Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered 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.
Fig. 1 is a schematic diagram of a flow of a method for determining a warehouse entry item according to an embodiment of the present invention, as shown in fig. 1, the method includes:
Step 101: the number of turnover inventory boxes of a plurality of candidate articles is obtained.
The turnover inventory boxes are required to be maintained according to the sales tasks, the circulation links and the speed of the articles in order to complete the article circulation plan, ensure the normal supply of the market. The turnover inventory bin number may be the number of item inventory bins required for the alternate item cycle in a statistical cycle. In particular, the number of turnovers may be the quotient of the inventory of the candidate items required in a statistical cycle and the number of candidate items stored in each bin.
Step 102: and acquiring the association relation between the utilization rate of at least one carrying device and the number of the warehouse-out boxes.
The handling equipment is equipment for replacing manual operation of warehousing and ex-warehouse operation of articles, such as: elevator, conveyor equipment, etc. The number of bins is the sum of the number of bins in a specified statistical time. The utilization rate of the conveying equipment is the utilization rate of the conveying equipment in the statistical time. Generally, the utilization rate of the handling equipment is proportional to the number of bins, i.e., the greater the number of bins in a statistical time, the higher the utilization rate of the handling equipment. However, if the number of the outgoing boxes in the statistical time is too large, the task amount of the handling equipment may be too heavy, the use ratio of the handling equipment may not be changed, and the use ratio of the handling equipment may be reduced. Therefore, it is important to reasonably determine the number of the bins.
The association relationship between the utilization rate of the handling equipment and the number of the warehouse-out boxes can be determined according to a preset corresponding relationship. For example, the correspondence relationship between the number of outgoing boxes and the utilization rate of the handling equipment in the statistical time may be stored in the system. Specifically, the corresponding relationship may be that when the statistical time is one hour and the number of the warehouse-out boxes is 500, the utilization rate of the corresponding elevator is 5%, and the like. The association between the availability of the handling equipment and the number of bins can also be represented by a functional model comprising: a primary function model, a secondary function model, an exponential function model, or the like.
Step 103: the remaining utilization of the at least one handling device is determined.
In a warehouse, there may already be a variety of warehoused items, whose warehouse entry and exit would occupy the handling equipment resources. Thus, the handling equipment resources that these warehoused items will occupy are considered in determining other warehoused items. The remaining utilization rate can be the difference value obtained by subtracting the utilization rate of the carrying equipment occupied by the warehoused articles from the total utilization rate of the carrying equipment.
Step 104: and determining at least one warehouse-in article from the plurality of candidate articles according to the turnover inventory box numbers, the association relation and the residual utilization rate of the plurality of candidate articles.
At least one article which can be put in storage can be determined according to the turnover inventory box number and the association relation of a plurality of alternative articles under the residual utilization rate of the current handling equipment, so that the box number which can be put out in storage in a statistic period can be utilized more fully and reasonably for carrying out the put-out operation.
In the embodiment of the invention, the association relationship among the turnover inventory box number of a plurality of candidate articles, the utilization rate of at least one carrying device and the ex-warehouse box number and the residual utilization rate of at least one carrying device are comprehensively considered, and at least one storable article is determined from the plurality of candidate articles. Therefore, the method provided by the embodiment of the invention can solve the problem that the warehoused articles cannot be reasonably determined, and further the transportation equipment resources are reasonably utilized.
In one embodiment of the invention, a handling apparatus comprises: a hoist; before obtaining the association relationship between the utilization rate of at least one handling equipment and the number of the warehouse-out boxes, the method further comprises the following steps: acquiring the number of the warehouse-out boxes in a plurality of historical time periods and the utilization rate of the elevator in the plurality of historical time periods; and determining a first association relationship between the elevator utilization rate and the ex-warehouse box number according to the ex-warehouse box number in the plurality of statistical time periods and the elevator utilization rate in the plurality of statistical time periods.
The number of bins is the sum of the number of bins in a specified statistical time. The elevator utilization rate is the utilization rate in the statistical time. Generally, the utilization rate of the elevator is proportional to the number of the ex-warehouse boxes, that is, the more the number of the ex-warehouse boxes is in a statistical time, the higher the utilization rate of the elevator is. However, if the number of the warehouse-out boxes in the statistical practice is too large, the task amount of the elevator is possibly too heavy, the utilization rate of the elevator is unchanged, and the utilization rate of the elevator is possibly reduced instead.
The first association relationship between the utilization rate of the elevator and the number of the warehouse-out boxes can be determined according to a preset corresponding relationship. For example, the correspondence between the number of bins out and the elevator utilization rate within the statistical time may be saved in the system. Specifically, when the statistical time is one day and the number of the warehouse-out boxes is 5000, the corresponding elevator utilization rate is 2%, and the like. The association relationship between the elevator utilization rate and the number of the warehouse-out boxes can be expressed by a function model, wherein the function model comprises: a primary function model, a secondary function model, an exponential function model, or the like.
The explanation will be made by taking a linear function model as an example. Let x i and y i denote the number of bins per hour and elevator utilization per hour, respectively. From the historical data, the following regression equation is solved:
yi＝αe+βexi+εe
according to the least squares method, it is known that,
Wherein,Average of historical data representing number of bins out,/>Average of historical data representing elevator utilization. y=α e+βex+εe is the first association relationship between the elevator utilization rate and the number of bins.
In one embodiment of the invention, a handling apparatus comprises: the elevator, the incidence relation includes: a first association relation between the utilization rate of the elevator and the number of the warehouse-out boxes; determining a remaining utilization of at least one handling device, comprising: acquiring the number of turnover inventory boxes of each warehouse-in article and the upper limit utilization rate of a lifter; determining the occupied utilization rate of the elevator according to the turnover inventory box number of each warehouse-in article and the first association relation; and determining a first residual utilization rate of the hoisting machine according to the upper limit utilization rate of the hoisting machine and the occupied utilization rate of the hoisting machine.
The upper limit utilization rate of the hoisting machine can be set according to the number of hoisting machines, the warehouse scale and the like, and can also be set according to empirical tasks. And calculating the sum of the turnover inventory box numbers of the warehoused objects, and determining the occupied utilization rate of the elevator according to the obtained sum and the first association relation. And finally, subtracting the occupied utilization rate of the hoisting machine from the upper limit utilization rate of the hoisting machine, and determining the first residual utilization rate of the hoisting machine.
In one embodiment of the invention, a handling apparatus comprises: a shuttle; before obtaining the association relation between the utilization rate of at least one handling equipment and the number of the warehouse-out boxes, the method comprises the following steps: acquiring the number of the warehouse-out boxes in a plurality of historical time periods and the utilization rate of the shuttle in the plurality of historical time periods; and determining a second association relationship between the shuttle and the number of the delivery boxes according to the number of the delivery boxes in the plurality of statistical time periods and the shuttle utilization rate in the plurality of statistical time periods.
The number of bins is the sum of the number of bins in a specified statistical time. The shuttle utilization is the utilization within the statistical time. Generally, the utilization rate of the shuttle is proportional to the number of the delivery boxes, that is, the more the delivery boxes are in a statistical time, the higher the utilization rate of the shuttle is. However, if the number of the delivery boxes in the statistical reality is too large, the task amount of the shuttle is possibly too heavy, so that the utilization rate of the shuttle is unchanged, and the utilization rate of the shuttle is possibly reduced instead.
The second association relationship between the shuttle vehicle utilization rate and the number of the delivery boxes can be determined according to a preset corresponding relationship. For example, the correspondence between the number of bins and the shuttle availability may be maintained in the system over a statistical time. Specifically, when the statistical time is half an hour and the number of the delivery boxes is 300, the corresponding shuttle utilization rate is 3%, and the like. The association relationship between the shuttle utilization rate and the number of delivery boxes can also be represented by a functional model, wherein the functional model comprises: a primary function model, a secondary function model, an exponential function model, or the like.
The explanation will be made by taking a linear function model as an example. Let x i and z i denote the number of lockers per hour and the shuttle availability per hour, respectively. From the historical data, the following regression equation is solved:
zi＝αs+βsxi+εs
according to the least squares method, it is known that,
Wherein,Average of historical data representing number of bins out,/>Average of historical data representing shuttle utilization. z=α s+βsx+εs is the second association relationship between the shuttle utilization and the number of the delivery boxes.
In one embodiment of the invention, a handling apparatus comprises: shuttle, association includes: a second association relationship between the shuttle vehicle utilization rate and the number of delivery boxes; determining a remaining utilization rate of each handling device, comprising: acquiring the number of turnover inventory boxes of each warehouse-in article and the upper limit utilization rate of a shuttle; determining the occupied utilization rate of the shuttle according to the turnover inventory box number of each warehouse-in article and the second association relation; and determining a second residual utilization rate of the shuttle according to the upper limit utilization rate of the shuttle and the occupied utilization rate of the shuttle.
The upper limit utilization rate of the shuttle can be set according to the number of the shuttle, the warehouse scale and the like, and can also be set according to an empirical task. And calculating the sum of the turnover inventory box numbers of the warehoused objects, and determining the occupied utilization rate of the shuttle according to the obtained sum and the second association relation. And finally, subtracting the occupied utilization rate of the shuttle from the upper limit utilization rate of the shuttle, and determining the second residual utilization rate of the shuttle.
Fig. 2 is a schematic diagram of a flow of another method for determining articles to be put in storage according to an embodiment of the present invention, as shown in fig. 2, the method includes:
step 201: the number of turnover inventory boxes of a plurality of candidate articles is obtained.
Step 202: and acquiring a first association relation between the utilization rate of the elevator and the number of the warehouse-out boxes, and acquiring a second association relation between the utilization rate of the shuttle and the number of the warehouse-out boxes.
Step 203: and determining the first residual utilization rate of the hoisting machine and the second residual utilization rate of the shuttle.
Step 204: and determining at least one warehouse-in article from the plurality of candidate articles according to the turnover inventory box number, the first association relationship, the second association relationship, the first residual utilization rate and the second residual utilization rate of the plurality of candidate articles.
The turnover inventory box number, the first association relationship, the second association relationship, the first residual utilization rate and the second residual utilization rate of at least one warehouse-in article meet constraint conditions, and the constraint conditions comprise: the new utilization rate of the elevator aiming at least one warehouse-in article is not greater than the first residual utilization rate, and the new utilization rate of the elevator is obtained according to the turnover inventory box number of the warehouse-in article and the first association relation;
and/or, aiming at the at least one warehouse-in article, the new utilization rate of the shuttle is not more than the second residual utilization rate, and the new utilization rate of the shuttle is obtained according to the turnover inventory box number of the warehouse-in article and the second association relation.
The set remaining utilization rate of the elevator is b 1, and the remaining utilization rate of the shuttle is b 2. The residual utilization rate of the elevator is the utilization rate of the elevator which is remained and available after the elevator resources occupied by the warehouse-in and warehouse-out of the warehoused articles are removed. The shuttle vehicle residual utilization rate is the utilization rate of the shuttle vehicle residual utilization rate after the shuttle vehicle resources occupied by the warehouse-in articles for warehouse-out are removed.
Solving the following optimization model:
In the above formula, the set remaining utilization rate of the hoist is b 1, and a remaining utilization rate of the shuttle is b 2,,yi =1, which indicates that the selected candidate item sku i,yi =0 indicates that the selected candidate item sku i is not available.
In the constraint condition, the formula (1) indicates that the number of the newly added boxes corresponding to the newly added sku cannot exceed the remaining utilization rate of the elevator. (2) The formula indicates that the newly added number of boxes corresponding to the newly added sku cannot exceed the residual utilization rate of the shuttle. The utilization rate of the shuttle and the elevator can be regarded as two resources, and in the embodiment of the invention, the elevator resources and the shuttle resources are considered at the same time, so that the number of storage boxes is as large as possible, namely the utilization rate of the storage space is improved as much as possible under the condition that the upper use limit of the resources is not exceeded.
Fig. 3 is a schematic diagram of a flow of another method for determining articles to be put in storage according to an embodiment of the present invention, as shown in fig. 3, the method includes:
step 301: the number of turnover inventory boxes of a plurality of candidate articles is obtained.
Step 302: and acquiring a first association relation between the utilization rate of the elevator and the number of the warehouse-out boxes, and acquiring a second association relation between the utilization rate of the shuttle and the number of the warehouse-out boxes.

And/or, aiming at the at least one warehouse-in article, the new utilization rate of the shuttle is not more than the second residual utilization rate, and the new utilization rate of the shuttle is obtained according to the turnover inventory box number of the warehouse-in article and the second association relation;
And/or the sum of the turnover inventory bins of at least one storable article is not greater than the storable bin number.
Since the warehoused items are to be stored in the warehouse, the capacity of the warehouse is limited. Thus, in embodiments of the present invention, the remaining storage locations in the warehouse are considered in addition to the shuttle and elevator resources, such that the sum of the turnover inventory bins of the warehoused items is no greater than the warehoused bins.
The technical scheme aims to solve the problems that under the condition that resources (shuttle, hoister and storage place) of a shuttle (shuttle shelf) library remain, the method selects proper candidate articles sku (stock keeping unit ), can improve the utilization rate of production elements on the premise of ensuring that production tasks can be completed, and finally improves the space utilization rate of the shuttle library to the greatest extent. According to the technical scheme, the utilization rate of the shuttle and the elevator is considered, and the shuttle and the elevator cannot be used enough due to the increase of the delivery order quantity after the new sku is put in storage. Meanwhile, the put-in sku needs to be put in a warehouse integrally, namely, a part of the candidate articles cannot be put in a manual area, and the other part of the candidate articles are put in a warehouse in a share area, and if so, the later-stage delivery of the candidate articles is also carried out in a confluence mode. That is, the selected skus are all put into a shed library. Fig. 4 is a schematic diagram of a flow of a method for determining a warehouse entry item according to an embodiment of the present invention, and as shown in fig. 4, the method includes:
S01: and determining the number of the boxes required to be put in each sku in the storage of the alternative sku set which can be put in storage.
S02: determining a first association relation between the utilization rate of the elevator and the number of the warehouse-out boxes:

z＝αs+βsx+εs。
The specific deriving process of the second association relationship is detailed in the above embodiment of the present invention, and will not be described herein.
S04: assuming that n articles sku are stored in the alternative warehouse, the number of turnover inventory boxes corresponding to each sku is q 1,q2,…,qn, the set remaining utilization rate of the elevator is b 1, and the remaining utilization rate of the shuttle is b 2. The residual utilization rate of the elevator is the utilization rate of the elevator which is remained and available after the elevator resources occupied by the warehouse-in and warehouse-out of the warehoused articles are removed. The shuttle vehicle residual utilization rate is the utilization rate of the shuttle vehicle residual utilization rate after the shuttle vehicle resources occupied by the warehouse-in articles for warehouse-out are removed.

For example, the elevator utilization and shuttle utilization of the warehouse may be acquired for one week or one month, respectively. And respectively calculating an average value of the elevator utilization rate in a statistical time and an average value of the shuttle utilization rate in a statistical time, and taking the average values as an elevator utilization rate b e and a shuttle utilization rate b s occupied by the warehoused articles. After b e and b s are obtained, two split values f 1 and f 2, such as 75%, 80%, etc., are set. The remaining utilization rate of the elevator can be calculated to be b 1 and the remaining utilization rate of the shuttle to be b 2 through the following formula, wherein b emax is the upper limit utilization rate of the elevator, and b smax is the upper limit utilization rate of the shuttle.
b1＝bemax-be*f1
b2＝bsmax-bs*f2
Assuming that the upper limit of the remaining storable total bins of the storage system is b 3, the following optimization model is solved:
In the above formula, the set remaining utilization rate of the elevator is b 1, the remaining utilization rate of the shuttle is b 2, and the upper limit of the number of remaining storable total boxes of the storage system is b 3,yi =1, which indicates that the selected candidate item sku i,yi =0 indicates that the selected candidate item sku i is not available.
In the constraint condition, the formula (3) indicates that the number of the newly added boxes corresponding to the newly added sku cannot exceed the remaining utilization rate of the elevator. (4) The formula indicates that the newly added number of boxes corresponding to the newly added sku cannot exceed the residual utilization rate of the shuttle. (5) The formula indicates that the newly added bin number corresponding to the newly added sku cannot exceed the upper limit of the number of remaining storable bins in the storage system. The utilization rate of the shuttle and the hoister and the residual empty storage position can be regarded as three resources, and under the condition that the use upper limit of the three resources is not exceeded, the algorithm model enables the number of storage boxes to be as large as possible, namely the storage space utilization rate is improved as much as possible.
