Step 705 of the above process specifically includes: and if the set planning system parameters related to simulation in the provided simulation model system are not met, the set planning system parameters related to simulation are checked back, the provided simulation model system is operated again, the process is executed again according to the process, the obtained simulation output result and the actual output result are analyzed, and the logistics scheme meeting the expected selection service is finally obtained through repeated iteration.
Executed according to the process described in fig. 7, a schematic diagram of the simulation output result of the logistics plan implementing the planned picking service shown in fig. 8 is obtained, which is a corresponding relationship between the current item capacity of the warehouse and the time value for implementing the logistics plan. In an alternative embodiment, the simulation output result may also be displayed in the form of an icon, such as a graph or a bar graph.
As a specific example, the execution time of the picking traffic may include various time nodes as shown in fig. 8. Where PersonNum is the number of people currently picking, status identifies the status of the task, 1 indicates that the picking task is not pulled down, 2 indicates the currently picking task, 3 indicates the completed picking task, and PersonDis is the picking travel distance. For the undrawn task, Queue1 represents the number of orders that have entered the order pool but have not been pulled; for the current picking task, Queue2 represents the number of orders that have been pulled from the pool of orders; for pick completion tasks, Queue3 indicates the number of orders that have been pulled from the order pool and completed the pick action. Here, since the input of the next picking task is based on the completion of the previous picking item task for the picking task of the whole warehouse, the walking distance of the picking task and the number of the current picking personnel added in the simulation model system obtain a relatively comprehensive analysis result based on the walking distance and the number of the current picking personnel, and the optimization direction of the warehouse logistics scheme is determined.
It can be seen that the reasons for the picking efficiency of the picking service of the warehouse logistics plan are the number of items picked per time and the distance traveled by the picker, which is related to the structure of the item order and the pull-down algorithm employed by the WMS. The structure of the article order belongs to the problem to be solved in the planning level, and the pull-down algorithm is a mode of disassembling and fusing the article order and issuing corresponding picking task information; the walking distance can be set through planning system parameters related to simulation in the simulation model system.
