Detailed Description

The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, fig. 1 is a flowchart of a cargo handling method according to some embodiments of the application. The tallying method comprises the following steps:

s101, selecting n target tally containers with the current inventory meeting a first preset condition from a plurality of containers for storing target commodities, wherein n is a positive integer greater than 1.

S102, dividing the n target tally containers into at least one target container combination, wherein each target container combination comprises a plurality of target tally containers.

S103, distributing 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 the target tally containers in the target container combination.

For example, in the step S101, the target commodity may be a commodity having a high heat and a large shipment amount. Although the overall operation efficiency can be improved by the tallying, the tallying operation consumes resources, so that the efficiency of backbone business is affected, and especially in a dense storage environment, the time taken by the container to move in and out of the storage area once is often longer than that of a common storage area. Therefore, a reasonable cargo management range needs to be defined, and the best cost performance is strived for.

In this embodiment, goods having a relatively large shipment may be sorted. Therefore, in some embodiments, before performing this step S101, a step of selecting the target commodity needs to be performed: and acquiring the accumulated warehouse-out quantity of each type of commodity in a preset time period. And selecting commodities with the ex-warehouse quantity larger than a first preset value as target commodities to be tidied according to the accumulated ex-warehouse quantity of each class of commodities. For example, historical shipment data over the last 7 days may be selected based on the length of the order cycle (e.g., 7 days). Then, calculating the accumulated warehouse-out quantity of various commodities, and sorting; and finally, finding out the class A commodity according to the common ABC classification method, and taking the commodity with larger delivery quantity, namely the class A commodity, as a target commodity needing to be managed.

In the step S101, some containers with smaller current inventory may be selected as target shipping containers, and of course, all containers with less than full inventory may be selected as target shipping containers. Wherein the current inventory is the inventory of the corresponding container prior to the tally operation. Of course, if all the containers that are not full are selected as the target shipping containers, the workload is increased, and the shipping efficiency is somewhat reduced. Full inventory refers to the maximum inventory of containers, while full refers to the current inventory of containers having reached the maximum inventory.

In some embodiments, this step S101 is specifically performed as: and taking the container with the current inventory quantity smaller than the tally threshold value in the plurality of containers for storing the target commodity as a target tally container. Before this step S101 is performed, the following steps are required: s1011, acquiring the number value of each selected time in multiple selecting tasks of the target commodity in a preset time period; s1012, acquiring a tally threshold of each target commodity according to the number value of each selected target commodity. By selecting a reasonable tally threshold, the rationality of the selection of the tally container can be improved, and the cost performance of the tally operation can be improved.

In this step S1011, where the container is picked up to station each time it is hit by the system, the picking operations for the different storage area sites are calculated separately and considered as different container-to-station picking assignments. For example, container 1 receives 3 shipment tasks, and after a system decision, container 1 needs to be picked up by sequentially going to station a and station b respectively, then container 1 is considered to have completed 2 picks up to station this time.

In this step S1012, a count value that counts the number of occurrences to the maximum according to the count value of each of the target items to be picked at each time may be adopted; if the number value with the largest number of the counted occurrences is one, the number value with the largest number of the counted occurrences is used as a tally threshold of the target commodity; and if the number value with the most counted occurrence number is a plurality of, taking the minimum number value in the number values with the most counted occurrence number as the tally threshold of the target commodity. The number of the tally containers and the range of the tally containers can be weighed by taking the most numerical value of the counted occurrence times as the tally threshold of the target commodity, the tally range is reduced on the premise that the tally operation meets the requirements of more picking operations as much as possible, the tally efficiency can be improved from the container, and the tally time is saved.

For example, the picking number of the target commodity a in 7 days consecutive from monday to sunday is 3 units, 4 units, 5 units, 3 units, 6 units, 5 units in this order. Therefore, it can be derived that the number of statistical occurrences is at most 3 units, and therefore, 3 units are set as the tally threshold of the target commodity a.

For example, the picking number of the target commodity a in 7 days consecutive from monday to sunday is 3 units, 5 units, 3 units, 6 units, 5 units in this order. Thus, it can be derived that the number of statistical occurrences is at most 3 units and 5 units, which occur 3 times respectively. Since 3 units are smaller than 5 units, 3 units are set as the tally threshold of the target commodity B.

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

In this step S102, the layout of different storage areas or the number of different target shipping containers is different, which results in different numbers of movements of the containers when the target shipping containers are transported. The number of movements of the container includes the number of movements of the target container and the number of movements of the barrier container that blocks the target container. The moving times of the target tally container refer to the moving times of the target tally container from the storage area to the tally workstation; and moving one target tally container to a tally workstation to calculate that the target tally container is moved once.

In the specific implementation, the step S102 includes: and calculating the number of times of moving the containers required for moving all the target tally containers in each container combination set to be selected 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 for describing the arrangement condition of the containers in the corresponding storage area. Wherein the second preset condition is that the number of movements of the container is minimal among all possible solutions.

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

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

S1022, calculating the moving times of the containers required to move all the target tally containers in each container combination set to be selected to a 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 for describing the arrangement condition of the containers in the corresponding storage area;

s1023, screening the container combination set to be selected, the number of which is met with a second preset condition, from the container combination sets to be selected, as a target container combination set, and taking each container combination to be selected in the target container combination set as a target container combination.

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

In step S1022, the number of movements of the container includes the number of movements of the target container and the number of movements of the barrier container that blocks the target container. The moving times of the target tally containers refer to the moving times of the target tally containers from the storage area to the tally workstation, wherein one target tally container is moved to the tally workstation to calculate the target tally container to be moved once.

As shown in fig. 2, fig. 2 is a layout view of the container in the storage area 1. Wherein a plurality of containers are arranged between the walls 10 of the storage area 1. The container 31 and the container 32 are target cargo containers. The container 40 is a barrier container that impedes removal of the container 31. The region 20 is an empty region. As shown in fig. 3, fig. 3 is a container layout diagram of the storage area 2. Wherein, container 33 and container 34 are target cargo containers, and region 20 is an empty region. The number of movements will be described with reference to fig. 2, for example, the container 32 is moved to the storage area 1 once, and the container 31 needs to be moved to the storage area 1 three times since the container 40 needs to be moved to another position, for example, to the initial position of the container 32 and then the container 31 needs to be moved to the storage area 1. The number of movements will be described with reference to fig. 3, for example, the containers 33 and 34 may be moved directly to the sorting station in order without moving other containers, and thus the number of movements for the containers in the storage area 2 is 2.

In step S1023, the second preset condition is that the number of movements required for the container is minimum. Of course, the number of movements may be set to satisfy a predetermined value.

Specifically, in some embodiments, the step S1021 may include: s10211, generating a plurality of initial container combination sets according to the current inventory and the rated inventory of each target tally container, wherein each initial container combination set comprises at least two container combinations to be selected, each container combination to be selected comprises n target tally containers, and each container combination set to be selected comprises the plurality of target tally containers and is not repeated; s10212, screening out a container combination set with the full storage quantity and/or the empty quantity meeting a third preset condition from the container combination sets as a container combination set to be selected, wherein the full storage quantity is the quantity of target tally containers with the current inventory reaching the rated inventory after finishing the tally, and the empty quantity is the quantity of the empty target tally containers after finishing the tally. The third preset condition is that the sum of the full storage quantity is maximum and/or the empty quantity is maximum, or the third preset condition can also be that the full storage quantity is maximum preferentially and then the empty quantity is maximum; therefore, the cost performance and the tallying efficiency of the tallying operation can be improved.

In step S10211, for example, the rated inventory of each target shipping container is 10 units of target commodity. The total target tally containers are 8, and the current inventory of the 8 target tally containers is respectively 2 units, 3 units and 3 units in sequence. The computer is adopted for continuous exhaustion, and various initial container combination sets are finally obtained, initial container combination set x1{ candidate container combination A (2, 2), candidate container combination B (3) 3, 3) } an initial container combination set x2{ alternate container combination A (2, 2) }, the container combination to be selected B (3, 3) }, the initial container combination set x2{ the container combination to be selected a (2, 2), the container combination to be selected B (2, 3), the container combination to be selected C (2, 3) }. Screening to maximize the number of full memory, then the initial container combination set x1{ the candidate container combination a (2, 2), the candidate container combination B (3, 3] 3) the initial container combination set x2{ the candidate container combination a (2, 2) as the candidate container combination set. Of course, the same thing can screen out the container combination set to be selected with the largest empty number.

In the step S103, in the actual operation, the operations of the tallying are performed at the tallying workstation, and the goal is to distribute the articles in the more target tallying containers in one target container combination to the fewer target tallying containers, so that some target tallying containers are empty and some target tallying containers are full. In a specific implementation process, the step S103 may be: and distributing the target goods in at least one target tally container with smaller current inventory in each target container combination into m target tally containers with larger current inventory.

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

S1031, for each target container combination, distributing target commodities in a target tally container with the smallest current inventory in the target container combination to other target tally containers with less than full capacities in the target container combination according to a preset priority order; the preset priority order is the order from big to small according to the current inventory, and when the target inventory is distributed, the target commodities in the target tally container with the smallest current inventory are preferentially distributed to the target tally container with the larger current inventory until the target tally container with the larger current inventory is full;

S1032, judging whether the target tally container with the smallest current inventory in the target container combination is empty after the distribution operation is finished;

and S1033, if the container is not empty, finishing the tally corresponding to the target container combination. S1034, if the target container is empty, deleting the empty target container from the target container combination, and returning to execute the allocation of the target commodity in the target container with the smallest current inventory in the target container combination to other target container in the target container combination according to the preset priority order.

In step S1031, for example, the current inventory amounts of the target shipping containers Y1, Y2, Y3, Y4, and Y5 in the target container group Y are respectively: 2. 4,6, 7, 8, 9. And the full inventory of the target shipping container is 10. Since the current inventory of Y5 is 9 units and only one unit can be reloaded, 1 unit of goods of the target shipping container Y1 is first allocated to the target shipping container Y5. Then, the remaining 1 unit target commodity of the target shipping container Y1 is assigned to the target shipping container Y4. In step S1032, the target commodity of 2 units of the target shipping container Y1 is dispensed to be in a blank state. Therefore, the execution step is shifted to delete the target container Y1 from the container set Y, and at this time, the target containers Y2, Y3, Y4 and Y5 are left, and the current stock amounts are respectively as follows in sequence: 4. 6, 7, 9, 10. Turning to step S1031, since the target cargo tanks Y2, Y3, Y4 and Y5 are respectively: 4. 6, 7, 9, 10. Therefore, the target shipping container Y2 is the container with the smallest current inventory remaining, and the target shipping container Y4 can store one unit of target commodity since the target shipping container Y5 is full. Therefore, one target commodity in the target tally container Y2 is first allocated to the target tally container Y4, so that the target tally container Y4 is full. Then, 3 units of target commodities are left in the target tally container Y2, and after the target tally containers Y4 and Y5 are full, the target tally container Y3 is the target commodity with the largest current inventory in the remaining target container with the insufficient inventory, and 3 units of target commodities can be stored, so that 3 units of target commodities in the target tally container Y2 are distributed to the target tally container Y3, the target tally container Y3 is full, and the target tally container Y2 is empty; thus, the tally operation for the target container combination Y ends.

It will be appreciated that in some embodiments, step S103 includes the sub-steps of:

s1035, for each target container combination, distributing the target goods in the target container with the smallest current inventory in the target container combination to one or more other target container in the target container combination until the target goods in the target container with the smallest current inventory are distributed or the other target container in the target container combination is full.

S1036, after the target goods in the target tally container with the minimum current inventory are distributed, continuing to distribute the target goods in another target tally container with the minimum inventory in the target container combination to one or more other target tally containers which are not fully contained in the target container combination.

In step S1035, for example, the current inventory amounts of the target shipping containers Y1, Y2, Y3, Y4, and Y5 in the target container group Y are respectively: 2.4, 6, 7, 8, 9. And the full capacity inventory of the target tally container is 10 units of target goods. Thus, two unit target products in the target shipping container Y1 are assigned to one or more of the target shipping containers Y2, Y3, Y4, and Y5.

In some embodiments, the target commodity in the target container with the smallest current inventory in the target container combination may be allocated to one target container with the largest current inventory in the target container combination; and under the condition that the target tally container with the largest current inventory has been fully loaded and the target commodity in the target tally container with the smallest current inventory is not already allocated, continuing to allocate the remaining target commodity in the target tally container with the smallest current inventory to another target tally container with the largest inventory in the target tally container which is not fully loaded in the target container combination. That is, one of the two unit target products in the target shipping container Y1 is assigned to the target shipping container Y5, and then the other of the two unit target products in the target shipping container Y1 is assigned to the target shipping container Y4.

In step S1036, after the goods in the target container Y1 are distributed, the distribution of the 4 units of the target goods in the target container Y2 is continued, and the goods may be distributed to one or more of the target containers Y3 and Y4 which are not fully contained in the target container group Y. Of course, in some embodiments, the target commodity in the target container with the smallest current inventory in the target container combination may be allocated to the target container with the largest current inventory in the target container combination; and under the condition that the target tally container with the largest current inventory has been fully loaded and the target commodity in the target tally container with the smallest current inventory is not already allocated, continuing to allocate the remaining target commodity in the target tally container with the smallest current inventory to another target tally container with the largest inventory in the target tally container which is not fully loaded in the target container combination. That is, one of the 4 units of target commodities in the target shipping container Y2 is allocated to the target shipping container Y4 first, so that the target shipping container Y4 is full, and then the remaining 3 units of target commodities in the target shipping container Y2 are allocated to the target shipping container Y3, so that the target shipping container Y3 is full. Finally, as the target tally containers Y3, Y4 and Y5 are full, the target tally containers Y1 and Y2 are empty, and the tally operation on the target tally container combination is completed.

As can be seen from the above, in the embodiment of the present application, n target shipping containers whose current inventory satisfies the first preset condition are selected from a plurality of containers storing target commodities, where n is a positive integer greater than 1; dividing the n target shipping containers into at least one target container combination, wherein each target container combination comprises a plurality of target shipping containers; distributing 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; because the n target tally containers meeting the first preset condition for the current inventory are adopted, the pertinence of the tally operation is stronger, the tally efficiency can be improved, and the tally cost can be reduced.

Referring to fig. 4, fig. 4 is a flowchart of a cargo handling method according to some embodiments of the application. The tallying method further comprises the following steps:

S201, acquiring container layout information in a storage area where each target tally container is located, wherein the container layout information is used for describing arrangement conditions of containers in the storage area.

S202, sequentially dispatching the robots to convey the n target tally containers to a tally workstation for tally according to the container layout information, wherein when the target tally containers are conveyed, the target tally containers which are not blocked by other containers are conveyed first.

In step S201, the storage area may be a warehouse or an area within a warehouse. As shown in fig. 2 and 3, the container layout of the storage area 1 and the storage area 2 is shown.

In step S202, for example, if the target container blocked by another target container or the obstacle container is carried first, it is easy to cause blocking of another container after another unblocked target container becomes the adjusted position in the process of solving the obstacle to the target container. Therefore, by first transporting the target shipping container that is not blocked by another container, the transport efficiency can be improved and the number of movements of the container can be reduced.

It will be appreciated that in some embodiments, after step S103 is performed, the following steps are further included: and generating one or more tally tasks, and issuing the one or more tally tasks to corresponding tally workstations, wherein each tally task is used for indicating the tally workstation to tally the container.

If a tally task is generated, the tally task may be issued to a tally workstation, and at this time, the at least one target container combination obtained by dividing in S102 may be transported to the tally workstation for a tally job.

If a plurality of tally tasks are generated, the plurality of tally tasks can be respectively issued to one tally workstation, so that the tally operation can be performed in parallel at the plurality of tally workstations, and the tally speed can be improved. Each of the tally tasks may correspond to 1 or more target container combinations, and the sum of the numbers of the target container combinations corresponding to the generated plurality of tally tasks is equal to the number of the target container combinations divided in S102. Of course, the plurality of tally tasks may be issued to the same tally workstation; or some of the tally tasks may be issued to the same tally workstation, and other parts of the tally tasks may be issued to different tally workstations, which is not limited in the present application.

That is, in some embodiments, one tally task may be performed separately, or multiple tally tasks may be performed in cross or parallel. The tally task is generated by adopting the tally method in the embodiment.

In some embodiments, as shown in fig. 5, the tally method further includes the following steps after performing step S103 or step S205:

s301, judging whether each target tally container is empty or not.

And S302, if the storage area is empty, returning the empty target tally container to the corresponding storage area.

S303, if the container is not empty, judging whether the current inventory of the target tally container reaches the full inventory.

And S304, if the storage area is full, returning the target tally container to the corresponding storage area.

S305, if the full capacity is not reached, judging whether the target tally container is related to other tally tasks.

And S306, if other tally tasks are not associated, returning the target tally container to the corresponding storage area.

S307, if the target tally container is related to other tally tasks, continuing to tally the target tally container.

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

In step S304, the target container with the full storage capacity may be transported back to the position where the container is placed in the storage area before the automatic container station is moved, or the position of one storage area may be rearranged to place the target container.

Wherein, because one target tally container may be associated with several tally tasks at the same time, the target tally container may be continuously tally processed under the condition that the target tally container is not full. The system can move or carry according to the position of a tally workstation corresponding to the next tally task of the target tally container, so that the system can quickly enter the next tally processing task.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a cargo handling device according to some embodiments of the application. The tally device includes: a selection module 401, a division module 402 and a generation module 403.

The selecting module 401 is configured to select n target shipping containers with current inventory meeting a first preset condition from a plurality of containers storing target commodities, where n is a positive integer greater than 1. Wherein the target commodity is a commodity with higher heat and larger delivery capacity. Although the overall operation efficiency can be improved by the tallying, the tallying operation consumes resources, so that the efficiency of backbone business is affected, and especially in a dense storage environment, the time taken by the container to move in and out of the storage area once is often longer than that of a common storage area. Therefore, a reasonable cargo management range needs to be defined, and the best cost performance is strived for. In this embodiment, goods having a relatively large shipment may be sorted. Thus, in some embodiments, the selection module 401 is further to: acquiring the accumulated warehouse-out quantity of each type of commodity in a preset time period; and selecting commodities with the ex-warehouse quantity larger than a first preset value as target commodities to be tidied according to the accumulated ex-warehouse quantity of each class of commodities. For example, historical shipment data over the last 7 days may be selected based on the length of the order cycle (e.g., 7 days). Then, calculating the accumulated warehouse-out quantity of various commodities, and sorting; and finally, finding out a class A commodity according to a common ABC classification method, and taking the commodity with larger commodity output of the class A as a target commodity needing to be managed.

The selection module 401 may select some containers with smaller current inventory as the target shipping containers, and of course, all containers with less than full inventory may be used as the target shipping containers. Wherein the current inventory is the inventory of the corresponding container prior to the tally operation. Of course, if all the containers that are not full are selected as the target shipping containers, the workload is increased, and the shipping efficiency is somewhat reduced.

In some embodiments, the selection module 401 is configured to take, as the target shipping container, a container of the plurality of containers storing the target merchandise having a current inventory level less than the shipping threshold. The selection module 401 is further configured to obtain a number value of each picked item in multiple picking tasks of the target commodity in a preset time period; and acquiring a tally threshold of each target commodity according to the number value of each selected target commodity.

The dividing module 402 is configured to divide the n target shipping containers into at least one target container combination, where each target container combination includes a plurality of target shipping containers. Different storage areas and different numbers of target shipping containers may result in different numbers of container movements during the handling of the target shipping containers. The number of movements of the container includes the number of movements of the target container and the number of movements of the barrier container that blocks the target container. The moving times of the target tally container refer to the moving times of the target tally container from the storage area to the tally workstation; and moving one target tally container to a tally workstation to calculate that the target tally container is moved once.

The partitioning module 402 includes: the dividing unit is used for dividing the n target tally containers into a plurality of different container combination sets according to the current inventory and the full inventory of each target tally container, wherein each container combination set comprises at least one container combination to be selected, each container combination to be selected comprises a plurality of target tally containers, and each container combination set to be selected comprises n target tally containers; the calculation unit is used for calculating the moving times of the containers required to move all the target tally containers in each container combination set to be selected 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 for describing the arrangement condition of the containers in the corresponding storage area; and the selection unit is used for screening the container combination set to be selected, the movement times of which meet the second preset condition, from the container combination set to be selected as a target container combination set, and taking each container combination to be selected in the target container combination set as a target container combination.

Wherein the set of combinations of containers to be selected and the combination of containers to be selected are illustrated. For example, the rated inventory of each target shipping container is 10 units of target merchandise. The total target tally containers are 8, and the current inventory of the 8 target tally containers is respectively 2 units, 3 units and 3 units in sequence. Among the candidate container combination sets that may be generated include, but are not limited to: the container combination set x1{ container combination A (2, 2) to be selected, container combination B (3, 3) }, and a set of container combinations x2 to be selected { container combinations A to be selected (2, 2), container combinations B to be selected (3, 3) }, wherein, since different target shipping containers with the same current inventory are treated as different individuals for the combined calculation, the set of candidate container combinations x2{ candidate container combination a (2, 2), candidate container combination B (3, 3) } corresponds to 13 sets of candidate container combinations.

The number of movements of the container includes the number of movements of the target container and the number of movements of the barrier container that blocks the target container. The moving times of the target tally containers refer to the moving times of the target tally containers from the storage area to the tally workstation, wherein one target tally container is moved to the tally workstation to calculate the target tally container to be moved once. The second preset condition is that the number of movements required for the container is minimal. Of course, the number of movements may be set to satisfy a predetermined value.

Specifically, in some embodiments, the partitioning unit is specifically configured to: generating a plurality of initial container combination sets according to the current inventory and the rated inventory of each target tally container, wherein each initial container combination set comprises at least two container combinations to be selected, each container combination to be selected comprises n target tally containers, and each container combination to be selected comprises the plurality of target tally containers and is not repeated; and screening out a container combination set with the full storage quantity and/or the empty quantity meeting a third preset condition from the container combination sets as a container combination set to be selected, wherein the full storage quantity is the quantity of target tally containers with the current inventory quantity reaching the rated inventory quantity after the tally is completed, and the empty quantity is the quantity of the empty target tally containers after the tally is completed. The third preset condition is that the sum of the full storage quantity is maximum and/or the empty quantity is maximum, or the third preset condition can also be that the full storage quantity is maximum preferentially and then the empty quantity is maximum.

For example, the rated inventory of each target shipping container is 10 units of target merchandise. The total target tally containers are 8, and the current inventory of the 8 target tally containers is respectively 2 units, 3 units and 3 units in sequence. The computer is adopted for continuous exhaustion, and various initial container combination sets are finally obtained, initial container combination set x1{ candidate container combination A (2, 2), candidate container combination B (3) 3, 3) } an initial container combination set x2{ alternate container combination A (2, 2) }, the container combination to be selected B (3, 3) }, the initial container combination set x2{ the container combination to be selected a (2, 2), the container combination to be selected B (2, 3), the container combination to be selected C (2, 3) }. Screening to maximize the number of full memory, then the initial container combination set x1{ the candidate container combination a (2, 2), the candidate container combination B (3, 3 ] 3) the initial container combination set x2{ the candidate container combination a (2, 2) as the candidate container combination set. Of course, the same thing can screen out the container combination set to be selected with the largest empty number.

The generating module 403 is configured to allocate the target goods in each target container combination to m target tally containers in the target container combination, so as to generate a tally scheme, where m is a positive integer less than or equal to the number of target tally containers included in the target container combination. The operation of the tallying is performed at a tallying workstation, and the goal is to distribute more goods 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 a specific implementation process, the generating module 403 is configured to: and distributing the target goods in at least one target tally container with smaller current inventory in each target container combination into m target tally containers with larger current inventory.

Wherein, in some embodiments, the generating module 403 comprises: the device comprises a distribution unit, a first judging unit, an ending unit and a circulating unit. The distribution unit is used for distributing target commodities in the target tally containers with the smallest current inventory in the target container combination to other target tally containers with less than full containers in the target container combination according to a preset priority order for each target container combination; the preset priority order is the order from big to small according to the current inventory, and when the target inventory is distributed, the target commodities in the target tally container with the smallest current inventory are preferentially distributed to the target tally container with the larger current inventory until the target tally container with the larger current inventory is full. And the first judging unit is used for judging whether the target tally container with the smallest current inventory in the target container combination is empty after the distribution operation is finished. And the ending unit is used for ending the tally corresponding to the target container combination if the target container combination is not empty. And the circulation unit is used for deleting the empty target tally containers from the target container combination and returning to the distribution unit so that the distribution unit performs distribution of 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 will be appreciated that in some embodiments, the generation module 403 is specifically configured to: for each target container combination, distributing target goods in a target tally container with the smallest current inventory in the target container combination to one or more other target tally containers in the target container combination until the target goods in the target tally container with the smallest current inventory are distributed or the other target tally containers in the target container combination are full; and the target goods in the other target tally container with the smallest storage amount in the target container combination are continuously distributed to one or more other target tally containers which are not fully contained in the target container combination after the target goods in the target tally container with the smallest storage amount are distributed.
