Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0051] The terms "first", "second", "third", "fourth" and the like (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0052] The technical solutions of the present application are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

[0053] As can be seen from the background, although digital twin applications can simulate entity systems such as those with three-dimensional presentation functions or debugging functions, these solutions are all simulations of the entity systems themselves, and cannot communicate and interact with existing entity systems, and further cannot perform subsequent simulation processes based on the information of the communication and interaction.

[0054] To solve the above problems, the embodiment of the present application provides a simulation model system for implementing a planned warehouse logistics scheme. After receiving the logistics task information of the WMS, the simulation model system simulates the running of the planned warehouse logistics scheme according to the logistics task information, and obtains a simulation output result. A terminal device such as a PDA is also provided to implement the planned warehouse logistics scheme. The terminal device executes according to the received logistics task information of the WMS and the planned warehouse logistics scheme to obtain an actual execution output result. The fidelity verification result is obtained by performing fidelity verification according to the simulation output result and the actual execution output result. After the planned warehouse logistics scheme is modified according to the fidelity verification result, the above process is iterated until the fidelity verification result reaches the set fidelity threshold.

[0055] In this way, the embodiment of the present application expands the simulation function of the digital twin application through communication and interaction between the digital twin application and the WMS, and applies the digital twin application to the technical field of warehouse logistics management, and specifically implements a scheme for planning a warehouse logistics scheme based on communication and interaction information with the WMS.

[0060] Step 104, revising the planned warehouse logistics scheme according to the plausibility verification result, iterating the process of steps 101-103 until the plausibility verification result reaches the preset plausibility threshold.

[0061] It can be seen that the above method is suitable for the planning stage of the warehouse logistics scheme. In the planning stage, the planned warehouse logistics scheme is frequently revised, and the revised warehouse logistics scheme is simulated and verified until the preset target is met. Subsequently, the terminal device in the warehouse is constructed and the workflow is created based on the final planned warehouse logistics scheme, and the warehouse logistics is completed.

[0076] The following is a warehouse logistics scheme for picking goods business planning, and the terminal device is a PDA.

[0077] Figure 2 The planning method of the warehouse logistics scheme provided by the embodiment of the present application provides a planning method execution process framework, and the entire execution process includes:

[0078] Step 201, provide a simulation model system for implementing the planned warehouse logistics scheme, which includes the planned layout of the entity device in the simulation warehouse, the simulation logistics planning track, the simulation logistics work planning process, and the simulation involved planning system parameters.

[0079] Step 202, prestore a plurality of item orders in an order pool and store item related information in a warehouse storage system, the order pool provides the item orders to the WMS and the warehouse storage system provides the item related information to the WMS.

[0080] Step 203, the WMS generates logistics task information according to the received item orders and item related information and the received simulation output result.

[0081] In this step, the WMS preheats, imports the item orders in the order pool and the warehouse information in the warehouse storage system, develops a data interface and performs communication interaction.

[0082] Step 204, the WMS sends the logistics task information to the simulation model system and the PDA involved in the planned warehouse logistics scheme, the PDA executes according to the planned warehouse logistics scheme according to the received logistics task information of the WMS, obtains the actual execution output result and provides it to the simulation model system.

Here, when the logistics workflow includes a picking item unloading task flow, a full box changing box flow and a full box line throwing flow, it is specifically: when the simulation model system is provided, the simulation picking personnel initiatively triggers the logistics task information of the WMS during the initialization of the simulation model system, simulates the destination location of the first picking item task, performs the picking operation, triggers the logistics task information of the WMS again after the picking is completed, obtains the destination location of the next picking item task, performs the picking operation, and judges whether the picking item is full after completion. If full, trigger the logistics task information of the WMS to perform the full box operation, otherwise, continue to trigger the logistics task information of the WMS to perform the next picking item task. According to the above process, the simulation picking item task is simulated to obtain the simulation output result.

[0092] In step 401, the simulation model system of the warehouse logistics scheme receives logistics task information of the WMS, which includes first picking position in the warehouse, picker position information, picking article information, quantity information and position information.

[0093] Here, the logistics task information is a static input parameter, which includes warehouse storage partition, shelf parameter, picking article position coordinate and full-box delivery line coordinate, etc. The simulation model system includes dynamic input parameters, which include picking personnel quantity, picking personnel walking speed, picking article time, delivery line time and first picking binding container number time, etc.

[0094] In step 402, the simulation model system simulates the warehouse logistics scheme.

[0095] In step 403, the simulation model outputs simulation output results.

[0096] Figure 5 The method flowchart of WMS output logistics related data of the warehouse logistics scheme provided by the embodiment of the present application comprises the following specific steps:

[0097] In step 501, the WMS receives simulation output results output by the simulation model system of the warehouse logistics scheme.

[0098] In step 502, the WMS generates logistics task information according to the simulation output results, article order and article related information.

[0099] Step 503, the WMS outputs the generated logistics task information to the simulation model system, including the first picking location, the next picking location information of each picker, the picking item information and the quantity information.

[0100] Figure 6 The method flow chart for the WMS to input logistics related data according to the planned warehouse logistics scheme provided by the embodiment of the application includes the following specific steps:

[0101] Step 601, the WMS receives the item order and picking item related information, including the historical item order data, the item storage location information, the picker related information, the bin threshold of the warehouse location and the current available bin quantity of the warehouse location, etc.

[0103] Step 602, the WMS generates logistics related data according to the simulation output result and the item order and item related information.

[0104] Step 603, the WMS outputs the logistics task information.

[0105] Figure 7 The method flow chart for the WMS to implement the planned picking item logistics scheme provided by the embodiment of the application includes the following specific steps:

[0106] Step 701, a planned picking item logistics scheme is determined.

[0107] Step 702, a simulation model system is established according to the picking item logistics scheme.

[0108] Step 703, the simulation model system is used to implement the picking item logistics scheme, and a simulation output result is obtained.

[0109] Step 704, it is judged whether the simulation output result is consistent with the actual execution output result obtained by implementing the picking item logistics scheme, or whether the comparison degree of reality is greater than the set degree of reality threshold; if not, step 705 is performed; if yes, step 706 is performed.

[0110] Step 705, when the fidelity between the simulation output result and the actual execution output result is large, modifying the logistics scheme of the picking service according to the simulation output result, and re-establishing a simulation model system based on the modified logistics scheme of the picking service, returning to step 703 for continuous execution until the fidelity is less than or equal to the fidelity threshold value;

[0111] Step 706, taking the obtained logistics scheme of the picking service as a final logistics scheme of the picking service.

[0112] In step 701 of the above process, the planned warehouse logistics scheme includes a logistics workflow, and the logistics workflow includes a picking item unloading task workflow, a full-box changing workflow, and a full-box line throwing workflow. Specifically, after the simulation model system is provided, when the simulation model system is initialized, a simulation picker actively triggers to call logistics task information of a WMS, simulation destination locations of first picking item tasks are obtained, picking operations are performed, after the picking is completed, the logistics task information of the WMS is triggered again to obtain destination locations of next picking item tasks, picking operations are performed, and after the operations are completed, it is determined whether the picking items are full boxes. If the boxes are full, the logistics task information of the WMS is triggered to perform full-box operations, otherwise, the logistics task information of the WMS is continuously triggered to perform next picking item tasks. The above process is used to simulate the picking item tasks to obtain a simulation output result.

[0113] In step 702 of the above process, the simulation model system is provided according to the following process:

[0114] First step, adding an item shelf: setting a shelf height, a column width, and a number of layers and columns according to a warehouse logistics scheme layout, and a number of shelves;

[0115] Second step, adding a picking coordinate network according to the warehouse logistics scheme layout, and setting turning, straight line, direction, and other parameters;

[0116] Third step, setting a storage area and a segmented physical area;

[0117] Fourth step, adding each virtual entity, including receiving picking service information, sending a current location and item container information, and receiving various information to be executed when a picking service information is received again, a picking is completed, and a full-box instruction event;

[0118] Fifth step, setting running parameters of each virtual entity in the simulation model system, including picking loading time, maximum walking speed, acceleration, deceleration, or / and unloading time parameters;

[0119] Sixth step, adding an interface for modifying the picking simulation model;

[0120] The seventh step is to add a simulation output display interface to facilitate observation of the simulation model system's operation and task completion status.

[0121] In the sixth step, adding interfaces to modify the picking model can include: parameterizing the number of picking personnel, walking speed, and shelf attributes; adding simulation model operation control buttons, including an apply button and start, pause, and stop buttons; and providing feedback to the simulation model system through button responses. When a parameter is modified, clicking the apply button will update the simulation model system parameters.

[0122] In the seventh step, the simulation output results include one or more of the following: whether the initial work location is consistent with the actual location; whether the picking trajectory is consistent with the actual location; whether the reassigned work location is consistent with the actual location when the picking personnel change; and whether the work efficiency is consistent with the actual efficiency, etc.

[0123] Step 705 of the above process specifically includes: whether the planning system parameters involved in the simulation in the provided simulation model system are set correctly, whether the item order completion status and the picking business processing capacity meet expectations. If not, the planning system parameters involved in the simulation are checked in reverse, the provided simulation model system is rerun, the above process is repeated, and the simulation output results and actual output results are analyzed. Through such repeated iterations, a logistics solution for the picking business that meets expectations is finally obtained.

[0124] according to Figure 7 The execution of the aforementioned process yielded... Figure 8 The diagram shows the simulation output of the logistics plan for the picking operation, illustrating the relationship between the current warehouse inventory capacity and the time required to implement the logistics plan. In optional embodiments, the simulation output can also be displayed in graphical form, such as a line graph or bar chart.

[0125] As a specific example, the execution time of a picking operation can include, for example, Figure 8The simulation model system for planning the warehouse logistics scheme is shown in the figure. Wherein PersonNum is the number of current picking personnel, status identifies the task status, 1 represents the picking task is not pulled down, 2 represents the current picking task, 3 represents the completed picking task, and PersonDis is the walking distance of picking. For the task not pulled down, Queue1 represents the number of orders that have entered the order pool but have not been pulled down; for the current picking task, Queue2 represents the number of orders that have been pulled down from the order pool; for the completed picking task, Queue3 represents the number of orders that have been pulled down from the order pool and have completed the picking action. Here, since the input of the next picking task is based on the completion of the previous picking task for the entire warehouse picking task, the walking distance of the added picking task and the number of current picking personnel in the simulation model system are based on this to obtain a more comprehensive analysis result, so as to determine the optimization direction of the warehouse logistics scheme.

[0126] It can be seen that the reasons affecting the picking efficiency of the picking business of the warehouse logistics scheme are the number of single picking items and the walking distance of the picking personnel, which are related to the structure of the item order and the pull-down algorithm used by the WMS. Among them, the structure of the item order belongs to the problem to be solved in the planning level, the pull-down algorithm is to adopt what way to disassemble and integrate the item order and issue the corresponding picking task information; the walking distance can be set through the simulation involved planning system parameters in the simulation model system.

[0127] In the embodiment of the present application, the simulation model system for planning the warehouse logistics scheme includes the simulation involved planning system parameters, which can be directly set through the provided setting interface, such as Figure 9 As shown in the figure, Figure 9 The setting interface of the simulation involved planning system parameters in the simulation model system provided by the embodiment of the present application is shown in the figure.
