Technical Field

The present application relates to the technical field of warehouse management, and in particular to a tallying method, device, electronic equipment, storage medium and warehouse management system.

Background Art

Tallying is a common operation in warehouses. By centralizing the goods stored in multiple containers into one or more containers, more available containers are released, the storage capacity utilization of the entire warehouse is increased, and the efficiency of warehousing is improved. In addition, the goods are concentrated in fewer containers, which can increase the hit rate of goods arriving at a single container during outbound delivery, thereby improving outbound delivery efficiency.

In the prior art, when performing a tallying operation, it is necessary to perform a tallying operation on all containers in the warehouse within a fixed time period. Therefore, completing a tallying operation consumes a large amount of resources and is not flexible enough.

There is currently no effective technical solution to the above problems.

The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but only represents the selected embodiments of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in an accompanying drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

Please refer to Figure 1, which is a flow chart of a tally method in some embodiments of the present application. The tally method includes the following steps:

S101. Select n target tally containers whose current inventory quantities meet a first preset condition from a plurality of containers storing target commodities, where n is a positive integer greater than 1.

S102: Divide the n target tally containers into at least one target container combination, wherein each target container combination includes a plurality of target tally containers.

S103: Allocate the target commodities in each target container combination to m target tally containers in the target container combination, where m is a positive integer less than or equal to the number of target tally containers included in the target container combination.

For example, in step S101, the target product may be a product with high popularity and large shipment volume. Although tallying can improve overall operation efficiency, it consumes resources, thus affecting the efficiency of the main business, especially in a dense storage environment, where the time it takes to move a container in and out of a storage area is often longer than that of an ordinary storage area. Therefore, it is necessary to define a reasonable tallying range to achieve the best cost-effectiveness.

In this embodiment, the commodities with relatively large shipment volume can be sorted. Therefore, in some embodiments, before executing step S101, it is necessary to execute the step of selecting the target commodities: obtain the cumulative shipment quantity of each category of commodities within a preset time period. According to the cumulative shipment quantity of each category of commodities, the commodities with a shipment quantity greater than the first preset value are selected as the target commodities to be sorted. For example, the historical shipment data within the last 7 days can be selected according to the length of the order cycle (for example, 7 days). Then, the cumulative shipment quantity of each category of commodities is calculated and sorted; finally, according to the commonly used ABC classification method, find out the Class A commodities, and use the Class A commodities with larger shipment volume as the target commodities that need to be sorted.

Among them, when executing step S101, some containers with smaller current inventory can be selected as target tally containers. Of course, all containers that have not reached full capacity can also be selected as target tally containers. Among them, the current inventory is the inventory of the corresponding container before the tally operation. Of course, if all unfull containers are selected as target tally containers, the workload will increase and the tally efficiency will be reduced to a certain extent. Full capacity inventory refers to the maximum inventory of the container, and full capacity means that the current inventory of the container has reached the maximum inventory.

In some embodiments, when step S101 is specifically executed: the container whose current inventory is less than the tally threshold among the multiple containers storing the target commodity is used as the target tally container. Before step S101 is executed, the following steps need to be executed: S1011, obtaining the number of the target commodity picked each time in multiple picking tasks within a preset time period; S1012, obtaining the tally threshold of the target commodity according to the number of each target commodity picked each time. By selecting a reasonable tally threshold, the rationality of the selection of the tally container can be improved, and the cost-effectiveness of the tally operation can be improved.

In step S1011, each time the container is hit by the system for station picking, the picking operations of different storage area stations are calculated separately and regarded as different container station picking tasks. For example, container 1 receives 3 outbound tasks. After the system decides, container 1 needs to go to station a and station b for picking respectively. In this case, container 1 is considered to have completed 2 station pickings for this outbound delivery.

In step S1012, the number value with the most occurrences can be used according to the number values of each target commodity picked each time; if the number value with the most occurrences is one, the number value with the most occurrences is used as the tally threshold of the target commodity; if the number value with the most occurrences is multiple, the minimum number value among the multiple number values with the most occurrences is used as the tally threshold of the target commodity. Using the number with the most occurrences as the tally threshold of the target commodity can balance the number of tally containers and the range of tally containers, and reduce the range of tally while ensuring that the tally operation meets the needs of more picking operations as much as possible, which can improve the tally efficiency and save the tally time.

For example, the picking quantity of target commodity A in 7 consecutive days from Monday to Sunday is 3 units, 3 units, 4 units, 5 units, 3 units, 6 units, and 5 units. Therefore, it can be concluded that the maximum number of statistical occurrences is 3 units, so 3 units is set as the tally threshold of target commodity A.

For example, the picking quantity of target commodity A in the 7 consecutive days from Monday to Sunday is 3 units, 3 units, 5 units, 5 units, 3 units, 6 units, and 5 units. Therefore, it can be concluded that the most frequent statistical occurrences are 3 units and 5 units, which appear 3 times respectively. Since 3 units are less than 5 units, 3 units are set as the tally threshold of target commodity B.

Of course, it is not limited to this, and the quantity value closest to the mean among the quantity values with the largest number of statistical occurrences may also be used as the tally threshold.

In step S102, different storage area layouts or different numbers of target tally containers will result in different container movement times when the target tally container is transported. The number of container movements includes the number of movement times of the target tally container and the number of movement times of the obstacle container that blocks the target tally container. The number of movement times of the target tally container refers to the number of movement times of moving the target tally container from the storage area to the tally workstation; moving one target tally container to the tally workstation is counted as one movement of the target tally container.

Specifically, when executed, step S102 includes: calculating the number of container movements required to move all target tally containers in each of the selected container combinations to the tally workstation according to the container layout information of each target tally container in the corresponding storage area, wherein the container layout information is used to describe the arrangement of the containers in the corresponding storage area. The second preset condition is that the number of container movements is the smallest among all possible solutions.

In some embodiments, step S102 specifically includes the following sub-steps:

S1021, dividing the n target tally containers into a plurality of different container combination sets to be selected according to the current inventory and full inventory of each target tally container, wherein each of the container combination sets to be selected includes at least one container combination to be selected, each of the container combination to be selected includes a plurality of target tally containers, and each of the container combination sets to be selected includes the n target tally containers;

S1022, calculating the number of container movements required to move all target tally containers in each of the candidate container combinations to the tally workstation according to the container layout information of each target tally container in the corresponding storage area, wherein the container layout information is used to describe the arrangement of the containers in the corresponding storage area;

S1023: Filter out a set of to-be-selected container combinations whose movement times meet a second preset condition from the multiple to-be-selected container combinations as a target container combination set, and use each to-be-selected container combination in the target container combination set as a target container combination.

In step S1021, the set of container combinations to be selected and the combination of containers to be selected are illustrated. For example, the rated inventory of each target tally container is 10 units of target goods. There are 8 target tally containers in total, and the current inventory of the 8 target tally containers is 2 units, 2 units, 2 units, 2 units, 2 units, 3 units, 3 units, and 3 units, respectively. Among them, the candidate container combination sets that can be generated include but are not limited to: candidate container combination set x1{candidate container combination A(2, 2, 2, 2, 2), candidate container combination B(3, 3, 3)}, candidate container combination set x2{candidate container combination A(2, 2, 2, 2, 2), candidate container combination B(3, 3, 3)}, wherein, since different target tally containers with the same current inventory are regarded as different individuals for combination calculation, the candidate container combination set x2{candidate container combination A(2, 2, 2, 2, 2), candidate container combination B(3, 3, 3)} corresponds to 13 candidate container combination sets.

In step S1022, the number of times the container is moved includes the number of times the target tally container is moved and the number of times the obstacle container that blocks the target tally container is moved. The number of times the target tally container is moved refers to the number of times the target tally container is moved from the storage area to the tally workstation, wherein moving one target tally container to the tally workstation is counted as one movement of the target tally container.

As shown in FIG. 2 , FIG. 2 is a container layout diagram in storage area 1. Among them, multiple containers are arranged between the walls 10 of storage area 1. Among them, container 31 and container 32 are target tally containers. Container 40 is an obstacle container that prevents container 31 from being moved out. Area 20 is an empty area. As shown in FIG. 3 , FIG. 3 is a container layout diagram of storage area 2. Among them, container 33 and container 34 are target tally containers, and area 20 is an empty area. The number of moves is explained with FIG. 2 . For example, moving container 32 to the tally workstation is counted as one move. To move container 31 to the tally workstation, container 40 needs to be moved to other positions first, such as to the initial position of container 32, and then container 31 needs to be moved to the tally workstation. Therefore, for the part in storage area 1, the container needs to be moved three times. The number of moves is explained with FIG. 3 . For example, container 33 and container 34 can be directly moved to the tally workstation in sequence without moving other containers. Therefore, the number of container moves in storage area 2 is 2 times.

Among them, in step S1023, the second preset condition is that the number of movements required for the container is the minimum. Of course, it can also be that the number of movements meets the preset value.

Specifically, in some embodiments, the step S1021 may include: S10211, generating multiple initial container combination sets according to the current inventory and rated inventory of each target tally container, wherein each initial container combination set includes at least two container combinations to be selected, each container combination to be selected includes n target tally containers, and each container combination set to be selected includes the multiple target tally containers without duplication; S10212, selecting container combination sets whose full stock quantity and/or empty quantity meet the third preset condition from the multiple container combination sets as the container combination set to be selected, wherein the full stock quantity is the number of target tally containers whose current inventory reaches the rated inventory after tallying is completed, and the empty quantity is the number of target tally containers that are empty after tallying is completed. The third preset condition is the maximum full stock quantity and/or the maximum empty quantity, or the third preset condition may also be to first meet the maximum full stock quantity and then meet the maximum empty quantity; thereby improving the cost performance and tallying efficiency of tallying operation.

Among them, in step S10211, for example, the rated inventory of each target tally container is 10 units of target goods. There are 8 target tally containers in total, and the current inventory of the 8 target tally containers is 2 units, 2 units, 2 units, 2 units, 2 units, 3 units, 3 units, and 3 units, respectively. Computers are used for continuous exhaustive enumeration to eventually obtain various initial container combination sets, initial container combination set x1{candidate container combination A (2, 2, 2, 2, 2), candidate container combination B (3, 3, 3)}, initial container combination set x2{candidate container combination A (2, 2, 2, 2, 2), candidate container combination B (3, 3, 3)}, initial container combination set x3{candidate container combination A (2, 2, 2), candidate container combination B (2, 3, 3), candidate container combination C (2, 3, 3)}. After screening, to maximize the number of full containers, select the initial container combination set x1 {candidate container combination A (2, 2, 2, 2, 2), candidate container combination B (3, 3, 3)}, and the initial container combination set x2 {candidate container combination A (2, 2, 2, 2, 2) as the candidate container combination set. Of course, the candidate container combination set with the largest number of empty containers can be screened out in the same way.

Among them, in this step S103, in actual operation, the tallying operation is performed at the tallying workstation, and its goal is to distribute the commodities in more target tallying containers in a target container combination to fewer target tallying containers, so that some target tallying containers are empty and some target tallying containers are full. In the specific implementation process, this step S103 can be: distribute the target commodities in at least one target tallying container with a smaller current inventory in each of the target container combinations to m target tallying containers with larger current inventory.

Specifically, in some embodiments, step S103 includes the following sub-steps:

S1031. For each target container combination, the target commodities in the target tally container with the smallest current inventory in the target container combination are allocated to other target tally containers that are not full in the target container combination according to a preset priority order; wherein the preset priority order is the order from large to small according to the current inventory, and during allocation, the target commodities in the target tally container with the smallest current inventory are preferentially allocated to the target tally container with a larger current inventory until the target tally container with a larger current inventory is full;

S1032, determining whether the target tally container with the smallest current inventory in the target container combination is empty after the allocation operation is completed;

S1033: If it is not empty, then the tallying of the corresponding target container combination is terminated. S1034: If it is empty, then the empty target tallying container is deleted from the target container combination, and the process returns to execute the distribution of the target commodities in the target tallying container with the smallest current inventory in the target container combination to other target tallying containers in the target container combination according to the preset priority order.

Among them, in step S1031, for example, the current inventory of the target tally containers Y1, Y2, Y3, Y4 and Y5 in the target container combination Y is respectively: 2, 4, 6, 7, 8, 9. The full inventory of the target tally container is 10. Since the current inventory of Y5 is 9 units, only one more unit can be loaded. Therefore, firstly, 1 unit of the commodity of the target tally container Y1 is allocated to the target tally container Y5. Then, the remaining 1 unit of the target commodity of the target tally container Y1 is allocated to the target tally container Y4. In step S1032, since the 2 units of the target commodity of the target tally container Y1 are both allocated and become vacant. Therefore, the execution step is turned to delete the target tally container Y1 from the container combination Y. At this time, the target tally containers Y2, Y3, Y4 and Y5 are left, and the current inventory is respectively: 4, 6, 7, 9, 10. Go to step S1031. Since the target tally containers Y2, Y3, Y4 and Y5 have current stock volumes of 4, 6, 7, 9 and 10 respectively, the target tally container Y2 is the container with the smallest remaining current stock volume. Since the target tally container Y5 is full, the target tally container Y4 can still store one unit of target commodity. Therefore, firstly, one target commodity in the target tally container Y2 is allocated to the target tally container Y4, so that the target tally container Y4 is full. Then, the target tally container Y2 has 3 units of target commodities left. Since the target tally containers Y4 and Y5 are full, the target tally container Y3 is the target container with the largest current stock volume among the remaining unfull containers, and can still store 3 units of target commodities. Therefore, the 3 units of target commodities in the target tally container Y2 are allocated to the target tally container Y3, so that the target tally container Y3 is full, and the target tally container Y2 is empty. Therefore, the tally operation of the target container combination Y is completed.

The embodiment of the present application adopts setting the priority of allocating target commodities, and during allocation, the target commodities in the target tallying container with the smallest current inventory are preferentially allocated to the target tallying container with the largest current inventory until the target tallying container with the largest current inventory is full; thereby, the movement amount of the target commodities can be minimized, the tallying efficiency can be improved, and the tallying workload can be reduced.

It can be understood that, in some embodiments, step S103 includes the following sub-steps:

S1035. For each target container combination, the target commodities in the target tally container with the smallest current inventory in the target container combination are allocated to one or more other target tally containers in the target container combination until the target commodities in the target tally container with the smallest current inventory are allocated or all other target tally containers in the target container combination are full.

S1036: After the target commodities in the target tally container with the smallest current inventory are completely allocated, continue to allocate the target commodities in another target tally container with the smallest inventory in the target container combination to one or more other target tally containers in the target container combination that are not yet full.

In step S1035, for example, the current inventory of the target tally containers Y1, Y2, Y3, Y4 and Y5 in the target container combination Y is respectively 2, 4, 6, 7, 8 and 9. The full inventory of the target tally container is 10 units of target commodities. Therefore, the two units of target commodities in the target tally container Y1 are allocated to one or more of the target tally containers Y2, Y3, Y4 and Y5.

In some embodiments, the target commodities in the target tally container with the smallest current inventory in the target container combination can be allocated to the target tally container with the largest current inventory in the target container combination; and when the target tally container with the largest current inventory is full and the target commodities in the target tally container with the smallest current inventory have not been allocated, the remaining target commodities in the target tally container with the smallest current inventory will continue to be allocated to another target tally container with the largest inventory in the target tally container that is not full in the target container combination. That is, one of the two unit target commodities in the target tally container Y1 is allocated to the target tally container Y5, and then the other unit target commodity in the two unit target commodities in the target tally container Y1 is allocated to the target tally container Y4.

Among them, in step S1036, after the commodities in the target tally container Y1 are allocated, the 4 units of target commodities in the target tally container Y2 are continuously allocated, and can be allocated to one or more of the unfilled target tally containers Y3 and Y4 in the target container combination Y. Of course, in some embodiments, the target commodities in the target tally container with the smallest current inventory in the target container combination can be allocated to a target tally container with the largest current inventory in the target container combination; and when the target tally container with the largest current inventory is full and the target commodities in the target tally container with the smallest current inventory have not been allocated, the remaining target commodities in the target tally container with the smallest current inventory continue to be allocated to another target tally container with the largest inventory in the unfilled target tally container in the target container combination. That is, firstly allocate one of the 4 units of target commodities in the target tally container Y2 to the target tally container Y4, so that the target tally container Y4 is full, and then allocate the remaining 3 units of target commodities in the target tally container Y2 to the target tally container Y3, so that the target tally container Y3 is full. Finally, since the target tally containers Y3, Y4 and Y5 are all full and the target tally containers Y1 and Y2 are empty, the tally operation on the target tally container combination is completed.

As can be seen from the above, the embodiment of the present application selects n target tally containers whose current inventory volume meets the first preset condition from multiple containers storing target commodities, where n is a positive integer greater than 1; divides the n target tally containers into at least one target container combination, wherein each target container combination includes multiple target tally containers; allocates the target commodities in each target container combination to m target tally containers in the target container combination, wherein m is a positive integer less than or equal to the number of target tally containers included in the target container combination; due to the use of n target tally containers whose current inventory volume meets the first preset condition, the tallying operation is more targeted, which can improve the tallying efficiency and reduce the tallying cost.

Please refer to Figure 4, which is a flow chart of a tally method in some embodiments of the present application. The tally method also includes the following steps:

S201. Obtain container layout information in a storage area where each target tally container is located, where the container layout information is used to describe the arrangement of the containers in the storage area.

S202, dispatching robots in sequence according to the container layout information to transport the n target tally containers to the tally workstation for tallying, wherein when transporting the target tally containers, the target tally containers that are not blocked by other containers are transported first.

In step S201, the storage area may be a warehouse or an area within a warehouse. As shown in FIG2 and FIG3, the container layout of storage area 1 and storage area 2 are shown.

In step S202, for example, if the target tally container blocked by other target tally containers or obstacle containers is moved first, it is easy to cause other unblocked target tally containers to be blocked by other containers after adjusting their positions in the process of resolving the obstacles to the target tally container. Therefore, by moving the target tally container that is not blocked by other containers first, the transportation efficiency can be improved and the number of container movements can be reduced.

It can be understood that in some embodiments, after executing step S103, the following steps are further included: generating one or more tally tasks, and sending the one or more tally tasks to corresponding tally workstations, wherein each tally task is used to instruct the tally workstation to tally the containers.

If a tallying task is generated, the tallying task may be sent to a tallying workstation. At this time, the at least one target container combination obtained by the division in S102 may be transported to the tallying workstation for tallying operation.

If multiple tally tasks are generated, these multiple tally tasks can be sent to a tally workstation respectively, so that the tally operation can be performed in parallel at multiple tally workstations, which can improve the speed of tallying. Each tally task can correspond to one or more target container combinations, and the sum of the number of target container combinations corresponding to the multiple tally tasks generated is equal to the number of target container combinations obtained by division in S102. Of course, these multiple tally tasks can also be sent to the same tally workstation; or, some of the tally tasks can be sent to the same tally workstation, and the other parts of the tally tasks can be sent to different tally workstations respectively, which is not limited in this application.

That is to say, in some embodiments, a tally task can be executed independently, or multiple tally tasks can be executed crosswise or in parallel. The tally task is generated by using the tally method in the above embodiment.

In some embodiments, as shown in FIG5 , the tally method, after executing step S103 or step S205, further includes the following steps:

S301, determining whether each target tally container is empty.

S302: If it is empty, return the empty target tally container to the corresponding storage area.

S303: If it is not empty, determine whether the current inventory of the target tally container has reached the full inventory.

S304: If the capacity is reached, the target tally container is returned to the corresponding storage area.

S305: If the capacity is not reached, determine whether the target tally container is associated with other tally tasks.

S306: If no other tallying tasks are associated, the target tallying container is returned to the corresponding storage area.

S307: If it is related to other tallying tasks, continue tallying processing on the target tallying container.

In step S302, the empty target tally container may be transported to a storage area corresponding to the empty containers, for example, a dedicated empty container warehouse.

In step S304, the target tally container that has reached full inventory may be transported back to the location where the container was placed in the storage area before it was moved to the automatic tally station, or a storage area may be replanned to place the target tally container.

Since a target tally container may be associated with several tally tasks at the same time, the target tally container can continue to be tallied when it is not full. The target tally container can be moved or transported according to the position of the tally workstation corresponding to the next tally task of the target tally container, so that the target tally container can quickly enter the next tally processing task.

Please refer to FIG6 , which is a schematic diagram of the structure of a tally device in some embodiments of the present application. The tally device includes: a selection module 401 , a division module 402 and a generation module 403 .

Among them, the selection module 401 is used to select n target tally containers whose current inventory meets the first preset condition from multiple containers storing target commodities, and n is a positive integer greater than 1. Among them, the target commodity is a commodity with high popularity and large shipment volume. Although tallying can improve the overall operation efficiency, the tallying operation will consume resources, thereby affecting the efficiency of the main business, especially in a dense storage environment, the time taken for the container to move in and out of the storage area is often longer than that of an ordinary storage area. Therefore, it is necessary to define a reasonable tally range to strive for the best cost performance. In this embodiment, tallying can be adopted for commodities with relatively large shipment volumes. Therefore, in some embodiments, the selection module 401 is also used to: obtain the cumulative outbound quantity of each category of commodities within a preset time period; select commodities with an outbound quantity greater than the first preset value as the target commodities to be tallied according to the cumulative outbound quantity of each category of commodities. For example, historical outbound data within the last 7 days can be selected according to the length of the order cycle (for example, 7 days). Then, calculate the cumulative shipment quantity of each type of goods and sort them; finally, find out Class A goods according to the commonly used ABC classification method, and take Class A goods with larger shipment volume as the target goods that need to be sorted.

Among them, the selection module 401 can select some containers with smaller current inventory as target tally containers, and of course, all containers with less than full inventory can also be used as target tally containers. Among them, the current inventory is the inventory of the corresponding container before the tally operation. Of course, if all unfull containers are selected as target tally containers, the workload will increase and the tally efficiency will be reduced to a certain extent.

In some embodiments, the selection module 401 is used to select a container whose current inventory is less than a tally threshold among multiple containers storing the target commodity as a target tally container. The selection module 401 is also used to obtain the number of the target commodity picked each time in multiple picking tasks within a preset time period; and obtain the tally threshold of the target commodity according to the number of each target commodity picked each time.

Wherein, the division module 402 is used to divide the n target tally containers into at least one target container combination, wherein each target container combination includes multiple target tally containers. Different storage area layouts or different numbers of target tally containers will result in different container movement times when the target tally containers are transported. Wherein, the number of container movements includes the number of movement times of the target tally container and the number of movement times of the obstacle container that blocks the target tally container. Wherein, the number of movement times of the target tally container refers to the number of movements of the target tally container from the storage area to the tally workstation; moving one target tally container to the tally workstation is counted as one movement of the target tally container.

The division module 402 includes: a division unit, configured to divide the n target tally containers into a plurality of different container combination sets to be selected according to the current inventory and full inventory of each target tally container, wherein each of the container combination sets to be selected includes at least one container combination to be selected, each of the container combination to be selected includes a plurality of target tally containers, and each of the container combination sets to be selected includes n target tally containers; a calculation unit, configured to calculate the number of container movements required to move all target tally containers in each of the container combination sets to the tally workstation according to the container layout information of each of the target tally containers in the corresponding storage area, wherein the container layout information is used to describe the arrangement of the containers in the corresponding storage area; and a selection unit, configured to select a container combination set to be selected whose number of movements meets a second preset condition from the plurality of container combination sets to be selected as a target container combination set, and select each container combination to be selected in the target container combination set as a target container combination.

Among them, examples are given for the combination set of containers to be selected and the combination of containers to be selected. For example, the rated inventory of each target tally container is 10 units of target goods. There are 8 target tally containers in total, and the current inventory of the 8 target tally containers is 2 units, 2 units, 2 units, 2 units, 2 units, 3 units, 3 units, and 3 units respectively. Among them, the combination set of containers to be selected that can be generated includes but is not limited to: the combination set of containers to be selected x1{combination of containers to be selected A (2, 2, 2, 2, 2), combination of containers to be selected B (3, 3, 3)}, the combination set of containers to be selected x2{combination of containers to be selected A (2, 2, 2, 2, 2), combination of containers to be selected B (3, 3, 3)}, among which, since different target tally containers with the same current inventory are regarded as different individuals for combined calculation, the combination set of containers to be selected x2{combination of containers to be selected A (2, 2, 2, 2, 2), combination of containers to be selected B (3, 3, 3)} corresponds to 13 combinations of containers to be selected.

The number of times the container is moved includes the number of times the target tally container is moved and the number of times the obstacle container that blocks the target tally container is moved. The number of times the target tally container is moved refers to the number of times the target tally container is moved from the storage area to the tally workstation, wherein moving one target tally container to the tally workstation is counted as one movement of the target tally container. The second preset condition is that the number of moves required for the container is the minimum. Of course, it can also be that the number of moves meets the preset value.

Specifically, in some embodiments, the division unit is specifically used to: generate multiple initial container combination sets according to the current inventory and rated inventory of each target tally container, wherein each initial container combination set includes at least two container combinations to be selected, each container combination to be selected includes n target tally containers, and each container combination set to be selected includes the multiple target tally containers without duplication; filter out container combination sets whose full stock quantity and/or empty quantity meet the third preset condition from the multiple container combination sets as the container combination set to be selected, wherein the full stock quantity is the number of target tally containers whose current inventory reaches the rated inventory after tallying is completed, and the empty quantity is the number of target tally containers that are empty after tallying is completed. The third preset condition is the maximum full stock quantity and/or the maximum empty quantity, or the third preset condition can also be to first meet the maximum full stock quantity and then meet the maximum empty quantity.

For example, the rated inventory of each target tally container is 10 units of target goods. There are 8 target tally containers in total, and the current inventory of the 8 target tally containers is 2 units, 2 units, 2 units, 2 units, 2 units, 3 units, 3 units, and 3 units, respectively. By using a computer to perform continuous exhaustive enumeration, various initial container combination sets are finally obtained, including the initial container combination set x1{candidate container combination A(2, 2, 2, 2, 2), candidate container combination B(3, 3, 3)}, the initial container combination set x2{candidate container combination A(2, 2, 2, 2, 2), candidate container combination B(3, 3, 3)}, and the initial container combination set x3{candidate container combination A(2, 2, 2), candidate container combination B(2, 3, 3), candidate container combination C(2, 3, 3)}. After screening, to maximize the number of full containers, select the initial container combination set x1 {candidate container combination A (2, 2, 2, 2, 2), candidate container combination B (3, 3, 3)}, and the initial container combination set x2 {candidate container combination A (2, 2, 2, 2, 2) as the candidate container combination set. Of course, the candidate container combination set with the largest number of empty containers can be screened out in the same way.

Among them, the generation module 403 is used to allocate the target commodities in each target container combination to the m target tally containers in the target container combination to generate a tally plan, wherein m is a positive integer less than or equal to the number of target tally containers included in the target container combination. The tallying operation is performed at the tally workstation, and its goal is to allocate the commodities in more target tally containers in a target container combination to fewer target tally containers, so that some target tally containers are empty and some target tally containers are full. In the specific execution process, the generation module 403 is used to: allocate the target commodities in at least one target tally container with a smaller current inventory in each of the target container combinations to the m target tally containers with a larger current inventory.

In some embodiments, the generation module 403 includes: an allocation unit, a first judgment unit, an end unit, and a loop unit. The allocation unit is used to allocate the target goods in the target tally container with the smallest current inventory in the target container combination to other unfilled target tally containers in the target container combination according to a preset priority order for each target container combination; wherein the preset priority order is in order from large to small according to the current inventory, and when allocating, the target goods in the target tally container with the smallest current inventory are preferentially allocated to the target tally container with a larger current inventory until the target tally container with a larger current inventory is full. The first judgment unit is used to determine whether the target tally container with the smallest current inventory in the target container combination is empty after the allocation operation is completed. The end unit is used to end the tallying of the corresponding target container combination if it is not empty. The circulation unit is used to delete the empty target tally container from the target container combination if it is empty, and return it to the allocation unit, so that the allocation unit executes the allocation of the target commodities in the target tally container with the smallest current inventory in the target container combination to other target tally containers in the target container combination according to a preset priority order.

It can be understood that in some embodiments, the generation module 403 is specifically used to: for each target container combination, allocate the target commodities in the target tallying container with the smallest current inventory in the target container combination to one or more other target tallying containers in the target container combination until the target commodities in the target tallying container with the smallest current inventory are allocated or all other target tallying containers in the target container combination are full; and to continue to allocate the target commodities in another target tallying container with the smallest inventory in the target container combination to one or more other target tallying containers that are not yet full in the target container combination after the target commodities in the target tallying container with the smallest current inventory are allocated.
