703, implementing the logistics scheme of the selected item by using the simulation model system to obtain a simulation output result;
and step 706, taking the obtained logistics plan of the picking service as the final logistics plan of the picking service.
In step 701 of the above process, the planned warehouse logistics plan includes a logistics workflow, and the workflow includes a task flow of picking items off shelves, a full-box changing flow and a full-box line casting flow. Specifically, after a simulation model system is provided, when the simulation model system is initialized, a simulation picking person actively triggers and calls logistics task information of the WMS, simulates and obtains a destination goods position of a first goods picking task, picks the goods, triggers and calls logistics task information of the WMS again after the goods picking is completed, obtains a destination goods position of a next goods picking task, picks the goods, judges whether the picked goods are full after the goods picking is completed, triggers and calls the logistics task information of the WMS to perform full box operation if the goods are full, and otherwise, continues to execute the logistics task information triggering and calling the WMS to perform the next goods picking task. And simulating the goods picking task according to the process to obtain a simulation output result.
In step 702 of the above process, a simulation model system is provided specifically according to the following process:
a first step of adding item shelves: setting the layer height, the row width, the layer number and the row number of the goods shelves and the number of the goods shelves according to the layout of the warehouse logistics scheme;
secondly, adding a sorting coordinate net according to the layout of the warehouse logistics scheme, and setting parameters such as turning, straight lines and directions;
step three, setting a storage area and a partition physical area;
step four, adding each virtual entity comprises receiving the picking service information, sending the current position and the information of the article container, receiving the picking service information again, and finishing various information to be executed when the picking is finished and the case is full;
fifthly, setting operation parameters of each virtual entity in the simulation model system, wherein the operation parameters comprise the time for picking and loading goods, the maximum walking speed, the acceleration, the deceleration or/and the time for unloading goods and the like;
a sixth step of adding an interface for modifying the picking simulation model;
and step seven, adding a simulation output result display interface to facilitate observation of the running condition and the task completion condition of the simulation model system.
In a sixth step, adding an interface to modify the picking model may include: selecting personnel number parameterization, walking speed parameterization and shelf attribute parameterization, adding simulation model operation control keys comprising an application key and a start pause stop key, and providing a simulation model system through the response to the keys. When a certain parameter is modified, the application key is clicked to complete the updating of the simulation model system parameter.
In the seventh step, the simulation output result includes one or more of the following: whether the first operation position is consistent with the actual position or not; whether the picking trajectory is consistent with the reality; when the picking personnel change, whether the operation position distributed again is consistent with the actual position or not; and whether the work efficiency is consistent with reality, etc.
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.
