In the embodiment of the invention, determining the maximum inventory of the object according to the attribute information and the available inventory capacity of the object may include: acquiring attribute information of an article, wherein the attribute information of the article comprises a predetermined quantity threshold value and a predetermined volume; determining a maximum inventory of items that meet the following conditions: the maximum inventory of items is greater than or equal to the quantity threshold for the item; the sum of the item inventory ratios of all items is minimal; the sum of the total volumes of all the articles is less than or equal to the available storage capacity; wherein the item inventory ratio refers to the ratio of the item quantity threshold to the maximum inventory quantity of the item; total volume refers to the product of the volume of an individual item and the maximum inventory of that item. Wherein the available storage capacity is the product of the physical storage capacity and the available coefficient, and the available coefficient is a positive number not exceeding 1, and can be continuously adjusted according to the historical storage capacity data. In the e-commerce field, the predetermined quantity threshold may include, but is not limited to, predicted sales information for the item. In the prior available stock capacity, the embodiment of the invention determines the maximum stock quantity which is as close to a quantity threshold value (which can be referred to as the predicted sales quantity in the field of electronic commerce) as possible on the basis of ensuring that the maximum stock quantity of each article is larger than the predicted sales quantity, thereby avoiding the problem of inaccurate and unreasonable maximum stock quantity caused by manually setting the maximum stock quantity according to an empirical value in the prior art; the embodiment of the invention more reasonably and accurately determines the maximum inventory of the articles, lays a foundation for the subsequent determination of the demand of the articles, and improves the working efficiency.
Taking the example of placing articles on a picking area of a warehouse in the e-commerce field, the maximum stock quantity of the articles in the picking area is calculated. And determining the maximum stock quantity of the qualified articles in the picking area according to the available stock capacity of the picking area and the predicted sales quantity of the articles, namely determining the maximum stock quantity of each article in the picking area, which minimizes the sum y of the stock ratios of the articles of all the articles, under the condition that the conditions (1) and (2) are met.
Condition (1): the predicted sales quantity of the item i is less than or equal to the maximum stock quantity of the item i in the picking area;
condition (2):
wherein available inventory capacity of the pick area = physical inventory capacity of the pick area x availability factor;
n is the number of items that need to be put on shelf in the pick zone.
For example: the stock capacity of the picking area is 20m 3 The usable coefficient is 0.8, and the articles a and B are to be put on the shelf. The predicted sales of item a is 1 and the predicted sales of item B is 2. The volume of the article A is 3m 3 The volume of the article B is 4m 3 . The specific process of determining the maximum inventory of items A and B in the pick zone is as follows:
the available stock capacity of the picking area is 20m 3 ×0.8＝16m 3 . A. The maximum stock quantity a and B of the B in the picking area are respectively more than or equal to the predicted sales quantity, namely a is more than or equal to 1, and B is more than or equal to 2. The sum of the total volumes of the articles A and the articles B is smaller than or equal to the available storage capacity of the picking area, and a and B are positive integers which are larger than or equal to 0, namely 3a+4b is smaller than or equal to 16. Solving for the minimum of the sum of the item inventory ratios of item A and item B, i.e
TABLE 1
As shown in Table 1, because the available inventory capacity of the picking area is 16m 3 The volume of the article A is 3m 3 Object of the inventionThe volume of product B is 4m 3 Therefore, 3a+4b is less than or equal to 16, so that under the condition that the sum of the inventory ratios of the articles is minimum, the maximum inventory amount of the article A in the picking area is 2, and the maximum inventory amount of the article B in the picking area is 2.
In the embodiment of the invention, the maximum stock quantity of the article is determined according to the attribute information of the article and the available stock capacity, and the method further comprises the following steps: the attribute information of the article also comprises a storage type corresponding to the article; acquiring the volume of the storage location and the article corresponding to the storage location type; if the total volume of the articles corresponding to the storage type is larger than the volume of the storage, then: determining the correction priority of the articles according to the sequence of the library threshold difference values of the articles from large to small; correcting the maximum stock quantity of the articles according to the sequence of the correction priority from high to low until the total volume of the articles corresponding to the storage type is smaller than or equal to the volume of the storage; wherein the library threshold difference value refers to a difference between a maximum inventory amount of an item and a quantity threshold value of the item. An item may correspond to at least one storage type, and a storage type may also correspond to at least one item; the corresponding relation between the article and the storage type is preset. According to the embodiment of the invention, under the condition that the maximum inventory of the articles is determined, the maximum inventory of the articles is optimized according to different types of the corresponding storage positions of the articles of different types and by combining the volumes of the storage positions, so that the maximum inventory of the articles is more reasonable and accurate, errors in the process of loading the articles on the shelf are reduced, the problem of multiple subsequent replenishment is avoided, and the working efficiency is improved.
And acquiring the articles with the bound storage position types (namely the goods shelf types), and ordering the storage positions from large to small according to the volumes under the goods shelf types corresponding to the articles, wherein the articles are ordered from large to small according to the product of the maximum stock quantity and the volumes of the articles. Wherein, the volume of the special-shaped product is the product of the actual volume and the coefficient value, and the coefficient value is continuously corrected according to the history record. A single storage location may be defined to store a number of items of 5. And (3) according to the sequence, matching one by one, and if the current storage volume is exceeded, disassembling the storage and placing until all the articles are placed. If the articles are not placed, sorting the articles according to the library threshold difference value from large to small, starting to gradually reduce the maximum inventory, and gradually trimming the articles until the articles can be placed, so that the corrected maximum inventory and the matched goods shelf types of the articles are obtained.
For example: the article X and the article Y can be placed on two shelves of the attic partition board A and the attic partition board B, namely the article X corresponds to the attic partition board A and the attic partition board B; and the article Z needs to be placed on the shelf of the attic tray C, and the article Z corresponds to the attic tray C.
The predicted sales of item X was 5, the maximum inventory was 6, and the volume was 4m 3 ；
The predicted sales of item Y was 3, the maximum inventory was 5, and the volume was 2m 3 ；
The predicted sales of item Z was 10, the maximum inventory was 10, and the volume was 10m 3 。
The goods picking area comprises: 2 attic trays C, each 40m in volume 3 ；
1 attic partition A, each volume of 1m 3 ；
3 attic partitions B each having a volume of 10m 3 。
The items are ordered from large to small by the product of their maximum inventory and the volume of the items, with the result that: article Z100m 3 >Article X24m 3 >Article Y10m 3 。
The goods Z are preferably placed, the goods shelf of the goods Z is an attic tray C, and the total volume is 80m 3 First, 4 trays were placed on one tray, and another 4 trays were placed on the second tray. The last 2 items Z are not available for attic pallet c and are subtracted directly from the maximum inventory.
The article X can be placed on two goods shelves of the attic partition board A and the attic partition board B, the maximum stock volume of the article X is larger than the volume of the attic partition board A and smaller than the volume of the attic partition board B, and the article X is temporarily placed on the attic partition board B.
The article Y is smaller than the residual volume of the attic partition board B and larger than the volume of the attic partition board A and is not placed down.
If the stock threshold difference of the article X is 1 and the stock threshold difference of the article Y is 2, the maximum stock quantity of the article Y is firstly tried to be corrected to be 4, the maximum stock quantity of the article X is unchanged, and the placement is found to be unchanged. The maximum stock of the trial correction article X is 5, the maximum stock of the article Y is unchanged, and it is found that the article X can be placed on the attic partition b, and the article Y can be placed on the attic partition b. Finally, the maximum stock quantity of the corrected article X is 5, the maximum stock quantity of the article Y is 5, and the maximum stock quantity of the article Z is 8.
