Description

storage allocation method and device

Technical Field

the invention relates to the field of computers, in particular to a storage allocation method and device.

background

With the rapid development of electronic commerce, the demand of users for logistics distribution is also increasing. In order to deliver items to a user in the shortest amount of time, a service provider places a large number of pre-bins around the user, and when the remaining inventory of an item in a pre-bin is less than the safety inventory, the pre-bin needs to be restocked to the target inventory. The front-end warehouse is a logistics warehousing node which is closest to a user and is arranged at the front end in a warehousing and logistics system inside a service provider. Whether to replenish goods for thousands of front bins in time and scientifically directly influences the operation of a service provider.

In the prior art, the realization process of replenishing goods to the front bin is as follows: the supplier distributes the articles to the central bin in a centralized way, and the service provider transfers the articles from the central bin to each front bin in sequence according to the sales activity of the front bins. The central warehouse can be classified into a central distribution center and a regional distribution center, and is mainly used for receiving various kinds of large-batch cargos provided by suppliers, and delivering the matched cargos to logistics companies or designated organizations according to the requirements of the demand parties after the cargos are subjected to storage, sorting, distribution, circulation processing, information processing and other operations.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

when the residual stock of the central bin can not meet the replenishment requirements of all the front bins for a long time, the front bins with low sales activity can not be allocated all the time because the replenishment requirements of the front bins with high sales activity are preferentially met in the prior art, and the shortage risk can be caused if manual intervention is not performed; when the residual inventory of the central bin is larger than the replenishment demands of all the front bins, the prior art only meets the replenishment demands of the front bins and does not process the excess inventory, so that the articles which have short expiration date and are not easy to store for a long time cannot be sold quickly, and finally the articles deteriorate and are lost.

Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The following explains the words involved in the present invention.

and (4) remaining stock: is the current inventory of items in the front bin or the center bin.

Safety stock: safety stock-average sales per day x days of safety stock. The number of days for safety stock is set by firstly considering the arrival period after placing orders to suppliers and secondly considering the buffer stock prepared by influencing the order demand due to uncertain factors (such as sudden mass orders or delayed delivery of suppliers), so as to ensure the normal sale of the stock in the period from the order placing to the delivery of the goods to the front warehouse. When the remaining stock of a certain article in the front bin is smaller than the safety stock, the article has the risk of stock shortage and needs to be replenished; when the residual stock of the article in the front bin is more than or equal to the safety stock, the article has no risk of stock shortage and does not need replenishment.

target inventory: is the inventory expected to be reached by the item in the front bin, which is greater than the safety inventory. When the goods with the shortage risk in the front bin are replenished, the goods need to be replenished to the target stock.

Stock to be distributed: is the inventory of items to be dispensed in the central bin that is less than or equal to the remaining inventory of the central bin.

Fig. 1 is a schematic diagram illustrating main steps of a warehouse allocation method according to an embodiment of the present invention. As shown in fig. 1, the warehouse allocation method according to the embodiment of the present invention mainly includes the following steps:

step S101: and calculating the suggested transfer amount of the articles in each front bin, and summing the suggested transfer amounts to obtain the expected transfer amount. Wherein the proposed transfer amount is equal to a difference between the target inventory and the remaining inventory. And acquiring the residual inventory and the safety inventory of the articles in each front bin, comparing the size of the residual inventory and the safety inventory of each front bin, and if the residual inventory of a certain front bin is smaller than the safety inventory, replenishing the inventory of the front bin to the target inventory. And after the suggested allocation amount of a certain article in each front cabin is calculated, summarizing the front cabins with the suggested allocation amount larger than 0 to obtain the expected allocation amount.

step S102: and acquiring the stock to be distributed of the goods in the central bin, and comparing the stock to be distributed with the expected allocation amount. And comparing the inventory to be distributed of the articles in the central bin with the expected allocation amount calculated in the step S101 to judge whether the inventory to be distributed of the central bin can meet the replenishment requirement of each front bin with the shortage risk. The front bin with the shortage risk refers to a front bin with the remaining stock of the articles smaller than the safety stock, and the front bin is collectively called a first-stage front bin in the embodiment of the invention.

step S103: when the inventory to be distributed is smaller than the expected allocation amount, allocating the inventory to be distributed to each first-level front bin according to a target inventory proportion. And the target inventory proportion is calculated according to the sum of the residual inventories of the front bins, the sum of the target inventories and the inventory to be distributed. If the inventory to be distributed is smaller than the expected allocation amount, which indicates that the inventory to be distributed in the central bin is insufficient, determining a new suggested allocation amount according to the calculated target inventory proportion, and allocating all the inventory to be distributed to the first-stage front-end bin according to the new suggested allocation amount; if the inventory to be distributed is larger than the expected transfer amount, which indicates that the inventory to be distributed in the central bin is excessive, the inventory to be distributed can be transferred to a first-stage front bin, and then all front bins of which the inventory is less than or equal to the target inventory are replenished according to the transaction activity, so that the transferred inventory to be distributed is 0; if the inventory to be distributed is equal to the desired transfer amount, each first-level pre-silo may be directly restocked to the corresponding target inventory.

After the comparison in step S102, how to allocate all the inventory to be allocated to each first-level front bin will be described in detail when the inventory to be allocated in the central bin is insufficient, that is, the inventory to be allocated in the central bin is smaller than the expected allocation amount of the front bins.

Fig. 2 is a schematic flow chart of a warehouse allocation method when the to-be-distributed inventory is insufficient according to an embodiment of the present invention. As shown in fig. 2, a warehouse allocating method in an embodiment of the present invention mainly includes the following steps:

and step S201, determining the average sales volume of the articles in each front bin in unit time, wherein the average sales volume in unit time is the average sales volume of a certain article in the front bin in unit time, such as the average sales volume per day, the average sales volume per month and the like, and assuming that the sales volume of the ith front bin in m days is S _i,j, the average sales volume per day S _avg,i is:

And S202, calculating the sum of the recommended allocation amounts of all the preposed bins with the average sales amount per unit time being more than or equal to a preset threshold value, presetting a threshold value T ₁, finding out all the preposed bins with the average sales amount per unit time being more than or equal to the T ₁, wherein the preposed bins are uniformly called second-stage preposed bins in the embodiment of the invention, finding out all the preposed bins with the average sales amount being more than or equal to S _avg,i < T ₁ in the embodiment of the invention, and the preposed bins are uniformly called third-stage preposed bins in the embodiment of the invention.

Step S203: comparing the inventory to be distributed with the sum of the suggested allocation amounts, and executing the step S204 when the inventory to be distributed is smaller than the sum of the suggested allocation amounts; otherwise, step S208 is performed. The step is used for judging whether the stock to be distributed of the central bin can meet the replenishment requirement of the second-level front bin, if not, executing the step S204 to the step S207 to replenish each second-level front bin; if so, steps S208 through S212 are performed to restock each of the second and third stage pre-pods.

Step S204: and acquiring the sum of the remaining stocks of the articles in all the second-stage front bins and the sum of the target stocks, and executing the step S205. And acquiring the remaining inventory and the target inventory of the articles in each second-stage front bin, summing all the remaining inventory to obtain the sum of the remaining inventory of all the second-stage front bins, and summing all the target inventory to obtain the sum of the target inventory of all the second-stage front bins.

Step S205: and calculating a target inventory proportion according to the sum of the remaining inventory, the sum of the target inventory and the inventory to be distributed. The calculation formula of the target inventory proportion in the step is as follows:

T＝(M+P)/N

step S206: and determining the newly proposed allocation amount of each second-stage preposed bin according to the target inventory, the residual inventory and the target inventory proportion of each second-stage preposed bin. Firstly, multiplying the target inventory of each second-stage front-end bin by the target inventory proportion respectively to obtain a new target inventory of each second-stage front-end bin; and then, the new target inventory of each second-stage preposed bin is respectively differenced with the corresponding residual inventory to obtain the newly proposed allocation amount of each second-stage preposed bin.

Assuming that the target inventory of the ith front-end bin is S _t,i, the new target inventory is S _tnew,i, and the remaining inventory is S _u,i, the new target inventory of the ith front-end bin is S _tnew,i ═ S _t,i × T, and the new proposed allocation amount E _i ═ S _tnew,i -S _u,i.

step S207: and allocating the to-be-allocated inventory to each second-stage preposed bin according to the newly proposed allocation amount of the second-stage preposed bins, and ending the process. Through the steps S204 to S207, the stock to be distributed is proportionally split to all the second-level front bins, each second-level front bin can be guaranteed to be replenished, and the stock shortage risk is reduced.

and S208, allocating the stock to be allocated to each second-level front bin according to a preset replenishment stock, and executing S209, wherein the replenishment stock is any value between the safety stock and the target stock, and according to the replenishment stock, replenishing all the front bins of which the quantity is more than or equal to T ₁ in S _avg,i.

step S209: and acquiring the sum of the remaining stocks of the items in all the third-stage front bins and the sum of target stocks. And acquiring the remaining inventory and the target inventory of the articles in each third-level front bin, summing all the remaining inventory to obtain the sum of the remaining inventory of all the third-level front bins, and summing all the target inventory to obtain the sum of the target inventory of all the third-level front bins.

Step S210: and calculating a new target inventory proportion according to the sum of the remaining inventory, the sum of the target inventory and the inventory to be distributed. The calculation formula of the new target inventory proportion in the step is as follows:

T′＝(M′+P′)/N′

In the formula, T 'is a new target inventory proportion, M' is the sum of the remaining inventory of the articles in all the third-level front bins, N 'is the sum of the target inventory of the articles in all the third-level front bins, and P' is the remaining inventory to be distributed after the replenishment of the second-level front bins is completed.

Step S211: and determining the newly proposed allocation amount of each third-level front-end bin according to the target inventory, the residual inventory and the new target inventory proportion of each third-level front-end bin. Firstly, multiplying the target inventory of each third-stage front bin by the third target inventory ratio respectively to obtain a new target inventory of each third-stage front bin; and then, the new target inventory of each third-stage preposed bin is respectively differed from the corresponding residual inventory to obtain the newly proposed allocation amount of each third-stage preposed bin.

step S212: and allocating the remaining stock to be distributed after allocation to each third-level preposed bin according to the newly allocated allocation amount of the third-level preposed bin, and ending the process. Through the steps S208 to S212, each second-level front bin is replenished according to the replenishment stock, and then the remaining stock to be distributed after being allocated in the step S208 is proportionally split to all third-level front bins, so that each third-level front bin can be replenished, and the shortage risk is reduced.

Fig. 3 is a schematic flow chart of a warehouse allocation method when the inventory to be allocated is insufficient according to the second embodiment of the present invention, in this embodiment, the threshold T ₁ is 0, that is, the specific implementation process of allocating all the inventory to be allocated to the first-stage front warehouse is not related to the average sales amount per unit time, as shown in fig. 3, the warehouse allocation method when the inventory to be allocated is insufficient according to the second embodiment of the present invention mainly includes the following steps:

Step S301: and acquiring the sum of the remaining stocks of the articles in all the first-stage front bins and the sum of target stocks. And acquiring the remaining inventory and the target inventory of the articles in each first-level front bin, summing all the remaining inventory to obtain the sum of the remaining inventory of all the first-level front bins, and summing all the target inventory to obtain the sum of the target inventory of all the first-level front bins.

Step S302: and calculating the target inventory proportion of the first-stage front bin according to the sum of the remaining inventory, the sum of the target inventory and the inventory to be distributed. In the step, a calculation formula of the target inventory proportion of the first-stage front bin is as follows:

T″＝(M″+P)/N″

In the formula, T ' is the target inventory proportion of the first-stage front bins, M ' is the sum of the remaining inventory of the articles in all the first-stage front bins, N ' is the sum of the target inventory of the articles in all the first-stage front bins, and P is the inventory to be distributed.

Step S303: and determining the newly-proposed allocation amount of each first-stage preposed bin according to the target inventory, the residual inventory and the target inventory proportion of the first-stage preposed bin. In the step, the newly created call allocation amount of each front-end bin in the first-stage front-end bin needs to be calculated, so that each front-end bin needs to be traversed circularly, and the method is specifically realized as follows:

(1) Multiplying the target inventory of the current preposed bin in the first-stage preposed bin by the target inventory proportion of the first-stage preposed bin to obtain a new target inventory of the current preposed bin;

(2) The new target inventory of the current preposed bin is differentiated from the corresponding residual inventory to obtain a newly proposed allocation amount of the current preposed bin;

(3) judging whether the next front bin is the last front bin of the first-stage front bin, if so, executing the step S304; if not, performing (1) with the next leading bin as the current leading bin.

Step S304: and allocating the stock to be distributed to each first-stage preposed bin according to the newly proposed allocation amount of the first-stage preposed bin. Through the steps S301 to S304, the stock to be distributed is proportionally split to all the first-level front bins, each first-level front bin can be guaranteed to be replenished, and the stock shortage risk is reduced. Through the process, each preposed bin with the shortage risk can be replenished, and the problem that the preposed bin with low sales activity cannot be replenished when the central bin is not in stock for a long time is solved.

In the following, when the inventory to be allocated of the central bin is excessive, i.e. the inventory to be allocated of the central bin is greater than the expected allocation amount of the front bins after the comparison in step S102, how to allocate all the inventory to be allocated to at least one front bin will be described in detail.

Fig. 4 is a schematic flow chart of a warehouse transfer method when the inventory to be distributed is excessive according to a third embodiment of the present invention. As shown in fig. 4, the third warehousing method for excess inventory to be distributed according to the embodiment of the present invention mainly includes the following steps:

Step S401: and allocating the stock to be distributed to each first-stage front bin according to a preset replenishment stock. Wherein the replenishment inventory is any value between the safety inventory and the target inventory. In a preferred embodiment, each of the first-level pre-bins is restocked to a corresponding target inventory.

Step S402: and calculating the transaction activity of each fourth-stage front bin according to preset parameters. The fourth-stage front bin is the front bin in which the remaining stock of the articles is less than or equal to the target stock after the allocating in the step S401. In this embodiment, all the front bins are divided into two types, the first type is a front bin with a remaining stock smaller than the safety stock (i.e., a first-level front bin), and the second type is a front bin with a remaining stock greater than or equal to the safety stock and less than or equal to the target stock. The second-class front bin and the front bin with the residual stock less than or equal to the target stock in the first-class front bin after the allocation in the step S401 form a fourth-class front bin. Wherein, the calculation formula of the transaction activity is as follows:

in the above formula, the parameter of the transaction activity considers the distance between the central bin and the front bin in addition to the average sales per unit time. For the articles with short preservation time, such as fresh articles, if the articles are placed for allocation in the next day, the quality of the articles is poor, even the articles are damaged, and the loss is caused. Therefore, when calculating the transaction activity, the distance between the central bin and the front bin can be considered, and the closer the distance is, the larger the average sales amount per unit time is, the better the restocking can be prioritized.

step S403: and allocating the inventory to be allocated left after allocation to at least one fourth-stage front bin according to the transaction activity, so that the inventory to be allocated is 0. According to the step, the fourth-stage front bin can be sequentially replenished according to the transaction activity until the stock to be distributed of the central bin is 0 (corresponding to the fourth embodiment); or, according to the replenishment proportion, replenishment may be performed on each fourth-stage front bin, and the stock to be allocated in the central bin after completion of replenishment is also 0 (corresponding to the fifth embodiment). The specific implementation of this step is described in detail below with reference to example four and example five.

Example four:

(1) And sequencing all the fourth-stage front bins according to the transaction activity. In a preferred embodiment, all the fourth-stage front bins are sorted according to the sequence of the transaction liveness from large to small.

(2) and sequentially allocating the remaining stocks to be distributed after allocation to the fourth-stage front bin according to the sequencing result and a preset first allocation quantity. The first dialing number is preset according to requirements, and may be 1, 2, 3, and the like. Assuming that the first transfer amount is 1, the remaining stocks to be distributed after the transfer in step S401 are distributed to the fourth-level front bin one by one according to the sequence of the transaction liveness from large to small until the stocks to be distributed are 0.

example five:

(1) And multiplying the remaining stock to be distributed after allocation and the transaction activity after normalization to obtain a replenishment proportion. The normalized transaction liveness is:

In the formula, A' _i is the normalized transaction activity, and n is the number of all the fourth-stage front bins.

Assuming that the inventory to be distributed remaining after the allocation in step S401 is P ", and the replenishment proportion of the ith fourth-stage front bin is C _i, C _i is P ″ × a' _i.

(2) And transferring the remaining stock to be distributed after transferring to each fourth-stage front bin according to the replenishment proportion. And distributing the P' into the corresponding fourth-stage front bin according to the replenishment proportion of each fourth-stage front bin.

In the sixth embodiment, because the average sales per unit time of some front bins are too small, the goods can be filled without being blocked, at this time, a goods filling threshold T ₂ can be preset, and the front bins with the average sales per unit time smaller than the goods filling threshold T ₂ are not filled with goods, the method is concretely realized by firstly executing the step S401, then filtering out the front bins with the average sales per unit time smaller than T ₂ in the fourth front bin, taking the rest front bins as the fourth front bins, and then sequentially executing the steps S402 and S403.

In the third embodiment, all the front bins are classified into two types, but for the front bin having the remaining stock equal to the target stock, if replenishment is performed, there is a high possibility that high turnover will be caused, and therefore, replenishment of the front bin which does not cause high turnover needs to be performed preferentially. In the seventh embodiment, all the front bins are classified into three types, the first type is a front bin having a remaining stock smaller than the safety stock (i.e., the first-stage front bin), the second type is a front bin having a remaining stock equal to or larger than the safety stock and smaller than the target stock (collectively referred to as the fifth-stage front bin in the embodiment of the present invention), and the third type is a front bin having a remaining stock equal to the target stock (collectively referred to as the sixth-stage front bin in the embodiment of the present invention). For the first-stage front bin, if the front bin is not timely allocated, the risk of shortage of goods exists; for the fifth-level front bin, although the risk of inventory does not exist, high turnover cannot be caused when the goods are replenished to the target inventory; for the sixth-stage front bin, since its remaining stock is equal to the target stock, it is highly likely to cause high turnover if restocking.

Fig. 5 is a schematic main flow chart of a warehousing transfer method when the inventory to be allocated is excessive according to a seventh embodiment of the present invention. As shown in fig. 5, a seventh warehousing transferring method for surplus inventory to be distributed in the embodiment of the present invention mainly includes the following steps:

Step S501: and allocating the stock to be distributed to each first-stage front bin according to a preset replenishment stock. In a preferred embodiment, each first-level front bin is replenished to the corresponding target inventory, and since the inventory to be replenished is larger than the expected transfer amount, the inventory of the central bin is still surplus after the replenishment in the step is completed.

Step S502: and calculating the transaction activity of each fifth-stage front bin according to preset parameters. In a preferred embodiment, the weight β may be set to 0, i.e. the transaction activity is only related to the average sales per unit time, and the transaction activity is the sales activity.

Step S503: and sequencing all the fifth-stage front bins according to the magnitude of the transaction activity. In a preferred embodiment, all the fifth-stage front bins are sorted in descending order of sales activity.

step S504: and sequentially transferring the remaining stock to be distributed after transferring to the fifth-level front-end bin according to the sequencing result and a preset second transferring quantity, so that the remaining stock of each fifth-level front-end bin after transferring is the target stock, or the stock to be distributed is 0. The second dialing number is preset according to requirements, and may be 1, 2, 3, and the like. Assuming that the second allocation quantity is 1, allocating the remaining stock to be allocated after the allocation in step S501 to the fifth-level front bins one by one in the order from large sales activity to small sales activity until the remaining stock of each fifth-level front bin is the target stock or the stock to be allocated is 0.

step S505: judging whether the inventory to be distributed of the central bin is 0 or not, if not, executing a step S506; if so, the flow ends. When all the fifth-level front bins are allocated as the corresponding target inventory and the allocated inventory to be distributed is greater than 0, it is indicated that the inventory to be distributed of the central bin is still surplus, and step S506 is executed.

Step S506: merging the first, fifth, and sixth stage pre-bins to generate the fourth stage pre-bin.

Step S507: and calculating the transaction activity of each fourth-stage front bin according to preset parameters. In the step, only the transaction activity of the first-stage front bin and the sixth-stage front bin needs to be calculated. In a preferred embodiment, the weight β is still set to 0, and only the sales activity of the first and sixth stage pre-bins need to be calculated.

step S508: and transferring the rest inventory to be distributed after transfer to at least one fourth-stage front bin according to the transaction activity and a preset third transfer quantity so as to enable the inventory to be distributed to be 0. The third dialing number is preset according to requirements, and may be 1, 2, 3, and the like. Assuming that the third allocation amount is 1, allocating the remaining stocks to be allocated after the allocation in step S504 to the fourth-level front bin one by one in the order from large sales activity to small sales activity until the stocks to be allocated are 0, that is, all the stocks to be allocated are allocated to the front bin. The excess inventory of the central bin can be distributed entirely to the front bins by the above process, so that items with short expiration dates are all available for sale at the first time, rather than being retained in the central bin.

according to the warehouse allocating method, the to-be-allocated inventory of the central warehouse is compared with the expected allocating amount of all the front warehouses, and when the to-be-allocated inventory is smaller than the expected allocating amount, all the to-be-allocated inventory is allocated to the front warehouses of which the remaining inventory is smaller than the safety inventory according to the target inventory proportion, so that the shortage risk of the front warehouses caused by insufficient to-be-allocated inventory is reduced; by introducing the average sales per unit time and the target inventory proportion, when the inventory to be distributed is insufficient, the pre-warehouse with the average sales per unit time greater than or equal to the preset threshold value is preferably replenished; by using the target inventory proportion to adjust the suggested allocation amount, each first-stage front bin can be replenished, and the shortage risk is reduced; by introducing the transaction activity, when the inventory to be distributed is excessive, the front bin with the residual inventory less than or equal to the target inventory can be replenished; by introducing the replenishment proportion, when the stock to be distributed is excessive, all the preposed bins with the surplus stock less than or equal to the target stock can be replenished.

fig. 6 is a schematic diagram of main modules of the warehousing transfer device according to the embodiment of the invention. As shown in fig. 6, the warehousing allocating device 600 of the embodiment of the present invention mainly includes:

the calculation module 601 is configured to calculate suggested allocation amounts of the articles in each pre-bin, and sum the suggested allocation amounts to obtain an expected allocation amount. Wherein the proposed transfer amount is equal to a difference between the target inventory and the remaining inventory. And acquiring the residual inventory and the safety inventory of the articles in each front bin, comparing the size of the residual inventory and the safety inventory of each front bin, and if the residual inventory of a certain front bin is smaller than the safety inventory, replenishing the inventory of the front bin to the target inventory. And after the suggested allocation amount of a certain article in each front cabin is calculated, summarizing the front cabins with the suggested allocation amount larger than 0 to obtain the expected allocation amount.

A comparing module 602, configured to obtain an inventory to be allocated of the item in the central warehouse, and compare the inventory to be allocated with the expected allocation amount. The inventory to be distributed of the articles in the central bin is compared with the expected allocation amount calculated by the calculation module 601 to judge whether the inventory to be distributed of the central bin can meet the replenishment demand of each front bin with the shortage risk. The front bin with the shortage risk refers to a front bin with the remaining stock of the articles smaller than the safety stock, and the front bin is collectively called a first-stage front bin in the embodiment of the invention.

and the allocating module 603 is configured to allocate all the stocks to be allocated to the first-stage front warehouse according to the target stock proportion when the stocks to be allocated are smaller than the expected allocating amount. And the target inventory proportion is calculated according to the sum of the residual inventories of the front bins, the sum of the target inventories and the inventory to be distributed. If the inventory to be distributed is smaller than the expected allocation amount, which indicates that the inventory to be distributed in the central bin is insufficient, determining a new suggested allocation amount according to the calculated target inventory proportion, and allocating all the inventory to be distributed to the first-stage front-end bin according to the new suggested allocation amount; if the inventory to be distributed is larger than the expected transfer amount, which indicates that the inventory to be distributed in the central bin is excessive, the inventory to be distributed can be transferred to the first-stage front bin, and then all the front bins of which the inventory is less than or equal to the target inventory are replenished according to the transaction activity, so that the transferred inventory to be distributed is 0. If the inventory to be distributed is equal to the desired transfer amount, each first-level pre-silo may be directly restocked to the corresponding target inventory.

In addition, the warehousing transferring device 600 of the embodiment of the present invention may further include: an inventory excess transfer module and an optimization module (not shown in FIG. 6). And the inventory surplus allocation module is used for allocating all the inventory to be allocated to at least one preposed bin according to the category of each preposed bin when the inventory to be allocated is larger than the expected allocation amount, and the specific allocation process is as described above. The optimization module is used for calculating the transaction activity of each fifth-stage front bin according to preset parameters; the fifth-stage front bin is a front bin, wherein the residual stock of the articles is greater than or equal to the safety stock and is smaller than the target stock; sorting all the fifth-stage front bins according to the transaction activity; according to the sequencing result and a preset second allocation quantity, sequentially allocating the remaining stocks to be allocated after allocation to the fifth-level front-end bins, so that the remaining stocks of each fifth-level front-end bin after allocation are the target stocks or the stocks to be allocated are 0; when all the fifth-level front bins are allocated to corresponding target stocks and the allocated stocks to be distributed are larger than 0, combining the first-level front bins, the fifth-level front bins and the sixth-level front bins to generate the fourth-level front bins; wherein the sixth level front bin is a front bin where the remaining inventory of the item is equal to the target inventory.

as can be seen from the above description, by comparing the inventory to be distributed of the central bin with the expected allocation amounts of all the front bins, when the inventory to be distributed is smaller than the expected allocation amount, the inventory to be distributed is allocated to the front bins with the remaining inventory smaller than the safety inventory according to the target inventory proportion, so that the shortage risk of the front bins caused by shortage of the inventory to be distributed is reduced; by introducing the average sales per unit time and the target inventory proportion, when the inventory to be distributed is insufficient, the pre-warehouse with the average sales per unit time greater than or equal to the preset threshold value is preferably replenished; by using the target inventory proportion to adjust the suggested allocation amount, each first-stage front bin can be replenished, and the shortage risk is reduced; by introducing the transaction activity, when the inventory to be distributed is excessive, the front bin with the residual inventory less than or equal to the target inventory can be replenished; by introducing the replenishment proportion, when the stock to be distributed is excessive, all the preposed bins with the surplus stock less than or equal to the target stock can be replenished.
