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.
Fig. 1 is a schematic diagram of a flow of a method for determining an item to be put in storage according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step 101: a number of turnaround inventory bins for a plurality of alternative items is obtained.
The turnover inventory storage number is the number of article inventory storage required by an enterprise to complete an article circulation plan and ensure normal supply of the market, and a certain quantity of turnover is kept according to an article sales task, an article circulation link and the speed. The turnover inventory storage number can be the number of the article inventory storage required by the period of the alternative articles in a statistical period. In particular, the number of turnaround inventory bins may be the quotient of the inventory of alternative items required over a statistical period and the number of alternative items stored in each bin.
Step 102: and acquiring the incidence relation between the utilization rate of at least one carrying device and the number of the ex-warehouse boxes.
The handling equipment replaces manual work to realize the equipment of warehouse entry and warehouse exit operation of article, if: a lifter, a conveyor, conveying equipment and the like. The number of ex-warehouse boxes is the sum of the number of ex-warehouse boxes in a specified statistical time. The utilization rate of the transport equipment is the utilization rate of the transport equipment within the statistical time. Generally, the utilization rate of the transporting equipment is proportional to the number of the delivery boxes, i.e. the more the delivery boxes are in a statistical time, the higher the utilization rate of the transporting equipment is. However, if the number of outgoing boxes within the statistical time is too large, the workload of the transport facility may be too heavy, the utilization rate of the transport facility may not be changed, and the utilization rate of the transport facility may be decreased. Therefore, it is important to reasonably determine the number of delivery boxes.
The incidence relation between the utilization rate of the handling equipment and the number of the delivery boxes can be determined according to a preset corresponding relation. For example, the system may store a correspondence between the number of outgoing boxes and the utilization rate of the transport facility within a statistical time. Specifically, the corresponding relationship may be that when the statistical time is one hour, the number of ex-warehouse boxes is 500, the utilization rate of the corresponding hoisting machine is 5%, and the like. The relationship between the utilization rate of the handling equipment and the number of the delivery boxes can be further represented by a functional model, and the functional model comprises: a first order function model, a second order function model, an exponential function model, or the like.
Step 103: a remaining utilization of the at least one handling apparatus is determined.
In the warehouse, there may be a plurality of warehoused articles, and the warehousing-in and warehousing-out of the warehoused articles will occupy the resources of the handling equipment. Therefore, when determining other warehouseable items, the transportation equipment resources occupied by the warehouseable items are considered. The residual utilization rate may be a difference obtained by subtracting the utilization rate of the transport apparatus occupied by the warehoused articles from the total utilization rate of the transport apparatus.
Step 104: and determining at least one warehousing-capable article from the plurality of candidate articles according to the turnover warehousing-storage box number, the incidence relation and the residual utilization rate of the plurality of candidate articles.
Under the residual utilization rate of the current carrying equipment, at least one article capable of being warehoused can be determined according to the turnover warehousing box number and the incidence relation of a plurality of candidate articles, so that the box number of the articles discharged from the warehouse in a statistical period can be fully and reasonably used for discharging operation.
In the embodiment of the invention, the number of turnover inventory boxes of a plurality of candidate articles, the incidence relation between the utilization rate of at least one conveying device and the number of delivery boxes and the residual utilization rate of at least one conveying device are comprehensively considered, and at least one warehousing-capable 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 warehousing-capable articles cannot be reasonably determined, and further the resources of the conveying equipment are reasonably utilized.
In one embodiment of the invention, a handling apparatus comprises: a hoist; before obtaining the incidence relation between the utilization rate of at least one handling device and the number of the ex-warehouse boxes, the method further comprises the following steps: acquiring the number of ex-warehouse boxes in a plurality of historical time periods and the utilization rate of the hoisting machine in the plurality of historical time periods; and determining a first incidence relation between the utilization rate of the hoisting machine and the number of the ex-warehouse boxes according to the number of the ex-warehouse boxes in the plurality of statistical time periods and the utilization rate of the hoisting machine in the plurality of statistical time periods.
The number of ex-warehouse boxes is the sum of the number of ex-warehouse boxes in a specified statistical time. The elevator utilization is the utilization within the statistical time. Generally, the utilization rate of the elevator is proportional to the number of the delivery boxes, i.e., the more the delivery boxes are in a statistical time, the higher the utilization rate of the elevator is. However, if the number of the ex-warehouse boxes in the actual statistics is too large, the workload of the hoisting machine is too heavy, the utilization rate of the hoisting machine is not changed, and the utilization rate of the hoisting machine is reduced.
The first incidence relation between the utilization rate of the hoister and the number of the ex-warehouse boxes can be determined according to the preset corresponding relation. For example, the system may store a correspondence between the number of ex-warehouse bins in the statistical time and the utilization rate of the elevator. Specifically, if the statistical time is one day and the number of the ex-warehouse boxes is 5000, the utilization rate of the corresponding elevator is 2%, and the like. The incidence relation between the utilization rate of the elevator and the number of the ex-warehouse boxes can be further represented by a function model, and the function model comprises the following components: a first order function model, a second order function model, an exponential function model, or the like.
The following explanation is given by taking a linear function model as an example. Let xiAnd yiThe number of bins taken out of the warehouse per hour and the utilization rate of the elevator per hour are respectively expressed. From the historical data, the following regression equation was solved:
yi＝αe+βexi+εe
according to the least square method, it can be known that,
wherein the content of the first and second substances,
the average of the historical data representing the number of ex-warehouse bins,
an average of historical data representing elevator utilization. y alphae+βexεeNamely a first incidence relation between the utilization rate of the hoister and the number of the ex-warehouse boxes.
In one embodiment of the invention, a handling apparatus comprises: the elevator, the incidence relation includes: a first incidence relation between the utilization rate of the hoister and the number of the ex-warehouse boxes; determining a remaining utilization of at least one handling apparatus, comprising: acquiring the turnover warehousing storage number of each warehoused article and the upper limit utilization rate of a hoist; determining the occupied utilization rate of the elevator according to the turnover storage box number of each warehoused article and the first incidence relation; and determining the first residual utilization rate of the elevator according to the upper limit utilization rate of the elevator and the occupied utilization rate of the elevator.

And calculating the sum of the turnover storage box number of each warehousing article, 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 hoister from the upper limit utilization rate of the hoister to determine the first residual utilization rate of the hoister.
In one embodiment of the invention, a handling apparatus comprises: a shuttle vehicle; before obtaining the incidence relation between the utilization rate of at least one carrying device and the number of the ex-warehouse boxes, the method comprises the following steps: acquiring the number of ex-warehouse boxes in a plurality of historical time periods and the utilization rate of shuttle vehicles in the plurality of historical time periods; and determining a second incidence relation between the shuttle cars and the number of the ex-warehouse boxes according to the number of the ex-warehouse boxes in the plurality of statistical time periods and the utilization rate of the shuttle cars in the plurality of statistical time periods.
The number of ex-warehouse boxes is the sum of the number of ex-warehouse boxes in a specified statistical time. The shuttle utilization rate is the utilization rate within the statistical time. Generally, the utilization rate of the shuttle cars is in direct proportion to the number of the delivery boxes, namely, the more the delivery boxes are in a statistical time, the higher the utilization rate of the shuttle cars is. However, if the number of the ex-warehouse boxes in the actual statistics is too large, the task amount of the shuttle cars is possibly too heavy, the utilization rate of the shuttle cars is not changed, and the utilization rate of the shuttle cars is also possibly reduced.
The second incidence relation between the utilization rate of the shuttle cars and the number of the ex-warehouse boxes can be determined according to the preset corresponding relation. For example, the correspondence between the number of ex-warehouse boxes and the utilization rate of the shuttle cars within the statistical time can be saved in the system. Specifically, if the counting time is half an hour and the number of the delivery boxes is 300, the utilization rate of the corresponding shuttle cars is 3%, and the like. The incidence relation between the shuttle utilization rate and the number of the ex-warehouse boxes can also be represented by a function model, and the function model comprises the following components: a first order function model, a second order function model, an exponential function model, or the like.
The following explanation is given by taking a linear function model as an example. Let xiAnd ziThe number of ex-warehouse boxes per hour and the shuttle utilization rate per hour are respectively represented. From the historical data, the following regression equation was solved:
zi＝αs+βsxi+εs
according to the least square method, it can be known that,
wherein the content of the first and second substances,
the average of the historical data representing the number of ex-warehouse bins,
an average of historical data representing shuttle utilization. z ═ alphas+βsx+εsNamely a second incidence relation between the utilization rate of the shuttle cars and the number of the ex-warehouse boxes.
In one embodiment of the invention, a handling apparatus comprises: the shuttle car, the incidence relation includes: a second incidence relation between the utilization rate of the shuttle cars and the number of the ex-warehouse boxes; determining the residual utilization rate of each handling device, comprising: acquiring the turnover storage box number of each warehoused article and the upper limit utilization rate of the shuttle car; determining the occupied utilization rate of the shuttle car according to the turnover storage box number of each warehoused article and the second incidence 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.

And calculating the sum of the turnover storage box number of each warehousing article, and determining the occupied utilization rate of the shuttle car according to the obtained sum and the second association relation. And finally, subtracting the occupied utilization rate of the shuttle vehicle from the upper limit utilization rate of the shuttle vehicle to determine a second residual utilization rate of the shuttle vehicle.

and/or aiming at least one shuttle vehicle newly increased utilization rate of the warehousing-capable articles, wherein the newly increased utilization rate of the shuttle vehicle is not more than the second residual utilization rate and is obtained according to the turnover warehousing-capable article storage box number and the second incidence relation.
The residual utilization rate of the elevator is set as b1The residual utilization rate of the shuttle car is b2. The residual utilization rate of the elevator is the residual available utilization rate of the elevator after elevator resources occupied by the warehoused articles discharged from the warehouse are eliminated. The residual utilization rate of the shuttle car is the utilization rate of the shuttle car which is still available after the shuttle car resources occupied by the warehoused goods are removed.
The following optimization model was solved:

According to the technical scheme, the utilization rate of the shuttle car and the elevator is considered, and the shuttle car and the elevator cannot be insufficient due to the increase of the warehouse-out single amount after the new sku is warehoused. Meanwhile, the sku to be put in storage needs to be put in storage integrally, namely, part of the alternative articles cannot be put in a manual area and part of the alternative articles can be put in a shutdown area, and if so, the alternative articles need to be combined when going out of the storage in the later period. That is, all the selected skus are required to be put into the shuttle library. Fig. 4 is a schematic diagram of a flow of a further method for determining an item to be put in storage according to an embodiment of the present invention, as shown in fig. 4, the method includes:
s01: and determining a set of alternative skus which can be put in storage and the number of boxes which need to be put in storage for each sku.
S02: determining a first incidence relation between the utilization rate of the elevator and the number of the ex-warehouse boxes:
y＝α\+βex+εe。
the details of the specific derivation process of the first association relationship are described in the above embodiments of the present invention, and are not described herein again.
S03: determining a second incidence relation between the utilization rate of the shuttle cars and the number of the ex-warehouse boxes:
z＝αs+βsx+εs。
the detailed derivation process of the second association relationship is described in the above embodiments of the present invention, and is not described herein again.
S04: supposing that n kinds of optional articles sku stored in a warehouse are provided, the number of turnover stock boxes corresponding to each sku is q1，q2，...，qnThe residual utilization rate of the elevator is set as b1The residual utilization rate of the shuttle car is b2. The residual utilization rate of the elevator is the residual available utilization rate of the elevator after elevator resources occupied by the warehoused articles discharged from the warehouse are eliminated. The residual utilization rate of the shuttle car is the utilization rate of the shuttle car which is still available after the shuttle car resources occupied by the warehoused goods are removed.
Utilization rate b of elevator occupied by warehoused articleseAnd the utilization rate b of the shuttle car occupied by the warehoused goodssCan be calculated using historical data. For example, elevator utilization and shuttle utilization may be obtained for a week or month of the warehouse, respectively. Respectively calculating the average value of the utilization rate of the hoister in the statistical time every day and the average value of the utilization rate of the shuttle cars in the statistical time every day, and taking the average values as the utilization rate b of the hoister occupied by the warehoused goodseAnd shuttle utilization bs. Respectively calculate beAnd bsThen, two fractional values f are set1And f2Such as 75%, 80%, etc. The residual utilization rate of the elevator can be calculated as b through the following formula1The residual utilization rate of the shuttle car is b2Wherein b isemaxTo the upper limit utilization of the elevator, bsmaxThe upper limit utilization rate of the shuttle car is obtained.
b1＝bemax-be*f1
b2＝bsmax-bs*f2
Assuming that the upper limit of the remaining total storable boxes of the storage system is b3Solving the following optimization model:
yi∈{0，1}
in the above formula, the set residual utilization rate of the elevator is b1The residual utilization rate of the shuttle car is b2The upper limit of the remaining storable total number of boxes of the storage system is b3，yi1 denotes the selected alternative item skui，yi0 means that no alternative item sku is selectedi。
In the constraint conditions, the formula (3) shows that the number of newly added bins corresponding to the newly added sku cannot exceed the residual utilization rate of the elevator. (4) And the formula shows that the number of newly added boxes corresponding to the newly added sku cannot exceed the residual utilization rate of the shuttle car. (5) The formula shows that the number of newly added boxes corresponding to the newly added sku cannot exceed the upper limit of the number of the remaining storable boxes in the storage system. The utilization rate of the shuttle car and the hoister and the residual empty storage positions 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 the storage boxes to be as large as possible, namely the utilization rate of the storage space is improved as much as possible.
S05: select yiAnd warehousing the sku corresponding to 1.
The technical scheme of the embodiment of the invention adopts a two-stage method. In the first stage, the functional relation between the utilization rates of the ex-warehouse bin, the shuttle car and the hoister is determined by means of linear regression analysis through historical data. The first stage is necessary preparation of the second stage, and after the functional relation is determined, the utilization rate of the shuttle car and the hoister can be increased by one bin when the bin is taken out of the warehouse. And in the second stage, the optimal alternative item sku is found out by solving the operation optimization model. The objective function means to select those alternative items sku that can be stored in as many cases as possible.
