Specifically, the warehousing task flow is shown in fig. 2-a, and includes: determining whether an idle shuttle vehicle enters and exits the warehouse buffer position and an idle storage position; if an idle shuttle vehicle in-out warehouse buffer position and an idle storage position exist, the goods elevator is transported to the shuttle vehicle in-out warehouse buffer position, and then the idle trolley is waited to be transported and warehoused to finish the warehousing task; and if only the idle shuttle vehicle is in and out of the storage buffer position or the idle storage position or both are not available, waiting for the idle shuttle vehicle to appear in and out of the storage buffer position and the idle storage position.
The ex-warehouse task flow is shown in fig. 2-B, and comprises the following steps: determining whether an idle shuttle vehicle enters or exits a warehouse buffer position; if the idle shuttle vehicle in-out storage buffer position exists, determining whether the shuttle vehicle needs to be moved, if so, moving the shuttle vehicle firstly, then waiting for the trolley to be transported to the idle shuttle vehicle in-out storage buffer position, and if not, directly waiting for the trolley to be transported to the idle shuttle vehicle in-out storage buffer position; finally, the goods are carried out of the warehouse by the goods elevator so as to complete the warehouse-out task; and if no idle buffer position exists, waiting until an idle shuttle vehicle enters or exits the warehouse buffer position.
The shuttle layer-changing task flow is shown in fig. 2-C, and comprises the following steps: when the layer where the warehousing task or the ex-warehousing task is located is empty, waiting for the appearance of an idle trolley and an idle layer-changing elevator, controlling the idle trolley to move to the tail of the roadway, controlling the layer-changing elevator to move to the layer where the idle trolley is located, and carrying the idle trolley to the layer where the warehousing task or the ex-warehousing task is located by the layer-changing elevator to complete the layer-changing task of the shuttle car.

Specifically, the warehouse entry and exit traffic may include warehouse entry and exit amount per hour, task waiting threshold time, cargo occupancy, and task average completion time. The attribute information of the shelf may include the number of shelf layers, the height of each layer, the number of rows, the width of each row, and the number of shelves. Wherein, a shuttle vehicle in-out warehouse buffer position can be arranged on the goods shelf. The warehousing equipment can comprise a goods elevator, a layer changing elevator and a shuttle car. The operational parameters of the in-out device may include one or more of: acceleration, deceleration, top speed, load time and unload time.

As an example, the simulation results may include one or more of: equipment utilization rate, task completion rate and task execution time. In an alternative embodiment, the simulation result may be displayed in the form of an icon, such as a bar chart, a pie chart, or the like.
By analyzing the simulation result, whether the number of the current system shuttle vehicles is enough, the overall processing capacity of the system and other information can be generally judged, then the warehouse layout is modified according to the problems, the warehouse simulation model is modified, and the model is operated again to obtain a new simulation result. For example, if the utilization rate of the shuttle vehicles is high and the completion rate of the warehouse entry and exit tasks is low, it is indicated that the number of the shuttle vehicles is insufficient at present, the shuttle vehicles need to be added, only the quantity parameters of the shuttle vehicles need to be modified, the modified warehouse simulation model is operated, the system operation condition under the new planning scheme can be checked again, then the system operation condition is modified according to the operation condition, and the optimal configuration number of the shuttle vehicles under the condition of meeting the flow of the vertical warehouse can be finally calculated through repeated iteration.

For step S301, determining a layout plan for the warehouse may include determining a workflow and system parameters for the warehouse. The work flow of the warehouse comprises an warehousing task flow, an ex-warehouse task flow and a shuttle vehicle layer-changing task flow (see fig. 2-a, 2-B and 2-C). Triggering a Bar Code Reader (Code Reader) on an warehousing turnover box, then generating warehousing tasks, carrying the warehousing turnover box by a goods elevator and a shuttle car to finish warehousing, when an ex-warehouse task box is positioned and generated by the ex-warehouse task, carrying the ex-warehouse turnover box out of the warehouse by the shuttle car and the goods elevator, and if the warehouse needs to be moved, moving the warehouse first and then moving the warehouse out. When the layer of the warehouse-in and warehouse-out task is empty, the idle trolley and the layer changing elevator are called to complete the layer changing of the trolley, and the trolley can start to execute the warehouse-in and warehouse-out task of the current layer. The system parameters of the warehouse include one or more of the following: the flow rate of the warehouse in and out, the attribute information of the goods shelves, the number, the position and the operation parameters of the warehouse in and out equipment. Specifically, the warehouse entry and exit traffic may include warehouse entry and exit amount per hour, task waiting threshold time, cargo occupancy, and task average completion time. The attribute information of the shelf may include the number of shelf layers, the height of each layer, the number of rows, the width of each row, and the number of shelves. Wherein, a shuttle vehicle in-out warehouse buffer position can be arranged on the goods shelf. The warehousing equipment can comprise a goods elevator, a layer changing elevator and a shuttle car. The operational parameters of the in-out device may include one or more of: acceleration, deceleration, top speed, load time and unload time.
For step S302, a warehouse simulation model may be generated according to the following steps:

(2) adding entities such as a goods elevator, a layer changing elevator, a shuttle vehicle in-out warehouse buffer position and the like according to a warehouse layout scheme, and setting the size, the position and the number of the entities;
(3) adding an in-out warehouse conveyor belt;
(4) adding each entity comprises receiving a warehousing command, a goods entering device, a goods leaving device and other events which need to be executed;
(5) setting operation parameters of each device, including acceleration, deceleration, highest speed, cargo loading time, cargo unloading time and the like;
(6) adding an interface for modifying the warehouse simulation model;
(7) and adding a simulation result display panel to facilitate observation of the operation condition of system equipment and the task completion condition.
With regard to (6) above, the process of adding an interface that modifies the warehouse simulation model may include: creating a user interface containing the settings of equipment parameters, the number of specific used equipment, the warehouse-in and warehouse-out flow demand and the like, creating data references of an input box and a warehouse simulation model entity, and after the parameters in the user interface are modified, synchronously changing the specific parameters of the equipment in the warehouse simulation model; and adding a model operation control key, wherein the model operation control key comprises a start button, a pause button and a bar button, and can drag the bar button to control the operation speed of the model, reset the model, import and export the setting and the like. The function buttons can very easily control the simulation model to run after the model setting is modified.
For (7) above, the simulation results may include one or more of: equipment utilization rate, task completion rate and task execution time. In an alternative embodiment, the simulation result may be displayed in the form of an icon, such as a bar chart, a pie chart, or the like.
By analyzing the simulation result, whether the number of the current system shuttle vehicles is enough, the overall processing capacity of the system and other information can be generally judged, then the warehouse layout is modified according to the problems, the warehouse simulation model is modified, and the model is operated again to obtain a new simulation result. For example, if the utilization rate of the shuttle vehicles is high and the completion rate of the warehouse entry and exit tasks is low, it is indicated that the number of the shuttle vehicles is insufficient at present, the shuttle vehicles need to be added, only the quantity parameters of the shuttle vehicles need to be modified, the modified warehouse simulation model is operated, the system operation condition under the new planning scheme can be checked again, then the system operation condition is modified according to the operation condition, and the optimal configuration number of the shuttle vehicles under the condition of meeting the flow of the vertical warehouse can be finally calculated through repeated iteration.
As a specific example, the task execution time may include the node times as shown in FIG. 4. Wherein, tasktype represents a task type, 1 represents an ex-warehouse task, 2 represents an in-warehouse task, and 3 represents a move-warehouse task. createTime indicates a task generation time. deadline denotes a cue time. finish time indicates the task completion time. lastTime represents the time it takes for a task to complete from production. status indicates the status of the task, 1 indicates normal completion, 2 indicates completion beyond the order taking time, and 0 indicates incomplete.
For the warehousing task, process1 represents the time from the generation of the warehousing task to the placement of the warehousing bin by the elevator into the buffer bit; for the ex-warehouse task, the process1 indicates the time from the generation of the ex-warehouse task to the start of the execution of the ex-warehouse task by the shuttle.
For the warehousing task, the process2 represents the time for the warehousing box to wait for the shuttle vehicle to execute the warehousing task in the buffer position; for the outbound task, process2 represents the time from when the shuttle starts executing the outbound task to when the outbound bin is placed in the buffer location.
For the warehousing task, the process3 represents the task time of the shuttle car from the beginning of the warehousing task to the end of putting the warehousing box on the shelf; for the outbound task, process3 represents the time the outbound bin is from entering the buffer location to the time the elevator transports it to the outbound port.
Because the whole warehouse relates to multi-device cooperative operation, the flow bottleneck is difficult to determine only by paying attention to the overall utilization rate of the devices, and the specific execution time of each task (as shown in fig. 4) is added, the flow bottleneck can be easily found out by analyzing data, and the system optimization direction can be found out.
According to analysis of a large number of simulation results, the shelf size and the number of lanes are mainly influencing the layout of the warehouse, and factors influencing the running efficiency of the equipment mainly comprise equipment speed, acceleration, loading and unloading time, flow requirements, inventory layout and the like. Thus, when the layout scheme is modified according to the simulation result, the parameters as shown in fig. 5 may be modified.
