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.
In a warehouse, a carrier robot lifts a rack to a work station to perform operations such as warehousing and ex-warehouse of articles. As items are continuously removed from the warehouse, the distribution of the same items on the shelves will change.
For example, the remaining amount of the item on some shelves is zero but the item is not restocked, which results in that the number of shelves for storing the item in the warehouse is insufficient, and the shelves are contended for picking the item between the workstations, thereby affecting the delivery efficiency.
In order to meet the picking requirement of the workstation for the shelf on which the same item is placed, the following technical scheme in the embodiment of the invention can be adopted.
Referring to fig. 2, fig. 2 is a schematic diagram of a main flow of a method of allocating items according to an embodiment of the present invention, selecting a source shelf of an item among shelves of the item, sequentially shelving the items from the source shelf based on allocation scores of the items, and shelving the shelved items on a destination shelf. As shown in fig. 2, the method specifically includes the following steps:
s201, determining that the number of the shelves for placing the articles does not reach a first preset value and the maximum number of the articles placed on the shelves is larger than a second preset value, and taking the shelves for placing the articles with the maximum number as source shelves.
The picking requirement of the workstation cannot be met due to the fact that the number of the shelves for placing the same article is insufficient. Then need to tear open the zero tally, reduce the risk of robbing the goods shelves. That is, the part of the goods in the shelf in the warehouse where the goods are stored is put down and then put on the other shelf, thereby increasing the number of shelves where the goods are stored.
Referring to fig. 3, fig. 3 is a schematic flow chart of determining an origin shelf according to an embodiment of the invention. The method specifically comprises the following steps:
s301, whether the number of the shelves for placing the articles reaches a first preset value or not is judged.
Placing one or more items on the shelves first requires determining which items have shelves whose number does not meet the picking requirements of the workstation. As one example, the number M of shelves of an item s may be queried periodicallys. As another example, M may also be queried at the request of the clients. Wherein M issIs the number of shelves in the warehouse that actually store the item s. As one example, item s may be a red towel. The goods shelves for storing the red towels in the warehouse are a goods shelf A, a goods shelf B and a goods shelf C, and then M of the red towelssEqual to 3.
And MsCorresponding to the number of preset goods shelves
Figure BDA0002080068760000061
Figure BDA0002080068760000062
Is the number of preset shelves of the item s in the warehouse.
In one embodiment of the invention, the first predetermined value is set by
Figure BDA0002080068760000063
The determined parameter. As an example, if the number of days an item s has been in inventory in the warehouse is less than a threshold length of time and there is no export record, then
Figure BDA0002080068760000064
At least two. In the embodiment of the present invention, the threshold duration is exemplarily illustrated as 7 days. Can be based on actual needsAnd solving the set threshold duration. It will be appreciated that items s may be placed on at least 2 shelves to meet the picking requirements of the workstation with less than 7 days in stock in the warehouse and without an out-of-stock record.
As another example, an item s may need to be updated when the number of days in storage in a warehouse reaches a threshold length of time, or when a warehouse-out record exists, that is, the item s has been taken out of the warehouse
Figure BDA0002080068760000065
Figure BDA0002080068760000066
Is composed of CsAnd K. CsIs the maximum number of the items s in the plurality of the manifest within the past threshold time length, namely the concurrent amount of the items s, and if the items s have no ex-warehouse record within the past 7 days, Cs0. K is the number of stations for picking the item s.
As an example of this, it is possible to provide,
Figure BDA0002080068760000071
Figure BDA0002080068760000072
consider that each station requires a shelf of items s to meet the picking requirements of the station.
In one embodiment of the invention, the number of shelves on which the item is placed reaches a first threshold, indicating that the shelves for the item meet the picking requirements of the workstation, and then ends. If the number of shelves on which the item is placed does not reach the first threshold, it indicates that the shelves of the item are difficult to meet the picking requirement of the workstation, and S302 is executed.
In particular, the first preset value is a parameter determined by the number of preset shelves of the item. The first preset value may be determined based on a preset number of shelves for the item. As one example, the first preset value is proportional to the number of preset shelves of the item. Namely: the greater the number of preset shelves for an item, the greater the first preset value.
In the inventionIn one embodiment, according to a preset shelf factor α1And the number of preset shelves for the item, determine a first preset value. The first preset value is equal to
Figure BDA0002080068760000073
The number of shelves on which the items s are placed does not reach the first preset value,
namely:
Figure BDA0002080068760000074
wherein alpha is1Is a value of 1 or less and greater than 0. As an example, α1May be equal to 0.5.
In the above embodiment, whether the number of shelves of the item reaches the first preset value, that is, whether the picking requirement of the workstation is met, may be determined by presetting the shelf coefficient. The closer the preset shelf coefficient is set to 1, the looser the picking requirement of the workstation is judged to be met; in contrast, the closer the preset shelf factor setting is to 0, the more stringent the determination is made as to whether the picking requirements of the workstation are met. The larger the preset shelf factor setting is, the more items are marked to fail to meet the picking requirement of the workstation. Whether the goods meet the picking requirement of the workstation or not is reflected by the preset goods shelf coefficient.
S302, whether the maximum quantity of the goods placed on the shelf is larger than a second preset value or not.
In determining that the number of shelves of an item does not meet the picking requirements of the workstation, and that there are multiple shelves in the warehouse storing the item, it is necessary to select the source shelf of the item among the shelves of the item. The source shelf is a shelf that requires shelving items.
The maximum number of items placed on a shelf is the maximum number of items on the shelf. As an example, for an item s, the number of shelves on which the item s is placed is 3, namely, the shelf 1, the shelf 2, and the shelf 3. Wherein 2 articles s are placed on the shelf 1; 5 articles s are placed on the shelf 2; the shelf 3 is provided with 6 articles s. Then, the maximum number of shelf-placed items is 6, i.e., the number of shelf-3-placed items s.
The set of shelves for storing articles s is omegas，qisThe number of items s placed on the shelf i. The maximum number of shelf items s is:
Figure BDA0002080068760000081
the second preset value is a parameter determined by the number of recommended shelved items for the item. Specifically, the second preset value is proportional to the number of recommended shelved items of the item. The larger the number of recommended shelved items of the item is, the larger the second preset value is. Executing S303 if the maximum quantity of the articles placed on the shelf is greater than a second preset value; and if the maximum quantity of the articles placed on the shelf is less than or equal to a second preset value, the quantity of the articles on the shelf of the article is not enough, and the articles cannot be prepared, and then the process is finished.
In one embodiment of the invention, the recommended quantity of the shelved items is a parameter determined by a total quantity of the items ex-warehouse within a threshold time length, a preset number of shelves of the items, a maximum number of shelves capable of carrying the items, and a preset proportion of the quantity of the items ex-warehouse within the threshold time length, wherein the preset proportion of the quantity of the items ex-warehouse is equal to a product of the preset proportion and the quantity of the items ex-warehouse within the threshold time length.
Exemplary, recommended number of items on shelf for item s

Figure BDA0002080068760000091
Wherein Q issThe total quantity of the articles s which are delivered from the warehouse within the threshold duration; if the product is stored in warehouse for less than 7 days, QsIs the predicted value of the total delivery amount of 7 days.
Figure BDA0002080068760000092
And (4) the quantity of the articles s discharged from the warehouse in a preset proportion within the threshold duration. The threshold duration is 7 days, the ex-warehouse quantity of the articles s in the past 7 days is N, and the product of the preset proportion and N is rounded up
Figure BDA0002080068760000093
As an example, the preset ratio is equal to 90%.
Figure BDA0002080068760000094
The maximum number of the articles s that can be carried by the shelf is the maximum number of the articles s that can be stored on the shelf on the premise that the volume threshold value is not exceeded.
The second preset value is equal to
Figure BDA0002080068760000095
The maximum quantity of the goods placed on the goods shelf is greater than a second preset value, namely:
Figure BDA0002080068760000096
s303, taking the shelf on which the largest number of articles are placed as a source shelf.
If the formula (2) is satisfied,
Figure BDA0002080068760000097
then
Figure BDA0002080068760000098
Is the source shelf of the item s. As an example, if there are a plurality of
Figure BDA0002080068760000099
One can be randomly selected
Figure BDA00020800687600000910
As a source shelf. Alpha is alpha2Is a predetermined item coefficient, α2Is a value of 2 or less and greater than 0. As an example, α2Equal to 0.8.
In the above embodiment of fig. 3, the source shelf is determined by a preset item factor according to the maximum number of items placed on the shelf. The larger the preset item coefficient, the fewer shelves that satisfy equation (2). By presetting the item coefficients, the source shelf of the item can be selected among the shelves of the item.
S202, calculating a blending score of the goods to be blended among the shelves, wherein the blending score is determined based on the number of the shelves for placing the goods and the concurrency of the goods, and the concurrency of the goods is the maximum number of the goods in the plurality of goods lists in a preset time length.
Referring to fig. 4, fig. 4 is a schematic flow chart of shelving items and shelving items according to an embodiment of the invention, specifically including:
s401, calculating the allocation fraction of the goods to be allocated between the shelves.
The warehouse stores a plurality of articles, and one or more articles are placed on each shelf. There are multiple source racks in the warehouse, and for each source rack, it is necessary to lower the items and then place the lower items on the destination rack. The target shelf is a shelf for putting the article on the shelf. The target shelf is not placed with the goods on the lower shelf before the goods on the upper shelf and the lower shelf.
However, there are many items to be allocated in the warehouse, and the work station needs to put the items from the shelves according to the risk of the shelves for robbery.
In one embodiment of the invention, the risk of warfare is measured in terms of a deployment score. The smaller the allocation score is, the greater the risk of goods shelf robbery is; correspondingly, the greater the blending score, the less the risk of goods and goods shelves for robbery. The blending score is a numerical value determined based on the number of shelves of the item and the amount of concurrency of the item. Specifically, the blending score is proportional to the number of shelves of the item and inversely proportional to the amount of concurrency of the item.
In one embodiment of the invention, the blending score is equal to the product of the shelf parameter and the preset shelf weight.
Figure BDA0002080068760000101
Wherein, scoresIs the blending fraction of the article s, A1Is a preset shelf weight. Shelf parameter equal to Ms/α1Cs. Concurrence ofQuantity parameter equal to alpha1Cs. In general terms, the amount of the solvent to be used,
Figure BDA0002080068760000102
thus is provided with
Figure BDA0002080068760000103
Figure BDA0002080068760000104
In the above embodiment, the risk of contending for each source shelf on which an item is placed can be accurately assessed based on the number of shelves of the item and the amount of concurrency of the item.
In one embodiment of the invention, the blending score is a parameter determined by the number of shelves for the item, the amount of concurrency for the item, the number of recommended shelved items for the item, and the maximum number of shelves to place the item.
Specifically, the allocation score not only considers the number of shelves of the item related to the shelf portion and the amount of concurrency of the item, but also considers the stock condition of the item from the viewpoint of the item, thereby further determining the number of destination shelves that can be placed dispersedly.
Figure BDA0002080068760000111
On the basis of the formula (3), the number of recommended shelving items and the maximum item number are also considered
Figure BDA0002080068760000112
Wherein A is2Is a preset item weight.
Figure BDA0002080068760000113
Is an article parameter.
Figure BDA0002080068760000114
Is the maximum amount of inventory on the shelf of item s, i.e., the maximum number of items placed on the shelf. With maximum number of articles in the shelfThe maximum stock quantity and the maximum quantity of the recommended shelving items. As an example, A1＝10，A21. I.e., a deployment score from a shelf-robbery risk perspective that is determined to a greater extent relative to the inventory condition of the items.
Figure BDA0002080068760000115
The smaller the size of the tube is,
Figure BDA0002080068760000116
the larger the article parameter, the smaller the corresponding scoresThe smaller. It is indicated that the item s on the source shelf of the item s can be shelved on more destination shelves.
In the above embodiment, the allocation score of the goods is determined from the perspective of both the goods shelf robbery risk and the goods inventory condition, and the necessity of the goods warfare risk and the goods management of each source shelf is balanced.
The number of shelves of items placed on the source shelf cannot meet the picking requirements of the workstation, and then for each item there is a corresponding mix score. Multiple items may be placed on a source shelf, but only one item is dispensed at a time. In the case of multiple items to be allocated on an origin shelf, only the item with the minimum allocation score needs to be considered. Therefore, the source goods shelf can timely put down goods, and the risk of fighting for goods shelves is reduced.
S203, according to the sequence of the blending scores from low to high, putting the goods from the source goods shelf of the goods, and putting the goods on the destination goods shelf.
In one embodiment of the invention, the articles may be dispensed in order of decreasing dispense score, with continued reference to FIG. 4.
S402, sequencing the source shelves for placing the articles according to the sequence of the blending scores from low to high.
In one embodiment of the invention, the lower the deployment score, the greater the risk of a warfare. Thus, the source shelves on which the items are placed may be ordered in descending order of the mix score. The source shelf in the top rank order is allocated with the goods preferentially.
S403, putting down the goods from the goods shelf of the source of the goods, and putting the goods on the shelf of the destination.
To avoid the work station contending for the shelf, the source shelf needs to be dropped and then the dropped item is put on the destination shelf. The number of lower items s, i.e. the number of lower shelves, is related to the number of items placed on the source shelf. When the quantity of the articles placed on the source shelf is large, the quantity of the lower shelves is large; when the quantity of the articles placed on the source shelf is less, the quantity of the lower shelves is less.
Specifically, the items may be dispensed with different quantities of off shelves and quantities of on shelves based on a preset multiple of the quantity of recommended on shelves.
Referring to fig. 5, fig. 5 is a schematic flow chart of determining the number of pieces to be dispensed according to an embodiment of the present invention, which specifically includes:
s501, the number of the articles placed on the source shelf is larger than or equal to the preset multiple of the number of the recommended articles on the source shelf.
In the embodiment of the invention, the quantity of the articles on the lower shelf and the quantity of the articles on the upper shelf can be determined based on the relation between the quantity of the articles placed on the source shelf and the preset multiple of the quantity of the recommended articles on the upper shelf. Illustratively, the preset multiple may be equal to 2. The preset multiple can be preset according to the actual situation.
Twice as many articles are recommended to be put on shelf
