For the sake of understanding, the following describes a specific flow of an embodiment of the present invention, please refer to fig. 1, and fig. 1 is a flow chart of the logistic line planning method according to the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs. The method is mainly applied to a logistics distribution system, particularly to a part of functions aiming at an operator in the system, such as a mobile phone of the operator, wherein the mobile phone is provided with APP software for receiving and dispatching orders, the APP is functional software with logistics line planning and express tracking functions, the system distributes corresponding operators according to dispatching addresses of express, and after receiving order information of the express, the APP software plans dispatching paths of the express, in the embodiment, the order information received by the APP can be orders for dispatching, or orders for picking up the express, and a specific implementation flow is as follows:
101. acquiring express mail information to be processed by a current salesman, position information of a distribution center where the current salesman is located and vehicle information of a vehicle currently available by the distribution center;
in this embodiment, the to-be-processed express mail information may be dispatch information or pickup information; in the process of collecting express mail information, the express mail information is obtained according to classes of the service staff, specifically, information of the service staff needing to carry out logistics route planning or optimization is determined firstly, for example, staff numbers corresponding to the service staff and the like can uniquely identify the service staff, then order information processed by the service staff is called from an order database through an APP according to the information of the service staff, wherein the order information can be unprocessed orders in a range before and after a current time period, and can also be all unprocessed orders related to the service staff in the database.
Further, by locating the location information of the distribution center where the service staff is located through the GPS, in practical applications, the distribution center can be understood as the starting point and the ending point of the distribution activities, which include warehouses, ports and the like with the functions of distributing, stocking and picking, and the attributes of the distribution center to be considered in the VRP problem include the geographic location, the number of available distribution vehicles and the like. Generally divided into single distribution centers and multiple distribution centers. If one distribution center is selected, the express information of the service staff can be sent from one place, and the express can be picked up without crossing different distribution centers.
The method includes the steps that vehicle information of vehicles which can be called to dispatch or pull in the distribution center at the current moment is searched based on the distribution center, and corresponding searching can be performed according to business personnel when the vehicle information is searched, for example, a logistics company provides a logistics team with a plurality of distribution vehicles, the team where the logistics company is located is determined according to the information of the business personnel when searching is performed, and then the vehicle information of vehicles which are not dispatched currently in the team is determined.
In this embodiment, when there are a plurality of determined distribution centers, vehicles of the plurality of distribution centers need to be considered when searching for available vehicles, and it is needless to say that the distribution vehicles need to be acquired from each distribution center, and the route planning process considered at this time needs to be dispatched by replacing the vehicles.
In the present embodiment, when the vehicle information is acquired, specifically, the maximum load, specification, speed, maximum travel distance, and the like of each vehicle that can be called are acquired.
102. Analyzing all express information in charge of the service staff to obtain corresponding express order information and a delivery address set, and numbering each delivery address in the delivery address set;
in the step, when the express information is analyzed, specifically, the express information is analyzed through a character and picture identification technology, the character identification technology extracts editable information in the express information, such as an address item, a remark item and the like, and the picture identification technology identifies an image and a character part in the express information through the picture identification technology when the express information belongs to a picture, and the extracted express order information includes delivery requirements of orders and delivery goods quantity of the express information; after all express information of the service staff is extracted, the extracted express addresses form an express address set, the addresses in the express address set are numbered randomly to obtain an address sequence, and finally the address sequence is used as an allowed access address list of each available vehicle.
103. The vehicle information, the order information and the dispatch address set are used as constraint conditions for logistics route planning, and a path optimization model is utilized to calculate matching parameters between the service staff and available vehicles;
in this embodiment, the path optimization model is a model obtained by training logistics history processing information through an ant colony algorithm, and when a logistics route is planned, vehicle information, order information, and a dispatch address set of available vehicles are used as initial conditions for planning the logistics route, that is, the planned route must be transported by a selected available vehicle, and an address through which the route passes is an address specified in the dispatch address set.
When the matching parameters are calculated by using the path optimization model, different vehicles are sequentially selected from available vehicles, all addresses in the dispatch address set are traversed according to the ant algorithm principle in the path optimization model to obtain a plurality of lines, then the time for transporting express mails to the dispatch addresses through the plurality of lines respectively, the path distance, the cost and other parameters are calculated, whether the parameters meet the requirements in order information and the transportation requirements of the system for the service staff is judged, and one of the plurality of lines is selected as the optimal logistics line of the vehicle based on the judgment result.
For example, the number of the selected available vehicles is 5, the dispatch address is 3, and a vehicle which can meet the transportation requirement and can also meet the dispatch requirement is selected from the 5 vehicles by using the path optimization model, and the specific implementation process may be as follows:
firstly, 5 vehicles and 3 dispatch addresses are numbered, namely { A1, A2, A3, A4, A5} and { D1, D2, D3 };
then, randomly selecting one of the { A1, A2, A3, A4 and A5} as a transport vehicle, traversing the { D1, D2 and D3} to obtain a plurality of lines, and then selecting an optimal one of the plurality of lines as a logistics line of the transport vehicle until the logistics line calculation of 5 vehicles is completed;
for example, firstly, a1 is selected to perform traversal processing on { D1, D2 and D3} to obtain a plurality of routes which are D1 → D2 → D3, D1 → D3 → D3, D3 → D1 → D2, and an optimal route is selected from the routes, wherein the optimal route can be understood as a distribution route which meets the A1 vehicle, the meeting is low in cost, the loading amount of goods and vehicles is large, and the path length is moderate, so that a matching parameter of the current distribution amount of the A1 vehicle and a service staff is obtained. After the traversal of the a1 vehicle is completed, the processing of a2, A3, a4, a5 is continued in the same manner as that of a 1. The final output matching parameters include matching parameters of 5 vehicles with respect to the attendant.
104. And planning an optimal logistics line corresponding to the salesman according to the matching parameters.
In this embodiment, when the matching parameters include matching parameters of a plurality of vehicles and the service engineer, the step further includes selecting an optimal one from the matching parameters, and planning and outputting a logistics route based on the optimal matching parameter.
In this embodiment, the step may also be that all the matching parameters of the multiple vehicles and the servicer are output to the logistics route, and then the output logistics routes are further screened to select an optimal output, and the specific screening may be performed according to the constraint conditions of the mathematical model, for example, the constraint conditions of the mathematical model are route time length, distance, cost, and transportation cargo volume, and the specific screening may be compared and considered according to the priorities in the constraint conditions, for example: and evaluating the plurality of logistics lines according to the sequence of time window > cargo capacity > distance > cost, and directly outputting the corresponding line as the optimal line after the evaluation is passed.
In this embodiment, the output logistics route includes two sections of a going route and a returning route, and the processing of ordinary express items can be placed in the going route for processing, but in practical application, the processing can be distributed in a balanced manner according to actual requirements, so that the step also includes determining the type of the express item information before outputting the optimal route, wherein the type includes picking and dispatching, if picking, the route of the returning route section is preferentially selected to be picked in a concentrated manner, and the going route is output according to the current road condition; if the dispatch is carried out, the route centralized dispatch of the output route is preferentially selected, and the return route is output according to the current road condition.
By the implementation, the express delivery route of the salesperson is planned based on the route optimization model obtained by utilizing ant colony algorithm training, and the planning optimization of the route is realized through the algorithm model.
In this embodiment, the path optimization model is obtained by training through an ant colony algorithm, and the training process is specifically shown in fig. 2.
201. Collecting delivery order information which is delivered completely from a logistics delivery system, and classifying the delivery order information;
in the step, the delivery order information comprises two orders of picking up and sending, the two orders are classified according to the salesmen, and the order of each salesmen is also distinguished by picking up and sending.
202. Initializing the classified order information to obtain a traversal address and vehicle information;
in the embodiment, the initialization refers to resolving order information, extracting the information of dispatch addresses and the information of transport vehicles, and counting the number of times each transport vehicle passes through each address.
203. Traversing all the dispatch addresses through an ant colony algorithm to obtain information left by the vehicle passing through the dispatch addresses;
204. and outputting the optimal path and the optimal path length according to the left information, and training based on the output path to obtain a path optimization model.
In this embodiment, the ant colony algorithm is an algorithm obtained by simulating the movement law of natural real ants foraging. When ants search for food, the shortest path from the food source to the ant hole can be always found, and the ant can adapt to the change of the environment, for example, when obstacles suddenly appear on the path of the ant colony foraging, the ants can quickly avoid and find other paths from the food source to the ant hole again. It is found that this is because, during the course of the ant's movement, pheromone (pheromone), which is a kind of secretion, can be released on the path that the ant passes through, and other ants can sense the existence and intensity of this substance while moving, and select the path with large pheromone amount as their own moving direction. Because more information is left over on shorter paths in the same time, more and more ants select shorter paths, which is a positive feedback phenomenon.
For the above training process, the following analysis is performed from the perspective of ants, and the specific principle is as follows:
step 1, initializing parameters, and setting related parameters: the number n of addresses required to be traversed, antsMaximum value N of iteration times of m ants in total numbermaxInitial time, pheromone tau on each pathij(0) Tau (0), pheromone chance coefficient ρ, pheromone elicitation factor α, self-elicitation factor β, total information amount Q, and the likekAnd ensures that there is no address in the table at this time.
Step 2, randomly placing m ants on n addresses, distributing one ant at most on each address, and storing the address information of the m ants in a taboo list Jk。
In practical application, m ants send n addresses, and actually, the ants send information left when vehicles pass by each address when dispatching the addresses, so that the information on the n addresses is collected after the ants complete traversal of all the addresses, and in the traversal process, after the ants complete traversal of one address, the address information needs to be stored in a taboo list, so that the situation that the ants repeatedly perform traversal operation on the addresses to influence final information collection is avoided.
In this embodiment, when an ant traverses n addresses, after completing an address traversal, and selects a next address, the ant selects the next address by calculating a probability, where the probability calculation rule is:
wherein,probability of selecting address j from address i at time t for ant k, k representing the kth ant, τij(t) denotes the pheromone concentration at the time t of the address i, j, ηijIndicating the visibility from address i to address j, LkRepresenting the total cost (or distance) of the ant k through the path through a loop (or iteration) lock,the pheromone for ant k varies from address i to address j.
Further, after a path optimization model is obtained according to historical data training, the delivery path is planned for the delivery of the courier on the same day by using the model, and a specific planning flow is shown in fig. 3 and includes the following steps:
301. acquiring express mail information to be processed by a current salesman, position information of a distribution center where the current salesman is located and vehicle information of a vehicle currently available by the distribution center;
302. analyzing all express information in charge of the service staff to obtain corresponding express order information and a delivery address set, and numbering each delivery address in the delivery address set;
303. counting the total delivery volume of the order information to be processed by the salesman;
in this embodiment, taking a dispatch order as an example, since the cargo volumes of different orders may be different, the specific cargo volume may be calculated according to weight or volume, and the load weight of a vehicle is fixed.
In this step, when counting the total delivery volume of the order of the salesman, optionally, selecting the delivery order of one day to count, firstly classifying the order, for example, if the order is a file type small express, counting according to the volume; if the express items of the large items are express items, counting is carried out according to the volume, and after the volume weight counting is finished, the occupied volume needs to be converted into the occupied volume, so that the counting of the total delivery amount of the order information is finished.
304. Selecting at least one vehicle meeting loading requirements from the available vehicles according to the total delivery amount;
in this embodiment, the loading requirement includes a maximum load of the selected vehicle being greater than or equal to the total delivery amount; in the process of selecting the vehicle according to the total delivery volume, in addition to the loading weight of the vehicle, the method further includes considering the model of the vehicle, for example, the vehicle with the same loading volume, and selecting the vehicle with less fuel consumption.
Of course, it is also possible to choose not only vehicles with a loading weight equal to the total delivery volume, but in practice it is also necessary to leave room for the subsequent addition of delivery orders, which can be chosen by setting the fluctuation range, for example a vehicle with a loading weight of 25 kg can be chosen.
In practical application, the method can also comprise the step of selecting vehicles according to dispatch area information of a salesman, small trucks such as flat trucks can be selected for an address area with convenient traffic, and cars such as minibuses can be selected for an area with inconvenient traffic.
305. Taking the distribution center as a starting place, and traversing all the distribution addresses in the distribution address set by the at least one vehicle through the path optimization model to obtain a plurality of logistics routes;
in this embodiment, the position information of the origin of the selected at least one vehicle is set as the position information of the distribution center, and the distribution address set is traversed based on the position information by using the ant colony algorithm principle to obtain a plurality of logistics routes.

3056. when all dispatch addresses in the dispatch address set are traversed, clearing the taboo list, and planning an optimal logistics route between the salesman and the first vehicle based on all route information obtained by traversal;
3057. and selecting a second vehicle from the rest vehicles to traverse the dispatch address set, and outputting a corresponding optimal logistics route. Until all vehicle traversal plans are completed, step 306 is executed.
In practical application, after a vehicle is selected from at least one vehicle, a dispatch address is randomly selected from a dispatch address set allowed by the vehicle for traversal, namely, a route from a distribution center to the selected address is traversed through a route optimization model, namely, a route from the distribution center to the selected address is traversed through a model simulation ant, real-time driving records between the two are traversed through navigation software, the concentration of pheromones on the corresponding route is obtained through traversing the number of the vehicles between two places, so that the optimal route between the two places is calculated, in practical application, the driving records of the truck are counted preferentially during traversal, the reaction of the driving time left by the truck and the driving road conditions is obtained, the conditions of traffic and roads on the corresponding route are calculated, and an optimal section of logistics route is output, and after the output of the path is finished, taking the dispatch address as an initial point of the vehicle, selecting the next dispatch address from the rest dispatch addresses, and recombining the whole logistics route to obtain the final optimal logistics route of the vehicle after the dispatch address set is traversed.
In this step, the plurality of logistics routes that are finally output refer to an optimal logistics route set formed by traversing the dispatch address set for all vehicles selected in step 304, respectively, to obtain an optimal route for each vehicle.

In this embodiment, for the selection according to the probability, specifically, the probability that the first vehicle passes through each dispatch address is calculated according to a preset probability conversion rule, and one dispatch address with the highest probability is selected as the first dispatch address, where the probability conversion rule is as follows:
