２０１に設けられる作業端末１００と、管理システム３００と、物流倉庫４００とを備える。作業端末１００、管理システム３００および物流倉庫４００は、互いに、図示しない通信ネットワークにより通信可能に接続されている。通信ネットワークは、例えば、インターネットなどの汎用のネットワークであってもよいし、専用回線などの専用のネットワークであってもよい。 As shown in FIG. 2, the distribution system 10 includes a work terminal 100 provided on the transport vehicle 201, a management system 300, and a distribution warehouse 400. The work terminal 100, the management system 300, and the distribution warehouse 400 are communicably connected to each other by a communication network (not shown). The communication network may be, for example, a general-purpose network such as the Internet, or a dedicated network such as a dedicated line.
　まず、作業端末１００の機能構成について説明する。 First, a functional configuration of the work terminal 100 will be described.
　作業端末１００は、機能構成として、通信部１０１、制御部１０２、入力受付部１０３、位置検出部１０４および表示部１０５を備える。 The work terminal 100 includes a communication unit 101, a control unit 102, an input reception unit 103, a position detection unit 104, and a display unit 105 as functional components.
　通信部１０１は、管理システム３００との間で情報を送受信する。つまり、通信部１０１は、情報を送信する送信部としての機能と、情報を受信する受信部としての機能とを有する。通信部１０１は、管理システム３００から受信した情報を制御部１０２に出力する。また、通信部１０１は、制御部１０２により出力された情報を管理システム３００に送信する。通信部１０１は、例えば、搬送車両２０１が物流倉庫４００に到着する予定に関する第一到着予定情報を送信する。なお、通信部１０１は、例えば、通信ネットワークと通信接続することが可能な通信モジュールなどの通信ＩＦ（Ｉｎｔｅｒｆａｃｅ）により実現される。 The communication unit 101 transmits and receives information to and from the management system 300. That is, the communication unit 101 has a function as a transmitting unit for transmitting information and a function as a receiving unit for receiving information. The communication unit 101 outputs information received from the management system 300 to the control unit 102. In addition, the communication unit 101 transmits the information output by the control unit 102 to the management system 300. The communication unit 101 transmits, for example, first arrival schedule information regarding a schedule in which the transport vehicle 201 will arrive at the distribution warehouse 400. The communication unit 101 is realized by, for example, a communication IF (Interface) such as a communication module that can be connected to a communication network.
　制御部１０２は、所定のアプリケーションを実行して、表示部１０５にＧＵＩ（Ｇｒａｐｈｉｃａｌ　Ｕｓｅｒ　Ｉｎｔｅｒｆａｃｅ）を表示させ、入力受付部１０３が運転手から受け付けた、ＧＵＩに対する入力に応じた情報を通信部１０１に管理システム３００へ送信させる。制御部１０２は、運転手によりＧＵＩで選択された次の到着先の物流倉庫を示す情報を通信部１０１に送信させる。例えば、制御部１０２は、ＧＵＩへの入力に応じて、第一到着予定情報を通信部１０１に管理システム３００へ送信させる。なお、ＧＵＩの詳細は、後述する。 The control unit 102 executes a predetermined application to display a GUI (Graphical User Interface) on the display unit 105, and transmits to the communication unit 101 information corresponding to the GUI input received by the input receiving unit 103 from the driver. It is transmitted to the management system 300. The control unit 102 causes the communication unit 101 to transmit information indicating the distribution warehouse of the next destination selected by the driver on the GUI. For example, the control unit 102 causes the communication unit 101 to transmit the first arrival schedule information to the management system 300 according to the input to the GUI. The details of the GUI will be described later.
　第一到着予定情報は、搬送車両２０１が物流倉庫４００に到着する予定の時刻または時間帯を含む。また、第一到着予定情報は、さらに、搬送車両２０１の物流倉庫４００における入出庫情報を含んでいてもよい。なお、第一到着予定情報は、搬送車両２０１の現在位置を示す情報であってもよい。この場合、例えば、現在位置を取得した管理システム３００は、現在位置から到着先の物流倉庫４００への移動に要する時間を現在時刻に加算した時刻を、到着予定時刻として推定してもよい。また、第一到着予定情報は、物流倉庫４００が備える複数のバースに割り当てられている予約状況に応じて予約が確定されたときに決定された予約時間帯に基づく時刻（例えば、予約時間帯の開始時刻）であってもよい。また、第一到着予定情報は、各搬送車両に予め定められた時刻であってもよい。 The first arrival schedule information includes the scheduled time or time zone when the transport vehicle 201 arrives at the distribution warehouse 400. Further, the first scheduled arrival information may further include entry / exit information of the transport vehicle 201 in the distribution warehouse 400. The first arrival schedule information may be information indicating the current position of the transport vehicle 201. In this case, for example, the management system 300 that has acquired the current position may estimate the time obtained by adding the time required to move from the current position to the destination distribution warehouse 400 to the current time as the estimated arrival time. Further, the first arrival schedule information is a time based on a reservation time zone determined when the reservation is confirmed according to the reservation status allocated to the plurality of berths provided in the distribution warehouse 400 (for example, the time of the reservation time zone). (Start time). Further, the first scheduled arrival information may be a time preset for each transport vehicle.
　また、制御部１０２は、位置検出部１０４により検出されている作業端末１００の現在位置（つまり、搬送車両２０１の現在位置）を定期的に取得し、取得した現在位置を示す位置情報を通信部１０１に管理システム３００へ送信させる。これにより、通信部１０１は、定期的に位置情報を管理システム３００に送信する。制御部１０２は、例えば、プロセッサ、および、所定のアプリケーションのプログラムを記憶しているメモリなどにより実現される。 Further, the control unit 102 periodically acquires the current position of the work terminal 100 detected by the position detection unit 104 (that is, the current position of the transport vehicle 201), and transmits position information indicating the acquired current position to the communication unit. 101 is transmitted to the management system 300. Thereby, the communication unit 101 periodically transmits the position information to the management system 300. The control unit 102 is realized by, for example, a processor and a memory that stores a program of a predetermined application.
　入力受付部１０３は、運転手からの入力を受け付け、受け付けた入力を制御部１０２に出力する。入力受付部１０３は、例えば、タッチパネル、タッチパッド、キーボード、マウスなどの入力ＩＦ（Ｉｎｔｅｒｆａｃｅ）により実現される。 The input receiving unit 103 receives an input from the driver, and outputs the received input to the control unit 102. The input receiving unit 103 is realized by, for example, an input IF (Interface) such as a touch panel, a touch pad, a keyboard, and a mouse.
　位置検出部１０４は、ＧＰＳ衛星を含む人工衛星から当該作業端末１００の位置を示す情報を受信する。つまり、位置検出部１０４は、搬送車両２０１の現在位置を検出する。位置検出部１０４は、例えば、ＧＰＳ受信機などにより実現される。 The position detection unit 104 receives information indicating the position of the work terminal 100 from artificial satellites including GPS satellites. That is, the position detection unit 104 detects the current position of the transport vehicle 201. The position detection unit 104 is realized by, for example, a GPS receiver or the like.
　表示部１０５は、制御部１０２での処理結果を表示する。具体的には、表示部１０５は、制御部１０２により出力されたＧＵＩを表示する。表示部１０５は、例えば、液晶ディスプレイ、有機ＥＬディスプレイなどにより実現される。 (4) The display unit 105 displays the processing result of the control unit 102. Specifically, the display unit 105 displays the GUI output by the control unit 102. The display unit 105 is realized by, for example, a liquid crystal display, an organic EL display, or the like.
　次に、管理システム３００の機能構成について説明する。 Next, the functional configuration of the management system 300 will be described.
　管理システム３００は、機能構成として、通信部３０１、制御部３０２、送信制御部３０３、算出部３０４および判定部３０５を備える。 The management system 300 includes a communication unit 301, a control unit 302, a transmission control unit 303, a calculation unit 304, and a determination unit 305 as functional components.
　通信部３０１は、作業端末１００または物流倉庫４００との間で情報を送受信する。つまり、通信部３０１は、情報を送信する送信部としての機能と、情報を受信する受信部としての機能とを有する。通信部３０１は、作業端末１００または物流倉庫４００から受信した情報を制御部３０２または送信制御部３０３に出力する。通信部３０１は、例えば、第一到着予定情報を受信し、当該第一到着予定情報を制御部３０２および判定部３０５に出力する。また、通信部３０１は、例えば、位置情報を受信し、当該位置情報を送信制御部３０３および算出部３０４に出力する。また、通信部３０１は、制御部３０２により出力された情報を作業端末１００または物流倉庫４００に送信する。通信部３０１は、例えば、通信ネットワークと通信接続することが可能な通信モジュールなどの通信ＩＦにより実現される。 The communication unit 301 transmits and receives information to and from the work terminal 100 or the distribution warehouse 400. That is, the communication unit 301 has a function as a transmitting unit for transmitting information and a function as a receiving unit for receiving information. The communication unit 301 outputs information received from the work terminal 100 or the distribution warehouse 400 to the control unit 302 or the transmission control unit 303. The communication unit 301 receives, for example, first arrival schedule information, and outputs the first arrival schedule information to the control unit 302 and the determination unit 305. In addition, the communication unit 301 receives, for example, position information and outputs the position information to the transmission control unit 303 and the calculation unit 304. The communication unit 301 transmits the information output by the control unit 302 to the work terminal 100 or the distribution warehouse 400. The communication unit 301 is realized by, for example, a communication IF such as a communication module capable of communication connection with a communication network.
　制御部３０２は、通信部３０１を介して、作業端末１００から第一到着予定情報を取得する。そして、制御部３０２は、取得した第一到着予定情報に基づき物流倉庫４００における荷の入庫または出庫の準備（以下、「入出庫準備」とする）の計画である準備計画を生成し、生成した準備計画に従って入出庫準備を物流倉庫４００に指示する。これにより、制御部３０２は、入出庫準備の指示を示す指示情報を通信部３０１に物流倉庫４００へ送信させる。 The control unit 302 acquires the first arrival schedule information from the work terminal 100 via the communication unit 301. Then, the control unit 302 generates and generates a preparation plan, which is a plan of preparation for loading or unloading of the cargo in the distribution warehouse 400 (hereinafter, referred to as “preparing for loading and unloading”) based on the obtained first arrival schedule information. Instructing the logistics warehouse 400 to prepare for entry and exit according to the preparation plan. Thereby, the control unit 302 causes the communication unit 301 to transmit the instruction information indicating the instruction of the entrance / exit preparation to the distribution warehouse 400.
　なお、準備計画は、例えば、第一到着予定情報に含まれる入出庫準備に要する時間を考慮して、第一到着予定情報に基づく到着予定時刻よりも、上記時間だけ前の時刻に、入出庫準備を物流倉庫４００に開始させる時刻を示す時刻情報を含む。 It should be noted that the preparation plan is, for example, taking into account the time required for the entry / exit preparation included in the first arrival schedule information, the entry / exit time at the time earlier than the estimated arrival time based on the first arrival schedule information by the above time. Time information indicating the time when the preparation is started in the distribution warehouse 400 is included.
　入出庫準備は、複数の準備工程により構成される。複数の準備工程には、例えば、荷を物流倉庫４００から出庫する工程、出庫した荷を梱包する場所まで搬送する工程、搬送した荷を梱包する工程、梱包した荷をバースまで搬送する工程などが含まれる。 (4) The entry / exit preparation consists of a plurality of preparation steps. The plurality of preparation steps include, for example, a step of unloading the load from the distribution warehouse 400, a step of transporting the unloaded load to a place for packing, a step of packing the transferred load, a step of transferring the packed load to the berth, and the like. included.
　なお、制御部３０２は、物流倉庫４００のバースに予約が確定されたときの予約時間帯を第一到着予定情報として取得する場合、以下の処理を行う。 The control unit 302 performs the following processing when acquiring the reservation time zone when the reservation at the berth of the distribution warehouse 400 is confirmed as the first arrival schedule information.
　まず、制御部３０２は、（ｉ）入出庫に要する時間、（ｉｉ）搬送車両が入れ替わるのに要する時間、および、（ｉｉｉ）マージン時間（つまり、予め定められた固定時間）を積算した時間（以下、「滞在時間」とする）を算出する。 First, the control unit 302 calculates (i) the time required for entering and leaving the car, (ii) the time required for the transfer vehicle to be switched, and (iii) the time obtained by integrating the margin time (that is, a predetermined fixed time) ( Hereinafter, “stay time” is calculated.
　そして、制御部３０２は、荷の入出庫の予約がされていない時間帯を有するバースの中から、滞在時間以上の時間の時間帯を示す予約可能時間帯情報を、通信部３０１に作業端末１００へ送信させる。 Then, the control unit 302 transmits the reservable time zone information indicating the time zone longer than the stay time to the communication terminal 301 from the berth having the time zone in which the loading / unloading of the cargo is not reserved. To send to.
　なお、予約可能時間帯情報として、入出庫準備に要する時間や搬送車両２０１の位置情報から算出した到着予定時刻、作業者が指定した時間帯、作業端末１００からの予約の受け付けた時刻に基づいた情報のみを送信してもよい。 Note that the reservable time zone information is based on the time required for entry / exit preparation, the estimated arrival time calculated from the position information of the transport vehicle 201, the time zone specified by the worker, and the time at which the reservation from the work terminal 100 was received. Only information may be transmitted.
　制御部３０２は、物流倉庫４００から予約状況を示す情報を取得しているものとする。 It is assumed that the control unit 302 has obtained information indicating the reservation status from the distribution warehouse 400.
　そして作業端末１００は、例えば、予約可能時間帯情報を受信すると、後述する図７に示すような時間帯選択画面１１３を表示させ、作業者によって選択された時間帯を第一到着予定情報として送信する。 When the work terminal 100 receives, for example, the reservable time zone information, the work terminal 100 displays a time zone selection screen 113 as shown in FIG. 7 described later, and transmits the time zone selected by the worker as the first arrival schedule information. I do.
　送信制御部３０３は、作業端末１００の通信部１０１による第一到着予定情報の送信を制御する。具体的には、送信制御部３０３は、通信部３０１を介して、通信部１０１による第一到着予定情報の送信の許可を示す許可情報を、作業端末１００へ送信することを制御することで、作業端末１００の通信部１０１による第一到着予定情報の送信を制御する。送信制御部３０３は、取得した位置情報に応じて、作業端末１００が設けられている搬送車両２０１の位置を取得し、搬送車両２０１が第一到着予定情報による到着先の物流倉庫４００の位置を基準とした所定範囲内に位置する場合、通信部３０１に作業端末１００へ許可情報を送信させる。また、この時、通信部３０１は、所定範囲内に搬送車両２０１が位置することを搬送車両２０１の作業端末１００に通知する。これにより、作業端末１００は、所定範囲内に搬送車両２０１が位置したことを示す情報を、運転手に通知する。例えば、作業端末１００は、所定範囲内に搬送車両２０１が位置したことを示す情報を、ＧＵＩにおいて表示部１０５に表示してもよいし、図示しないスピーカから音声として出力してもよい。 The transmission control unit 303 controls the transmission of the first arrival schedule information by the communication unit 101 of the work terminal 100. Specifically, the transmission control unit 303 controls transmission of permission information indicating permission of transmission of the first arrival schedule information by the communication unit 101 to the work terminal 100 via the communication unit 301, The transmission of the first arrival schedule information by the communication unit 101 of the work terminal 100 is controlled. The transmission control unit 303 acquires the position of the transport vehicle 201 provided with the work terminal 100 according to the acquired position information, and determines the position of the distribution warehouse 400 where the transport vehicle 201 arrives according to the first arrival schedule information. When the communication terminal 301 is located within the reference predetermined range, the communication unit 301 transmits the permission information to the work terminal 100. At this time, the communication unit 301 notifies the work terminal 100 of the transport vehicle 201 that the transport vehicle 201 is located within the predetermined range. Thereby, the work terminal 100 notifies the driver of information indicating that the transport vehicle 201 is located within the predetermined range. For example, the work terminal 100 may display information indicating that the transport vehicle 201 is located within a predetermined range on the display unit 105 in a GUI, or may output the information as a sound from a speaker (not shown).
　なお、送信制御部３０３は、作業端末１００の位置検出部１０４が検出した位置に基づいて、搬送車両２０１が所定範囲内に位置するか否かを判定するとしたが、これに限らない。つまり、搬送車両２０１が所定範囲内に位置するか否かの判定は、送信制御部３０３により行われなくてもよく作業端末１００の位置検出部１０４が行ってもよい。この場合、作業端末１００は判定結果を管理システム３００に送信し、管理システム３００の送信制御部３０３は判定結果を用いて許可情報を送信するか否かを決定する。 Note that the transmission control unit 303 determines whether or not the transport vehicle 201 is located within a predetermined range based on the position detected by the position detection unit 104 of the work terminal 100, but is not limited thereto. That is, the determination whether or not the transport vehicle 201 is located within the predetermined range may not be performed by the transmission control unit 303, and may be performed by the position detection unit 104 of the work terminal 100. In this case, the work terminal 100 transmits the determination result to the management system 300, and the transmission control unit 303 of the management system 300 determines whether to transmit the permission information using the determination result.
　なお、送信制御部３０３の機能は、管理システム３００が有していなくてもよく、作業端末１００が有していてもよい。この場合の送信制御部は、許可情報を出力せずに、上記の第一到着予定情報の送信の制御を行ってもよい。 The function of the transmission control unit 303 may not be included in the management system 300, and may be included in the work terminal 100. In this case, the transmission control unit may control the transmission of the first arrival schedule information without outputting the permission information.
　なお、作業端末１００は、許可情報を受信していない状態では、第一到着予定情報の送信が許可されていないため、第一到着予定情報の送信ができない状態に制限されている。作業端末１００は、許可情報を受信すると、第一到着予定情報の送信ができる状態となる。具体的には、作業端末１００は、許可情報を受信していない状態では、ＧＵＩ上で第一到着予定情報の送信を受け付けるボタンが表示されない、つまり、第一到着予定情報を送信するＧＵＩが表示されない状態となる。また、作業端末１００は、許可情報を受信していない状態では、ＧＵＩ上で第一到着予定情報の送信するボタンへの入力を受け付けた場合に、第一到着予定情報を送信しなくてもよいし、送信しない場合に送信できない旨を示すエラーを表示または音声で通知してもよい。また、作業端末１００は、所定範囲から外れた位置に位置した場合に、再び第一到着予定情報の送信ができない状態に制限されてもよい。つまり、作業端末１００は、作業端末１００が所定範囲内に位置する場合のみにおいて、第一到着予定情報の送信が許可されてもよい。 In the state where the permission information is not received, the work terminal 100 is not permitted to transmit the first arrival schedule information, so that the work terminal 100 is limited to a state where the first arrival schedule information cannot be transmitted. When the work terminal 100 receives the permission information, the work terminal 100 is ready to transmit the first arrival schedule information. Specifically, the work terminal 100 does not display a button for accepting the transmission of the first arrival schedule information on the GUI in a state where the permission information is not received, that is, the GUI for transmitting the first arrival schedule information is displayed. It is in a state where it is not performed. In a state where the permission information is not received, the work terminal 100 may not transmit the first arrival schedule information when receiving an input to the button for transmitting the first arrival schedule information on the GUI. If not, an error indicating that transmission is not possible may be displayed or notified by voice. Further, when the work terminal 100 is located at a position outside the predetermined range, the work terminal 100 may be limited to a state in which the first arrival schedule information cannot be transmitted again. That is, the work terminal 100 may be permitted to transmit the first arrival schedule information only when the work terminal 100 is located within the predetermined range.
　算出部３０４は、位置検出部１０４により検出される搬送車両２０１の位置に基づいて、搬送車両２０１が物流倉庫４００に到着する予定に関する第二到着予定情報を算出する。算出部３０４は、例えば、取得した位置情報により示される搬送車両２０１の現在位置から、到着先の物流倉庫４００の位置までの経路を特定し、特定した経路を移動するのに要する移動時間を算出する。算出部３０４は、移動時間を、特定した経路の渋滞の有無を考慮して算出してもよい。算出部３０４は、現在時刻に移動時間を加算することで、搬送車両２０１が物流倉庫４００に到着する到着予定時刻を算出する。算出部３０４は、算出した第二到着予定情報を判定部３０５に出力する。 Calculating section 304 calculates second arrival schedule information on the schedule of transport vehicle 201 to arrive at distribution warehouse 400 based on the position of transport vehicle 201 detected by position detection section 104. The calculating unit 304 specifies, for example, a route from the current position of the transport vehicle 201 indicated by the obtained position information to the position of the destination distribution warehouse 400, and calculates a travel time required to move the specified route. I do. The calculation unit 304 may calculate the travel time in consideration of the presence or absence of the congestion on the specified route. The calculation unit 304 calculates the estimated arrival time at which the transport vehicle 201 arrives at the distribution warehouse 400 by adding the travel time to the current time. The calculation unit 304 outputs the calculated second arrival schedule information to the determination unit 305.
　判定部３０５は、第一到着予定情報と第二到着予定情報との間の所定の相違の有無を判定する。第一到着予定情報は、運転手により事前に選択された到着予定時刻を示しており、物流倉庫４００において荷の入出庫準備が行われる基準となる時刻を示す。一方で、第二到着予定情報は、現在位置から目的地までの移動に要すると予測される時間に基づいて算出された到着予定時刻を示す。このため、判定部３０５は、第一到着予定情報と第二到着予定情報とを比較することで、搬送車両２０１が第一到着予定情報に基づく当初の到着予定時刻よりも早く物流倉庫４００に到着するのか、遅く物流倉庫４００に到着するのか、あるいは一致するタイミングで物流倉庫４００に到着するのかを予測することができる。判定部３０５は、例えば、当初の到着予定時刻よりも所定時間（例えば２０分間）以上遅く到着する場合、所定の相違が有ると判定し、当初の到着予定時刻の所定時間後の時刻よりも早く到着する場合、所定の相違が無いと判定する。判定部３０５は、判定結果を制御部３０２に出力する。 The determination unit 305 determines whether there is a predetermined difference between the first scheduled arrival information and the second scheduled arrival information. The first scheduled arrival information indicates a scheduled arrival time selected in advance by the driver, and indicates a reference time at which preparations for loading and unloading the cargo in the distribution warehouse 400 are performed. On the other hand, the second arrival schedule information indicates the estimated arrival time calculated based on the time estimated to be required for traveling from the current position to the destination. For this reason, the determination unit 305 compares the first arrival schedule information with the second arrival schedule information, so that the transport vehicle 201 arrives at the distribution warehouse 400 earlier than the original expected arrival time based on the first arrival schedule information. It is possible to predict whether the user will arrive at the distribution warehouse 400 late or arrive at the distribution warehouse 400 at the same timing. For example, when arriving at least a predetermined time (for example, 20 minutes) later than the originally scheduled arrival time, the determination unit 305 determines that there is a predetermined difference, and earlier than a time after a predetermined time after the initially scheduled arrival time. When it arrives, it is determined that there is no predetermined difference. The determination unit 305 outputs a determination result to the control unit 302.
　制御部３０２は、判定部３０５から判定結果を取得し、判定部３０５により所定の相違が有ると判定されると、搬送車両２０１に対して既に出庫の準備が完了している荷の中に配送予定としている荷が含まれ、かつ、搬送車両２０１よりも物流倉庫４００に早く到着する予定の第二搬送車両を検索する。具体的には、管理システム３００では、複数の搬送車両のそれぞれから第一到着予定情報を取得しているため、第一到着予定情報に含まれる入出庫情報に基づいて、搬送車両２０１に対して既に出庫の準備が完了している荷の中に配送予定としている荷が含まれる第二搬送車両（例えば、搬送車両２０２）を特定することができる。また、管理システム３００では、複数の搬送車両のそれぞれから位置情報を取得しているため、複数の搬送車両のそれぞれについて、当該搬送車両が現在位置から物流倉庫４００までの移動に要する時間を算出することで、当該搬送車両の第二到着予定情報を算出することができる。よって、管理システム３００では、搬送車両２０１よりも物流倉庫４００に早く到着する予定の搬送車両２０２を検索することができる。制御部３０２は、第二搬送車両が存在する場合、出庫の準備が完了している荷の中の搬送車両２０２が配送予定としている荷を、検索して特定した搬送車両２０２への準備品として割り当てる。なお、制御部３０２は、搬送車両２０１よりも物流倉庫４００に早く到着する予定の第二搬送車両を特定するために、第二到着予定情報を用いるとしたが、これに限らずに、第一到着予定情報を用いてもよい。 The control unit 302 obtains the determination result from the determination unit 305, and when the determination unit 305 determines that there is a predetermined difference, the control unit 302 delivers the package to the transport vehicle 201 in a package that has already been prepared for delivery. A search is made for a second transport vehicle that includes the scheduled load and that is scheduled to arrive at the distribution warehouse 400 earlier than the transport vehicle 201. Specifically, in the management system 300, since the first scheduled arrival information is obtained from each of the plurality of transport vehicles, the transport vehicle 201 is determined based on the entry / exit information included in the first scheduled arrival information. It is possible to specify a second transport vehicle (for example, the transport vehicle 202) that includes a load that is scheduled to be delivered among loads that have already been prepared for delivery. Further, in the management system 300, since the position information is acquired from each of the plurality of transport vehicles, for each of the plurality of transport vehicles, the time required for the transport vehicle to move from the current position to the distribution warehouse 400 is calculated. Thereby, the second arrival schedule information of the transport vehicle can be calculated. Therefore, the management system 300 can search for the transport vehicle 202 that is scheduled to arrive at the distribution warehouse 400 earlier than the transport vehicle 201. When the second transport vehicle is present, the control unit 302 searches for a load scheduled to be delivered by the transport vehicle 202 among loads that have been prepared for delivery as a preparation for the transport vehicle 202 specified by searching. assign. The control unit 302 uses the second arrival schedule information in order to specify the second transport vehicle that is scheduled to arrive at the distribution warehouse 400 earlier than the transport vehicle 201. However, the present invention is not limited thereto. Arrival schedule information may be used.
　なお、制御部３０２、送信制御部３０３、算出部３０４および判定部３０５のそれぞれは、例えば、プロセッサ、および、所定のプログラムを記憶しているメモリなどにより実現される。なお、制御部３０２、送信制御部３０３、算出部３０４および判定部３０５のそれぞれは、共通のプロセッサおよびメモリにより構成されていてもよいし、独立したプロセッサおよびメモリにより構成されていてもよい。 Each of the control unit 302, the transmission control unit 303, the calculation unit 304, and the determination unit 305 is realized by, for example, a processor and a memory storing a predetermined program. In addition, each of the control unit 302, the transmission control unit 303, the calculation unit 304, and the determination unit 305 may be configured by a common processor and a memory, or may be configured by an independent processor and a memory.
　次に、物流倉庫４００の機能構成について説明する。 Next, the functional configuration of the distribution warehouse 400 will be described.
　物流倉庫４００は、機能構成として、通信部４０１、制御部４０２および監視部４０３を備える。 The distribution warehouse 400 includes a communication unit 401, a control unit 402, and a monitoring unit 403 as functional components.
　通信部４０１は、管理システム３００との間で情報を送受信する。つまり、通信部４０１は、情報を送信する送信部としての機能と、情報を受信する受信部としての機能とを有する。通信部４０１は、管理システム３００から受信した情報を制御部４０２に出力する。また、通信部４０１は、制御部４０２または監視部４０３により出力された情報を管理システム３００に送信する。通信部４０１は、例えば、入出庫準備の指示を示す指示情報を管理システム３００から受信する。通信部４０１は、例えば、監視部４０３により出力された準備計画からの準備の遅延を示す遅延情報を管理システム３００に送信する。なお、通信部４０１は、例えば、通信ネットワークと通信接続することが可能な通信モジュールなどの通信ＩＦ（Ｉｎｔｅｒｆａｃｅ）により実現される。 The communication unit 401 transmits and receives information to and from the management system 300. That is, the communication unit 401 has a function as a transmitting unit for transmitting information and a function as a receiving unit for receiving information. The communication unit 401 outputs information received from the management system 300 to the control unit 402. In addition, the communication unit 401 transmits information output by the control unit 402 or the monitoring unit 403 to the management system 300. The communication unit 401 receives, for example, instruction information from the management system 300, which indicates an instruction to prepare for entry and exit. The communication unit 401 transmits, to the management system 300, delay information indicating a delay in preparation from the preparation plan output by the monitoring unit 403, for example. The communication unit 401 is realized by, for example, a communication IF (Interface) such as a communication module that can be communicatively connected to a communication network.
　制御部４０２は、通信部４０１により受信された指示情報に基づいて、物流倉庫４００における入出庫準備を開始する。具体的には、制御部４０２は、各搬送車両２０１、２０２に割り当てられている荷であって、物流倉庫４００における入庫または出庫する荷を各搬送車両２０１、２０２の到着予定時刻までに準備する指示を表示装置に表示させることで、物流倉庫４００の作業者による作業を促す。また、制御部４０２は、物流倉庫４００の搬送装置、移載装置、パレタイズロボットなどの各機器を制御することで、各搬送車両２０１、２０２に割り当てられている荷を出庫してもよい。 The control unit 402 starts preparations for entering and leaving the distribution warehouse 400 based on the instruction information received by the communication unit 401. Specifically, the control unit 402 prepares a load assigned to each of the transport vehicles 201 and 202 to be entered or exited from the distribution warehouse 400 by the scheduled arrival time of each of the transport vehicles 201 and 202. By displaying the instruction on the display device, the worker of the distribution warehouse 400 is prompted to work. In addition, the control unit 402 may unload the load assigned to each of the transport vehicles 201 and 202 by controlling each device such as a transport device, a transfer device, and a palletizing robot in the distribution warehouse 400.
　監視部４０３は、物流倉庫４００における準備計画の進捗を監視する。監視部４０３は、具体的には、物流倉庫４００から複数の荷を出庫する場合、制御部４０２により制御されている各機器の作業の対象となっている荷がどの機器で作業されているか、作業対象となっている荷が準備計画の複数の荷のうちの何割の荷であるかを検出することで、準備計画の進捗を監視してもよい。また、監視部４０３は、作業者が作業の対象としている荷を作業者が所持している端末（図示せず）から検出された情報を用いて、準備計画の進捗を監視してもよい。また、この場合、監視部４０３は、作業者が荷の準備が完了した段階で、準備が完了した荷を示す情報を物流倉庫４００の入力装置（図示せず）において作業者が入力することで得られた情報を用いて、出庫する複数の荷のうち準備が完了した荷の割合を準備計画の進捗として監視してもよい。 The monitoring unit 403 monitors the progress of the preparation plan in the distribution warehouse 400. Specifically, when a plurality of loads are to be unloaded from the distribution warehouse 400, the monitoring unit 403 determines which device is performing the load of each device controlled by the control unit 402, The progress of the preparation plan may be monitored by detecting what percentage of the plurality of loads in the preparation plan the work subject load is. In addition, the monitoring unit 403 may monitor the progress of the preparation plan using information detected from a terminal (not shown) carried by the worker on the load that the worker is working on. Further, in this case, the monitoring unit 403 allows the operator to input information indicating the completed load on the input device (not shown) of the distribution warehouse 400 at the stage when the preparation of the load is completed. Using the obtained information, the ratio of the completed load among the plurality of loads to be delivered may be monitored as the progress of the preparation plan.
　監視部４０３は、準備計画からの準備の遅延を検出した場合、当該遅延を示す遅延情報を通信部４０１に管理システム３００へ送信させる。このとき、管理システム３００では、通信部３０１は、遅延情報を受信すると、搬送車両２０１に対して遅延情報を通知する。監視部４０３は、１回の入出庫準備に要すると推測される時間に関する指標に対する、当該入出庫準備に含まれる複数の準備工程のうち、完了した１以上の準備工程それぞれに要すると推測される時間に関する指標の積算値の割合を進捗率として算出してもよい。１回の入出庫準備とは、例えば、１台の搬送車両に対して複数の入出庫オーダがある場合に、全ての入出庫オーダにかかる荷の入出庫のための準備である。なお、ここで、１回の入出庫準備に要すると推測される時間、および、１以上の準備工程のそれぞれに要すると推測される時間は、それぞれ、予め定められた時間である。例えば、これらの時間は、１回の入出庫準備、および、１以上の準備工程のそれぞれが予め計測されることで記憶された時間であってもよい。また、１回の入出庫準備に要すると推測される時間は、入出庫準備を構成する複数の準備工程それぞれに要すると推測される時間の積算値に等しい。 When the monitoring unit 403 detects a delay in preparation from the preparation plan, the monitoring unit 403 causes the communication unit 401 to transmit delay information indicating the delay to the management system 300. At this time, in the management system 300, upon receiving the delay information, the communication unit 301 notifies the transport vehicle 201 of the delay information. The monitoring unit 403 is estimated to require one or more completed preparation steps of the plurality of preparation steps included in the entry / exit preparation for an index regarding the time estimated to be required for one entry / exit preparation. The ratio of the integrated value of the index relating to time may be calculated as the progress rate. The one-time entry / exit preparation is, for example, a preparation for entry / exit of a load related to all entry / exit orders when there are a plurality of entry / exit orders for one transport vehicle. Here, the time estimated to be required for one entry / exit preparation and the time estimated to be required for each of one or more preparation steps are predetermined times, respectively. For example, these times may be times that are stored by being measured in advance for each entry / exit preparation and one or more preparation steps. Further, the time estimated to be required for one entry / exit preparation is equal to the integrated value of the time estimated to be required for each of a plurality of preparation steps constituting the entry / exit preparation.
　監視部４０３は、進捗率を定期的に更新する。監視部４０３は、例えば、算出した進捗率が増加する変化率を算出し、算出した変化率に基づいて進捗率が１００％になるまでに要する時間を予測することで、入出庫準備が完了する時刻を予測してもよい。監視部４０３は、入出庫準備が完了する時刻が、第一到着予定情報に基づく搬送車両２０１が物流倉庫４００に到着する到着予定時刻よりも後の時刻であることを検出することで、準備計画からの準備の遅延を検出する。 (4) The monitoring unit 403 periodically updates the progress rate. The monitoring unit 403 calculates the change rate at which the calculated progress rate increases, and predicts the time required for the progress rate to reach 100% based on the calculated change rate, thereby completing the entry / exit preparation. The time may be predicted. The monitoring unit 403 detects that the time at which the entry / exit preparation is completed is later than the estimated arrival time at which the transport vehicle 201 arrives at the distribution warehouse 400 based on the first arrival schedule information, and thus the preparation plan is determined. Detect delay in preparation from.
　時間に関する指標とは、時間であってもよいし、基準となる工程であってもよい。基準となる工程を時間に関する指標とする場合、例えば、第１の工程を基準としたとき、第２の工程に第１の工程の２倍の時間を要する場合、第２の工程は第１の工程が２工程分の工程であるとすることができる。 指標 The index relating to time may be time or a reference step. When the reference step is used as an index relating to time, for example, when the second step requires twice as long as the first step when the first step is used as the reference, the second step is performed according to the first step. The process may be a process for two processes.
　遅延情報は、搬送車両２０１の到着を物流倉庫４００が受け入れ可能な時間を含んでいてもよい。また、遅延情報は、位置検出部１０４により検出されている搬送車両２０１の現在位置から所定の距離以内にある他の物流倉庫を含んでいてもよい。また、遅延情報は、第一到着予定情報に基づく搬送車両２０１が物流倉庫４００に到着する到着予定時刻から、監視部４０３が検出した遅延による入出庫準備が完了するまでにかかると予測される遅延時間を含んでいてもよい。 The delay information may include a time when the distribution warehouse 400 can accept the arrival of the transport vehicle 201. Further, the delay information may include other distribution warehouses within a predetermined distance from the current position of the transport vehicle 201 detected by the position detection unit 104. Further, the delay information is a delay predicted from the scheduled arrival time at which the transport vehicle 201 arrives at the distribution warehouse 400 based on the first scheduled arrival information to the completion of the entrance / exit preparation due to the delay detected by the monitoring unit 403. It may include time.
　なお、制御部４０２および監視部４０３のそれぞれは、例えば、プロセッサ、および、所定のプログラムを記憶しているメモリなどにより実現される。なお、制御部４０２および監視部４０３のそれぞれは、共通のプロセッサおよびメモリにより構成されていてもよいし、独立したプロセッサおよびメモリにより構成されていてもよい。 Each of the control unit 402 and the monitoring unit 403 is realized by, for example, a processor and a memory storing a predetermined program. Each of the control unit 402 and the monitoring unit 403 may be configured by a common processor and a memory, or may be configured by an independent processor and a memory.
　［３．動作］
　次に、物流システム１０の動作について図３を用いて説明する。また、動作の説明において、図４～図１１の具体例を挙げながら説明する。 [3. motion]
Next, the operation of the distribution system 10 will be described with reference to FIG. In addition, the operation will be described with reference to specific examples in FIGS.
　図３は、実施の形態にかかる物流システム１０の動作を示すシーケンス図である。 FIG. 3 is a sequence diagram illustrating an operation of the distribution system 10 according to the embodiment.
　まず、搬送車両２０１に備えられる作業端末１００では、運転手から到着先の物流倉庫を示す予定を受け付ける（Ｓ１０１）。作業端末１００は、例えば、管理システム３００から配送作業情報を受信することで予定を受け付ける。例えば、これにより、作業端末１００は、図４に示すような、配送作業情報を示す配送情報画面１１１を表示部１０５に表示する。配送情報画面１１１は、複数の物流倉庫を示す到着先と、到着先の物流倉庫に配送する配送順と、当該到着先の物流倉庫に配送または受け取りが行われたか否かを示す配送状況とがそれぞれ対応付けられて示されている。なお、作業端末１００は、運転手から直接到着先の物流倉庫を示す入力を受け付けることで予定を受け付けてもよい。 First, the work terminal 100 provided in the transport vehicle 201 receives a schedule indicating the destination distribution warehouse from the driver (S101). The work terminal 100 receives a schedule by receiving delivery work information from the management system 300, for example. For example, thereby, the work terminal 100 displays a delivery information screen 111 indicating delivery work information on the display unit 105 as shown in FIG. The delivery information screen 111 includes an arrival destination indicating a plurality of distribution warehouses, a delivery order for delivery to the destination distribution warehouse, and a delivery status indicating whether delivery or reception has been performed to the destination distribution warehouse. Each is shown in association with each other. The work terminal 100 may receive the schedule by directly receiving an input indicating the destination distribution warehouse from the driver.
　次に、搬送車両２０１の作業端末１００は、搬送車両２０１の現在位置を検出し、検出した現在位置を示す位置情報を管理システム３００に送信する（Ｓ１０２）。作業端末１００は、所定の期間毎に位置情報と搬送車両ＩＤとを管理システム３００に繰り返し送信する。 Next, the work terminal 100 of the transport vehicle 201 detects the current position of the transport vehicle 201, and transmits position information indicating the detected current position to the management system 300 (S102). The work terminal 100 repeatedly transmits the position information and the transport vehicle ID to the management system 300 every predetermined period.
　管理システム３００は、位置情報を受信し、受信した位置情報が示す搬送車両２０１の現在位置が所定範囲内にあるか否かを判定する（Ｓ１０３）。 The management system 300 receives the position information and determines whether or not the current position of the transport vehicle 201 indicated by the received position information is within a predetermined range (S103).
　管理システム３００は、搬送車両２０１の現在位置が所定範囲内にあると判定した場合（Ｓ１０３でＹｅｓ）、所定範囲内に搬送車両２０１が位置することを示す情報、および、許可情報を搬送車両２０１に送信する（Ｓ１０４）。 When the management system 300 determines that the current position of the transport vehicle 201 is within the predetermined range (Yes in S103), the management system 300 transmits information indicating that the transport vehicle 201 is located within the predetermined range and permission information to the transport vehicle 201. (S104).
　一方で、管理システム３００は、搬送車両２０１の現在位置が所定範囲内にないと判定した場合（Ｓ１０３でＮｏ）、繰り返し行われるステップＳ１０２で検出された位置情報が示す位置がステップＳ１０３で所定範囲内にあると判定されるまでステップＳ１０３を繰り返す。 On the other hand, when the management system 300 determines that the current position of the transport vehicle 201 is not within the predetermined range (No in S103), the position indicated by the position information detected in step S102 that is repeatedly performed is determined in step S103. Step S103 is repeated until it is determined that it is within the range.
　図５を用いてこの処理の具体例について説明する。図５は、搬送車両の現在位置と複数の物流倉庫の位置５０１、５０２との位置関係を示す地図５００を示す概略図である。 A specific example of this processing will be described with reference to FIG. FIG. 5 is a schematic diagram showing a map 500 showing the positional relationship between the current position of the transport vehicle and the positions 501 and 502 of a plurality of distribution warehouses.
　図５では、地図５００では、搬送車両２０１の過去の位置５２１と現在の位置５２２と、物流倉庫４００の位置５０１と、他の物流倉庫の位置５０２と、所定範囲５１１と、所定範囲５１２とが示されている。所定範囲５１１は、位置５０１を基準とした半径Ｒ１の円で規定される範囲である。所定範囲５１２は、位置５０２を基準とした半径Ｒ１の円で規定される範囲である。なお、所定範囲５１１、５１２は、半径Ｒ１の円で規定される範囲に限らずに、基準となる位置からの経路（道路）における距離に応じて規定される範囲であってもよいし、道路に沿った形状で規定される範囲であってもよい。また、所定範囲５１１、５１２の大きさは、搬送車両および／または物流倉庫に割り当てられている荷の数に応じて変更されてもよい。例えば、所定範囲５１１、５１２の大きさは、荷の数が多くなるほど大きくなるように変更されてもよい。 In FIG. 5, in the map 500, the past position 521 and the current position 522 of the transportation vehicle 201, the position 501 of the distribution warehouse 400, the position 502 of another distribution warehouse, the predetermined range 511, and the predetermined range 512 are included. It is shown. The predetermined range 511 is a range defined by a circle having a radius R1 based on the position 501. The predetermined range 512 is a range defined by a circle having a radius R1 based on the position 502. The predetermined ranges 511 and 512 are not limited to the range defined by the circle having the radius R1, but may be a range defined according to a distance on a route (road) from a reference position. May be in the range defined by the shape along. Further, the size of the predetermined ranges 511 and 512 may be changed according to the number of loads assigned to the transport vehicle and / or the distribution warehouse. For example, the size of the predetermined ranges 511 and 512 may be changed so as to increase as the number of loads increases.
　例えば、管理システム３００は、位置５２１に搬送車両２０１が位置する場合、目的地である物流倉庫４００の位置５０１を基準とする所定範囲５１１内に位置５２１がないため、ステップＳ１０３でＮｏと判定する。一方で、管理システム３００は、搬送車両２０１が移動することで物流倉庫４００に近づいて位置５２２に位置する場合、所定範囲５１１内に位置５２２があるため、ステップＳ１０３でＹｅｓと判定する。これにより、管理システム３００は、所定範囲５１１内に搬送車両２０１が位置したことを示す情報と、許可情報とを搬送車両２０１の作業端末１００に送信する。 For example, when the transport vehicle 201 is located at the position 521, the management system 300 determines No in step S103 because there is no position 521 within the predetermined range 511 based on the position 501 of the distribution warehouse 400 as the destination. . On the other hand, when the transport vehicle 201 moves and moves to the distribution warehouse 400 and is located at the position 522, the management system 300 determines Yes in step S103 because the position 522 is within the predetermined range 511. Accordingly, the management system 300 transmits information indicating that the transport vehicle 201 is located within the predetermined range 511 and permission information to the work terminal 100 of the transport vehicle 201.
　これにより、作業端末１００は、図６に示すように、物流倉庫４００に近づいたことを示す情報と共に、第一到着予定情報の送信が許可されたことを示す予約可能画面１１２を表示部１０５に表示する（Ｓ１０５）。 As a result, as shown in FIG. 6, the work terminal 100 displays, on the display unit 105, the reservable screen 112 indicating that the transmission of the first arrival schedule information is permitted, together with the information indicating that the distribution warehouse 400 is approached. It is displayed (S105).
　以下、図６～図９を用いて作業端末１００に表示される、第一到着予定情報を送信するためのＧＵＩの一例について説明する。 Hereinafter, an example of a GUI for transmitting the first arrival schedule information displayed on the work terminal 100 will be described with reference to FIGS. 6 to 9.
　図６は、実施の形態に係る予約可能画面の一例を示す図である。作業端末１００は、ＧＵＩとして予約可能画面１１２を表示部１０５に表示することで、最初または次の到着先である物流倉庫４００のバースの予約が可能となる。つまり、作業端末１００は、第一到着予定情報を送信するための入力を受け付けるＧＵＩを表示することが可能となる。 FIG. 6 is a diagram showing an example of a reservation available screen according to the embodiment. The work terminal 100 displays the reservation possible screen 112 as a GUI on the display unit 105, so that the berth of the distribution warehouse 400 as the first or next destination can be reserved. That is, the work terminal 100 can display a GUI for receiving an input for transmitting the first arrival schedule information.
　予約可能画面１１２において、「予約する」ボタンが押されると、作業端末１００は、図７に示すように、予約時間帯を選択する時間帯選択画面１１３を表示部１０５に表示する。図７は、実施の形態に係る時間帯選択画面の一例を示す図である。 When the “Reserve” button is pressed on the reservation-possible screen 112, the work terminal 100 displays a time slot selection screen 113 for selecting a reservation time slot on the display unit 105, as shown in FIG. FIG. 7 is a diagram showing an example of a time zone selection screen according to the embodiment.
　なお、時間帯選択画面１１３では、バース予約の受付が可能な時間帯のみが提示されている画面としてもよい。つまり、作業端末１００は、時間帯選択画面１１３を表示部１０５に表示する場合に、事前に管理システム３００と通信することで、物流倉庫４００に対する物流倉庫４００が備える複数のバースそれぞれの予約状況を確認し、まだ予約状況において予約されていない時間帯を提示するようにしてもよい。なお、バースが入庫用のバース、出庫用のバース、荷物の種類が予め定められているバースなど特定の条件毎にバースが予め振り分けられている場合には、搬送車両２０１の配送予定と特定の条件が合致するバースの中から予約されていないバースがある時間帯が提示されてもよい。 In addition, the time zone selection screen 113 may be a screen in which only the time zone in which the berth reservation can be accepted is presented. In other words, when displaying the time zone selection screen 113 on the display unit 105, the work terminal 100 communicates with the management system 300 in advance to display the reservation status of each of the plurality of berths of the distribution warehouse 400 with respect to the distribution warehouse 400. After confirmation, a time zone that has not been reserved in the reservation status may be presented. When berths are sorted in advance for each specific condition, such as a berth for entry, a berth for exit, and a berth in which the type of luggage is predetermined, when the berth is sorted in advance for a delivery schedule of the transport vehicle 201, A time zone in which there is a berth that is not reserved among berths that match the conditions may be presented.
　そして、時間帯選択画面１１３において複数の時間帯の中から１つの時間帯が選択されると、作業端末１００は、図８に示すように、選択された時間帯で確定するための確定画面１１４を表示部１０５に表示する。図８は、実施の形態に係る確定画面の一例を示す図である。 Then, when one time zone is selected from a plurality of time zones on the time zone selection screen 113, the work terminal 100 displays a determination screen 114 for determining the selected time zone as shown in FIG. Is displayed on the display unit 105. FIG. 8 is a diagram illustrating an example of the confirmation screen according to the embodiment.
　その後、確定画面１１４において「確定する」ボタンが押されると、作業端末１００は、図９に示すように、予約が選択された時間帯で確定されたことを示す情報と、予約されたバースの番号を示すバース番号とが示された確認画面１１５を表示部１０５に表示する。図９は、実施の形態に係る確認画面の一例を示す図である。 Thereafter, when the “confirm” button is pressed on the confirmation screen 114, the work terminal 100 displays information indicating that the reservation has been confirmed in the selected time zone and information on the reserved berth, as shown in FIG. A confirmation screen 115 showing the berth number indicating the number is displayed on the display unit 105. FIG. 9 is a diagram illustrating an example of the confirmation screen according to the embodiment.
　このとき、作業端末１００は、図６～図９での説明でなされた入力に基づいて、物流倉庫４００に「１３：００～１４：００」の時間帯に到着する予定であることを示す情報を第一到着予定情報として送信する（Ｓ１０６）。最後に、作業端末１００は、確認画面１１５において「ＯＫ」ボタンが押されると、第一到着予定情報を受け付けるためのＧＵＩの表示を終了する。 At this time, information indicating that the work terminal 100 is scheduled to arrive at the distribution warehouse 400 in the time zone of “13:00 to 14:00” based on the input made in the description of FIGS. 6 to 9. Is transmitted as first arrival schedule information (S106). Finally, when the “OK” button is pressed on the confirmation screen 115, the work terminal 100 ends the display of the GUI for receiving the first arrival schedule information.
　なお、搬送車両２０１が複数の物流倉庫４００の位置を基準とする複数の所定範囲内に位置した場合、つまり、複数の物流倉庫４００のそれぞれに対応する複数の所定範囲で共通する範囲内に位置した場合、作業端末１００は、複数の物流倉庫４００に対してそれぞれ第一到着予定情報を送信することができる。この場合、例えば、図１０に示す予約一覧画面１１６のように、作業端末１００は、第一到着予定情報を送信することにより予約が完了した画面の一覧を表示部１０５に表示してもよい。図１０は、実施の形態に係る予約一覧画面の一例を示す図である。 When the transport vehicle 201 is located in a plurality of predetermined ranges based on the positions of the plurality of distribution warehouses 400, that is, in a range common to the plurality of predetermined ranges corresponding to the plurality of distribution warehouses 400, respectively. In this case, the work terminal 100 can transmit the first arrival schedule information to each of the plurality of distribution warehouses 400. In this case, for example, like the reservation list screen 116 shown in FIG. 10, the work terminal 100 may display a list of screens for which reservation has been completed by transmitting the first arrival schedule information on the display unit 105. FIG. 10 is a diagram showing an example of a reservation list screen according to the embodiment.
　なお、図４の配送情報画面１１１のうちの１つがタッチにより選択された場合、作業端末１００は、図１１に示す予約画面１１７を表示部１０５に表示してもよい。図１１は、実施の形態に係る予約画面の一例を示す図である。 When one of the delivery information screens 111 in FIG. 4 is selected by touch, the work terminal 100 may display the reservation screen 117 shown in FIG. FIG. 11 is a diagram illustrating an example of a reservation screen according to the embodiment.
　作業端末１００は、配送情報画面１１１のうちの１つがタッチにより選択された場合、所定範囲５１１内に搬送車両２０１が位置する場合に予約画面１１７を表示部１０５表示させ、所定範囲５１１内に搬送車両２０１が位置しない場合に予約画面１１７を表示部１０５に表示させないようにしてもよい。また、作業端末１００は、所定範囲５１１内に位置するまたは位置しないにかかわらず、予約画面１１７を表示部１０５に表示させてもよい。この場合、作業端末１００は、所定範囲５１１内に搬送車両２０１が位置する場合に予約画面１１７において「バース予約」ボタンへの入力を受け付け、所定範囲５１１内に搬送車両２０１が位置しない場合に予約画面１１７において「バース予約」ボタンへの入力を受け付けないように制御してもよい。作業端末１００は、「バース予約」ボタンへの入力を受け付けない場合、「バース予約」ボタンを表示しなくてもよいし、グレーアウトさせて表示してもよい。 When one of the delivery information screens 111 is selected by touch, the work terminal 100 displays the reservation screen 117 on the display unit 105 when the transport vehicle 201 is located within the predetermined range 511, and transports the vehicle within the predetermined range 511. The reservation screen 117 may not be displayed on the display unit 105 when the vehicle 201 is not located. The work terminal 100 may display the reservation screen 117 on the display unit 105 regardless of whether or not the work terminal 100 is located within the predetermined range 511. In this case, the work terminal 100 accepts an input to the “berth reservation” button on the reservation screen 117 when the transport vehicle 201 is located within the predetermined range 511, and makes a reservation when the transport vehicle 201 is not located within the predetermined range 511. The screen 117 may be controlled so as not to receive an input to the “berth reservation” button. When the work terminal 100 does not receive an input to the “berth reservation” button, the work terminal 100 may not display the “berth reservation” button, or may display it in a grayed out manner.
　管理システム３００は、第一到着予定情報を受信すると、取得した第一到着予定情報に基づき物流倉庫４００における荷の入出庫準備の計画である準備計画を生成する（Ｓ１０７）。 When the first arrival schedule information is received, the management system 300 generates a preparation plan, which is a plan for loading and unloading the cargo in the distribution warehouse 400, based on the acquired first arrival schedule information (S107).
　そして、管理システム３００は、生成した準備計画に従って入出庫準備を物流倉庫４００に指示するために、入出庫準備の指示を示す指示情報を物流倉庫４００に送信する（Ｓ１０８）。 Then, in order to instruct the distribution warehouse 400 to perform the entry / exit preparation in accordance with the generated preparation plan, the management system 300 transmits instruction information indicating the instruction of the entry / exit preparation to the distribution warehouse 400 (S108).
　物流倉庫４００は、受信された指示情報に基づいて、物流倉庫４００における入出庫準備を開始する（Ｓ１０９）。 (5) The distribution warehouse 400 starts preparations for entering and leaving the distribution warehouse 400 based on the received instruction information (S109).
　物流倉庫４００は、物流倉庫４００における準備計画の進捗を監視し（Ｓ１１０）、準備計画からの準備の遅延があるか否かを検出する（Ｓ１１１）。 The distribution warehouse 400 monitors the progress of the preparation plan in the distribution warehouse 400 (S110), and detects whether there is a delay in preparation from the preparation plan (S111).
　物流倉庫４００は、準備計画からの準備の遅延を検出した場合（Ｓ１１１でＹｅｓ）、遅延情報を管理システム３００に送信する（Ｓ１１２）。 If the distribution warehouse 400 detects a delay in preparation from the preparation plan (Yes in S111), the distribution warehouse 400 transmits the delay information to the management system 300 (S112).
　一方で、物流倉庫４００は、準備計画からの準備の遅延を検出していない場合（Ｓ１１１でＮｏ）、ステップＳ１１０の進捗の監視を入出庫準備が完了するまで繰り返す。なお、入出庫準備が遅延無く完了した場合、処理を終了する。 On the other hand, if the distribution warehouse 400 has not detected a delay in preparation from the preparation plan (No in S111), the progress monitoring in step S110 is repeated until the entry / exit preparation is completed. If the entry / exit preparation is completed without delay, the process ends.
　管理システム３００は、遅延情報を受信すると、遅延情報を搬送車両２０１に送信することで通知する（Ｓ１１３）。 (4) Upon receiving the delay information, the management system 300 notifies the transport vehicle 201 by transmitting the delay information (S113).
　作業端末１００は、遅延情報を受信すると、図１２に示すように、遅延情報を示す遅延通知画面１１８を表示することで遅延情報を出力する（Ｓ１１４）。なお、作業端末１００は、遅延情報を音声で出力してもよい。図１２は、実施の形態に係る遅延通知画面の一例を示す図である。 When receiving the delay information, the work terminal 100 outputs the delay information by displaying the delay notification screen 118 indicating the delay information as shown in FIG. 12 (S114). The work terminal 100 may output the delay information by voice. FIG. 12 is a diagram illustrating an example of the delay notification screen according to the embodiment.
　遅延通知画面１１８は、準備計画からの準備の遅延が発生していることを示す情報、到着予定時刻からどのくらい遅れているかを示す遅延時間、到着予定時刻、バース予約の時間帯、予約したバースにおける荷下ろしまたは荷積みの作業が行われる作業時間帯などを含んでいる。なお、作業時間帯は、遅延時間がない場合、バース予約の時間帯に一致し、遅延時間がある場合、バース予約の時間帯から遅延時間に応じた時間帯だけずらした時間帯となる。遅延通知画面１１８は、図示している他にも、搬送車両２０１の到着を物流倉庫４００が受け入れ可能な時間を含んでいてもよいし、位置検出部１０４により検出されている搬送車両２０１の現在位置から所定の距離以内にある他の物流倉庫を含んでいてもよい。他の物流倉庫としては、図５の状況の場合には、地図５００の位置５０２で示される物流倉庫が配送情報に含まれる場合、当該物流倉庫への配送を優先させることを促す情報が提示されてもよい。作業端末１００は、遅延通知画面１１８において「変更する」ボタンへの入力を受け付けると、バース予約の時間帯の変更を受け付ける。また、作業端末１００は、遅延通知画面１１８において「キャンセル」ボタンへの入力を受け付けると、バース予約のキャンセルを受け付ける。 The delay notification screen 118 includes information indicating that a preparation delay from the preparation plan has occurred, a delay time indicating how far behind the estimated arrival time, an estimated arrival time, a berth reservation time zone, It includes the working hours during which the unloading or loading work is performed. If there is no delay time, the work time zone coincides with the berth reservation time zone. If there is a delay time, the work time zone is shifted from the berth reservation time zone by a time zone corresponding to the delay time. In addition to the illustration, the delay notification screen 118 may include a time during which the distribution warehouse 400 can accept the arrival of the transport vehicle 201, or the current time of the transport vehicle 201 detected by the position detection unit 104. Other distribution warehouses within a predetermined distance from the location may be included. As other distribution warehouses, in the case of the situation of FIG. 5, when the distribution information includes the distribution warehouse indicated by the position 502 on the map 500, information prompting to give priority to delivery to the distribution warehouse is presented. You may. When accepting an input to the “change” button on the delay notification screen 118, the work terminal 100 accepts a change in the berth reservation time zone. Further, when accepting an input to the “cancel” button on delay notification screen 118, work terminal 100 accepts the cancellation of the berth reservation.
　また、作業端末１００は、図１３に示すように、バース予約の変更またはキャンセルを受け付けるための予約変更画面１１９を表示部１０５に表示してもよい。図１３は、実施の形態に係る予約変更画面の一例を示す図である。 The work terminal 100 may also display a reservation change screen 119 for accepting a change or cancellation of the berth reservation on the display unit 105 as shown in FIG. FIG. 13 is a diagram showing an example of a reservation change screen according to the embodiment.
　図１２または図１３において「変更する」ボタンへの入力を受け付けると、作業端末１００は、図７に示すような時間帯選択画面１１３を表示部１０５に表示して、時間帯の変更を受け付けてもよい。バース予約の時間帯の変更、または、キャンセルを受け付けた場合、作業端末１００は、図１４に示すような変更理由画面１２０を表示部１０５に表示して、変更理由の入力を受け付けてもよい。図１４は、実施の形態に係る変更理由画面の一例を示す図である。 When the input to the “change” button in FIG. 12 or 13 is received, the work terminal 100 displays a time zone selection screen 113 as shown in FIG. Is also good. When a change or cancellation of the berth reservation time zone is received, the work terminal 100 may display a change reason screen 120 as shown in FIG. 14 on the display unit 105 and receive an input of the change reason. FIG. 14 is a diagram illustrating an example of a change reason screen according to the embodiment.
　次に、物流システム１０における配送振替処理を、図１５を用いて説明する。 Next, the delivery transfer processing in the distribution system 10 will be described with reference to FIG.
　図１５は、実施の形態に係る物流システムにおける配送振替処理の一例を示すシーケンス図である。 FIG. 15 is a sequence diagram illustrating an example of the transfer transfer process in the distribution system according to the embodiment.
　配送振替処理は、図３で説明した物流システム１０における動作において、管理システム３００の入出庫準備の指示（Ｓ１０８）が終了するタイミングで行われる。 (3) The delivery transfer process is performed at the timing when the instruction (S108) for the preparation for entry and exit of the management system 300 ends in the operation of the distribution system 10 described with reference to FIG.
　このとき、搬送車両２０１の作業端末１００は、搬送車両２０１の位置情報を継続して管理システム３００に繰り返し送信している（Ｓ１２１）。 At this time, the work terminal 100 of the transport vehicle 201 continuously and repeatedly transmits the position information of the transport vehicle 201 to the management system 300 (S121).
　管理システム３００は、搬送車両２０１から位置情報を受信すると、搬送車両２０１の位置に基づいて第二到着予定情報を算出する（Ｓ１２２）。 Upon receiving the position information from the transport vehicle 201, the management system 300 calculates the second arrival schedule information based on the position of the transport vehicle 201 (S122).
　管理システム３００は、第一到着予定情報および第二到着予定情報を比較して、第一到着予定情報と第二到着予定情報との間の所定の相違の有無を判定する（Ｓ１２３）。 The management system 300 compares the first arrival schedule information and the second arrival schedule information to determine whether there is a predetermined difference between the first arrival schedule information and the second arrival schedule information (S123).
　管理システム３００は、所定の相違が有ると判定した場合（Ｓ１２３でＹｅｓ）、搬送車両２０１に対して既に出庫の準備が完了している荷の中に配送予定としている荷が含まれ、かつ、搬送車両２０１よりも物流倉庫４００に早く到着する予定の第二搬送車両を検索する（Ｓ１２４）。 If the management system 300 determines that there is a predetermined difference (Yes in S123), the cargo scheduled to be delivered is included in the cargo that has already been prepared for delivery to the transport vehicle 201, and A second transport vehicle scheduled to arrive at the distribution warehouse 400 earlier than the transport vehicle 201 is searched (S124).
　一方で、管理システム３００は、所定の相違が無いと判定した場合（Ｓ１２３でＮｏ）、繰り返し行われるステップＳ１２１で検出された位置情報が示す位置に応じて繰り返し第二到着予定情報を算出し、新たに算出した第二到着予定情報と第一到着予定情報とに基づいて所定の相違が有ると判定されるまでステップＳ１２３を繰り返す。なお、所定の相違が無いと判定され続け、第一到着予定情報における当初の到着予定時刻となった場合には、ここで行われている繰り返しの処理は終了する。 On the other hand, when the management system 300 determines that there is no predetermined difference (No in S123), the management system 300 repeatedly calculates the second arrival schedule information according to the position indicated by the position information detected in step S121 which is repeatedly performed, Step S123 is repeated until it is determined that there is a predetermined difference based on the newly calculated second arrival schedule information and first arrival schedule information. If it is determined that there is no predetermined difference and the initial scheduled arrival time in the first scheduled arrival information is reached, the repetitive processing performed here ends.
　管理システム３００は、ステップＳ１２４において、第二搬送車両が有ると判定した場合（Ｓ１２４でＹｅｓ）、少なくとも一部の荷を第二搬送車両に割り当てる指示を示す割り当て情報を物流倉庫４００に送信する（Ｓ１２５）。 When it is determined in step S124 that there is a second transport vehicle (Yes in S124), the management system 300 transmits allocation information indicating an instruction to allocate at least a part of the load to the second transport vehicle to the distribution warehouse 400 ( S125).
　一方で、管理システム３００は、第二搬送車両が無いと判定した場合（Ｓ１２４でＮｏ）、処理を終了する。なお、管理システム３００は、この場合、処理を終了せずに、ステップＳ１２４の判定を繰り返し行ってもよい。管理システム３００は、ステップＳ１２４の判定を繰り返す場合において、ステップＳ１２４でＮｏと判定され続け、第一到着予定情報における当初の到着予定時刻となった場合には、ここで行われている繰り返しの処理は終了する。 On the other hand, when the management system 300 determines that there is no second transport vehicle (No in S124), the management system 300 ends the process. In this case, the management system 300 may repeat the determination in step S124 without ending the processing. When the determination in step S124 is repeated, the management system 300 continues to determine No in step S124, and when the first scheduled arrival time in the first scheduled arrival information is reached, the repetition processing performed here. Ends.
　物流倉庫４００は、割り当て情報を受信すると、割り当て情報に基づいて荷を第二搬送車両に割り当てる（Ｓ１２６）。 (4) Upon receiving the allocation information, the distribution warehouse 400 allocates the load to the second transport vehicle based on the allocation information (S126).
　図１６は、各搬送車両に物流倉庫４００において入出庫される予定の物品を示す入出庫情報の一例を示す図である。なお、図１６では、物流倉庫４００から出庫される物品についての情報が示されている。また、図１６に示す入出庫情報には含まれていないが、入出庫情報は、入出庫の作業に要すると予測される時間、および入出庫準備に要すると予測される時間が含まれていてもよい。 FIG. 16 is a diagram showing an example of entry / exit information indicating articles to be entered / exited in the distribution warehouse 400 for each transport vehicle. Note that FIG. 16 shows information on articles that are ejected from the distribution warehouse 400. Although not included in the entry / exit information shown in FIG. 16, the entry / exit information includes a time estimated to be required for the entry / exit work and a time estimated to be required for the entry / exit preparation. Is also good.
　図１６の入出庫情報の例では、搬送車両２０１は、物流倉庫４００から物品ａを３個、物品ｂを２個積み込む予定であった。このため、物流倉庫４００では、当初の到着予定時刻までに物品ａを３個と物品ｂを２個とを出庫する準備が進められていた。しかしながら、搬送車両２０１が当初の到着予定時刻よりも大幅に遅れることとなることが検出されたため、管理システム３００では、物流倉庫４００において搬送車両２０１と同じ物品ｂを２個積み込む予定の搬送車両２０２が搬送車両２０１よりも先に物流倉庫４００に到着する予定であることを特定し、搬送車両２０１のために既に準備が完了していた２個の物品ｂを搬送車両２０２に割り当てることを行う。これにより、２個の物品ｂを出庫する準備を効率よく行うことができる。 In the example of the entry / exit information in FIG. 16, the transport vehicle 201 was to load three articles a and two articles b from the distribution warehouse 400. For this reason, in the distribution warehouse 400, preparations for unloading three articles a and two articles b by the originally scheduled arrival time have been made. However, since it has been detected that the transport vehicle 201 is significantly delayed from the initial scheduled arrival time, the management system 300 determines that the transport vehicle 202 that is to load the same two articles b as the transport vehicle 201 in the distribution warehouse 400. Is determined to arrive at the distribution warehouse 400 before the transport vehicle 201, and the two articles b that have already been prepared for the transport vehicle 201 are assigned to the transport vehicle 202. This makes it possible to efficiently prepare for releasing the two articles b.
　［４．効果など］
　本実施の形態に係る物流システム１０によれば、物流倉庫４００に到着予定の搬送車両２０１からの第一到着予定情報に基づく準備計画が遅延している場合に、搬送車両２０１に対して遅延情報を通知することで、搬送車両２０１の運転手に、物流倉庫４００の搬送車両２０１に対する準備が遅延していることを知らせることができる。これにより、例えば、運転手に、準備計画からの準備の遅延を考慮して物流倉庫４００に到着するまでの時間を有効に使うことを促すことができる。よって、物流倉庫４００において搬送車両２０１が待機する時間を低減することができ、物流倉庫４００において待機する搬送車両の数を低減することができる。 [4. Effects etc.]

Therefore, the time during which the transport vehicle 201 waits in the distribution warehouse 400 can be reduced, and the number of transport vehicles waiting in the distribution warehouse 400 can be reduced.
　また、本実施の形態に係る物流システム１０において、搬送車両２０１が物流倉庫４００の位置５０１を基準とした所定範囲５１１内に位置することが位置検出部１０４により検出されると、（ｉ）管理システム３００は、所定範囲５１１内に搬送車両２０１が位置することを搬送車両２０１の作業端末１００に通知し、（ｉｉ）送信制御部３０３は、作業端末１００による第一到着予定情報の送信を許可する。 In the distribution system 10 according to the present embodiment, when the position detection unit 104 detects that the transport vehicle 201 is located within the predetermined range 511 based on the position 501 of the distribution warehouse 400, (i) management The system 300 notifies the work terminal 100 of the transport vehicle 201 that the transport vehicle 201 is located within the predetermined range 511, and (ii) the transmission control unit 303 permits the work terminal 100 to transmit the first arrival schedule information. I do.
　これによれば、搬送車両２０１が物流倉庫４００の所定範囲５１１内まで近づいた段階で、搬送車両２０１の作業端末１００における第一到着予定情報の送信を許可するため、物流倉庫４００は、搬送車両２０１のより精度のよい到着予定時刻を、取得することができる。このため、搬送車両２０１に対する準備が完了するまでの時刻を、搬送車両２０１の到着予定時刻に精度よく合わせることができる。よって、搬送車両２０１が物流倉庫４００において待機する時間を低減することができる。また、物流倉庫４００で準備が完了した荷をすぐに搬送車両２０１に移載する作業を開始できるため、物流倉庫４００内で準備が完了した荷物を載置しておくスペースを削減することができる。 According to this, when the transport vehicle 201 approaches the predetermined range 511 of the distribution warehouse 400, the transmission terminal 400 permits the transmission of the first arrival schedule information at the work terminal 100 of the transport vehicle 201. It is possible to acquire a more accurate estimated arrival time of the server 201. Therefore, the time until the preparation for the transport vehicle 201 is completed can be accurately adjusted to the estimated arrival time of the transport vehicle 201. Therefore, the time during which the transport vehicle 201 waits in the distribution warehouse 400 can be reduced. In addition, since the operation of immediately transferring the prepared cargo to the transport vehicle 201 in the distribution warehouse 400 can be started, the space for storing the prepared cargo in the distribution warehouse 400 can be reduced. .
　また、本実施の形態に係る物流システム１０において、搬送車両２０１が物流倉庫４００に第一到着予定情報による到着予定よりも、搬送車両２０１の現在位置に基づく物流倉庫４００への到着予定が遅くなると判定された場合、物流倉庫４００において搬送車両２０１のための出庫の準備が完了している荷のうちの少なくとも一部を、搬送車両２０１よりも物流倉庫４００に早く到着する予定の搬送車両２０２の準備品として割り当てる。このため、搬送車両２０１のための出庫の準備が完了している荷の少なくとも一部を、搬送車両２０１が到着しなくても搬送車両２０２が到着すれば搬送車両２０２に移載する作業を開始することができる。よって、搬送車両２０１、２０２の位置に応じて、準備が完了している荷を搬送させる搬送車両の割り当てを変更することで、出庫の準備を効率よく行うことができる。 Further, in the distribution system 10 according to the present embodiment, when the transportation vehicle 201 arrives at the distribution warehouse 400 based on the current position of the transportation vehicle 201 later than the arrival schedule based on the first arrival schedule information, at the distribution warehouse 400. When it is determined, at least a part of the load that is ready for delivery for the transport vehicle 201 in the distribution warehouse 400 is transferred to the transport vehicle 202 that is to arrive at the distribution warehouse 400 earlier than the transport vehicle 201. Assign as supplies. For this reason, the operation of transferring at least a part of the load, which is ready for delivery for the transport vehicle 201, to the transport vehicle 202 when the transport vehicle 202 arrives even if the transport vehicle 201 does not arrive, is started. can do. Therefore, by changing the assignment of the transport vehicles for transporting the ready-prepared load according to the positions of the transport vehicles 201 and 202, it is possible to efficiently perform the preparation for leaving the warehouse.
　また、本実施の形態に係る物流システム１０において、遅延情報は、搬送車両２０１の到着を物流倉庫４００が受け入れ可能な時間を含む。このため、搬送車両２０１の運転手に、受け入れ可能な時間までの時間を有効に使うことを促すことができ、物流倉庫４００において搬送車両２０１が待機する時間を低減することができる。 In the distribution system 10 according to the present embodiment, the delay information includes a time when the distribution warehouse 400 can accept the arrival of the transport vehicle 201. Therefore, it is possible to encourage the driver of the transport vehicle 201 to effectively use the time up to an acceptable time, and it is possible to reduce the waiting time of the transport vehicle 201 in the distribution warehouse 400.
　また、本実施の形態に係る物流システム１０において、遅延情報は、位置検出部１０４により検出されている搬送車両２０１の現在位置から所定の距離以内にある他の物流倉庫を含む。このため、搬送車両２０１の運転手に、搬送車両２０１の近くにある他の物流倉庫に行くことを優先させることを促すことができ、物流倉庫４００において搬送車両２０１が待機する時間を低減することができる。 In the distribution system 10 according to the present embodiment, the delay information includes another distribution warehouse located within a predetermined distance from the current position of the transport vehicle 201 detected by the position detection unit 104. For this reason, it is possible to encourage the driver of the transport vehicle 201 to give priority to going to another distribution warehouse near the transport vehicle 201, and to reduce the waiting time of the transport vehicle 201 in the distribution warehouse 400. Can be.
　また、本実施の形態に係る物流システム１０において、遅延情報は、第一到着予定情報に基づく搬送車両２０１が物流倉庫４００に到着する到着予定時刻から、遅延による準備が完了するまでにかかると予測される遅延時間を含む。このため、搬送車両２０１の運転手に、物流倉庫４００が受け入れ可能となるまでにかかる時間を知らせることができるため、受け入れ可能な時間までの時間を有効に使うことを促すことができ、物流倉庫４００において搬送車両２０１が待機する時間を低減することができる。 Further, in the distribution system 10 according to the present embodiment, the delay information is predicted to be from the scheduled arrival time at which the transport vehicle 201 arrives at the distribution warehouse 400 based on the first scheduled arrival information until the preparation due to the delay is completed. Including delay time. For this reason, the driver of the transport vehicle 201 can be notified of the time required until the distribution warehouse 400 becomes acceptable, so that it is possible to encourage the effective use of the time up to the acceptable time.

　［５．変形例］
　上記実施の形態では、判定部３０５は、当初の到着予定時刻の所定時間後の時刻よりも早く到着する場合、所定の相違がないと判定するとしたが、これに限らない。判定部３０５は、この場合、当初の到着予定時刻よりも所定時間（例えば１０分間）以上早く到着する場合、所定の相違が有ると判定し、当初の所定到着予定時刻の前後それぞれから所定時間の時間範囲で到着する場合、所定の相違がないと判定してもよい。判定部３０５は、判定結果を制御部３０２に出力する。 [5. Modification]
In the above embodiment, the determination unit 305 determines that there is no predetermined difference when arriving earlier than a predetermined time after the initial estimated time of arrival, but this is not a limitation. In this case, when arriving at least a predetermined time (for example, 10 minutes) earlier than the originally scheduled arrival time, the determination unit 305 determines that there is a predetermined difference, and determines the predetermined time from before and after each of the initially predetermined scheduled arrival time. When arriving in the time range, it may be determined that there is no predetermined difference. The determination unit 305 outputs a determination result to the control unit 302.
　制御部３０２は、判定部３０５から判定結果を取得し、判定部３０５により所定の相違が有ると判定されると、搬送車両２０１が配送予定としている荷であって、搬送車両２０１よりも遅く物流倉庫４００に到着する予定の第二搬送車両に対して既に出庫の準備が完了している荷を検索する。具体的には、管理システム３００では、複数の搬送車両のそれぞれから第一到着予定情報を取得しているため、第一到着予定情報に含まれる入出庫情報に基づいて、搬送車両２０１が配送予定としている荷であって、搬送車両２０１よりも遅く物流倉庫４００に到着する予定の第二搬送車両（例えば、搬送車両２０２）に対して既に出庫の準備が完了している荷を特定することができる。また、管理システム３００では、複数の搬送車両のそれぞれから位置情報を取得しているため、複数の搬送車両のそれぞれについて、当該搬送車両が現在位置から物流倉庫４００までの移動に要する時間を算出することで、当該搬送車両の第二到着予定情報を算出することができる。よって、管理システム３００では、搬送車両２０１よりも物流倉庫４００に遅く到着する予定の搬送車両２０２を検索することができる。制御部３０２は、搬送車両２０１が配送予定としている荷であって、搬送車両２０１よりも遅く物流倉庫４００に到着する予定の第二搬送車両に対して既に出庫の準備が完了している荷が存在する場合、当該荷を、搬送車両２０１への準備品として割り当てる。 The control unit 302 obtains the determination result from the determination unit 305, and when the determination unit 305 determines that there is a predetermined difference, the transport vehicle 201 is a load scheduled to be delivered, and the logistics is slower than the transport vehicle 201. A search is made for a load that has already been prepared for delivery to the second transport vehicle scheduled to arrive at the warehouse 400. Specifically, in the management system 300, since the first arrival schedule information is acquired from each of the plurality of transport vehicles, the transport vehicle 201 determines the delivery schedule based on the entry / exit information included in the first arrival schedule information. It is possible to specify a load that is already prepared for delivery to a second transport vehicle (for example, the transport vehicle 202) that is scheduled to arrive at the distribution warehouse 400 later than the transport vehicle 201. it can. Further, in the management system 300, since the position information is acquired from each of the plurality of transport vehicles, for each of the plurality of transport vehicles, the time required for the transport vehicle to move from the current position to the distribution warehouse 400 is calculated. Thereby, the second arrival schedule information of the transport vehicle can be calculated. Therefore, the management system 300 can search for the transport vehicles 202 scheduled to arrive at the distribution warehouse 400 later than the transport vehicles 201. The control unit 302 determines that the cargo that is scheduled to be delivered by the transport vehicle 201 and that has already been prepared for delivery to the second transport vehicle that is scheduled to arrive at the distribution warehouse 400 later than the transport vehicle 201 is If there is, the load is allocated as a preparation for the transport vehicle 201.
