Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The method for optimizing the warehousing of commodities in the commodity warehousing is based on the warehousing system shown in the attached figure 1, the warehousing system comprises a storage area 1 and a working area 2, commodities are transferred between the storage area 1 and the working area 2 through a carrying system 3, and the carrying system 3 at least comprises a carrying AGV 31. A shelf 11 is provided in the storage area 1, and a picking station 21 is provided in the working area 2. The warehousing system also comprises a control center which can carry out operations such as dispatching the operation of the carrying system 3, dispatching sorting tasks to the picking workstations 21 of the working area 2, arranging goods positions for goods to be warehoused and the like.
The shelf 11 may be in the form of a mobile shelf or a fixed shelf, and the shelf 11 has a storage space for storing goods. If the rack 11 is in the form of a moving rack, the carrying AGV31 is an AGV that can carry or move the rack, the carrying AGV31 carries the rack 11 to the picking station 21 for sorting by the picking machine or personnel at the picking station. If rack 11 is in the form of a fixed rack, each bay of rack 11 is provided with bins that store at least one item of merchandise, and carrying AGV31 is a bin robot that can remove bins from and return bins to the bay, and carrying system 3 can carry bins to picking station 21 for sorting by the picking station's staff or picking machine.
In the present embodiment, the shelf 11 is described as a fixed shelf.
Preferably, the carrier system 3 further comprises an annular conveyor line 32, said annular conveyor line 32 being interposed between said storage area 1 and said sorting area 2. One side of annular transfer chain 32 that is close to storage area 1 is provided with AGV butt joint line 33, and the quantity of AGV butt joint line 33 equals with the quantity of goods shelves 11, and the workbin is put to annular transfer chain 32 to transport AGV31 accessible AGV butt joint line 33, also can accept the workbin that gets off from annular transfer chain 32 from the tip of AGV butt joint line 33. One side of annular transfer chain 32 towards workspace 2 is provided with workstation butt joint line 34, and workstation butt joint line 34 can carry the workbin on the annular transfer chain 32 to selecting workstation 21 and sort, can also carry the workbin after selecting workstation 21 and sort back annular transfer chain 32.
Because the goods positions on the goods shelf 11 are different from the working area 2 in distance, the round-trip time between the material box of each goods position and the working area 2 is different, the round-trip time of the material box of the goods position close to the working area 2 is short, the sorting efficiency of the corresponding goods is high, the round-trip time of the material box of the goods position far from the working area 2 is long, and the sorting efficiency of the corresponding goods is low. Therefore, the concept of the heat degree of the goods position is introduced into the application to distinguish the goods position, the heat degree of the goods position close to the working area 2 is high, and the heat degree of the goods position far away from the working area 2 is low. In the warehouse system shown in FIG. 1, the slots on shelves 11 are arranged in vertical rows, with 7 lanes between shelves 11 for carrying AGV31, and each vertical row has a linear array of 16 slots. In the embodiment, the goods positions on the goods shelf 11 are divided into a plurality of parts, each part of the goods positions corresponds to one kind of the goods position heat degree, in the embodiment, the goods positions in each vertical row are divided into 16 equal parts, 16 goods positions are respectively endowed with 16 goods position heat degrees of 1-16 grades according to the distance from the goods positions to the working area 2, for the whole storage area 1, the goods position heat degrees of all the goods positions in the 1 st horizontal row are 16, the goods position heat degrees of all the goods positions in the 2 nd horizontal row are 15, and so on, the goods position heat degrees of all the goods positions in the 16 th horizontal row are 1. In other embodiments, the grading of the cargo space may also be scaled.
Based on the warehousing system, as shown in fig. 2, the method for optimizing warehousing commodities in commodity warehousing according to the present invention includes the following steps S101-S104 (the main implementation body of the method for optimizing warehousing commodities in commodity warehousing is a control center, the step numbers involved in the present invention are not used to limit the execution sequence of the steps, the step numbers represent a preferred execution sequence, and the execution sequence of some steps can be exchanged or synchronously executed as required):
step S101, acquiring commodity heat of commodities to be warehoused;
the commodity popularity is an index for evaluating the popularity degree of the commodity, and the popularity of the commodity is higher when more orders related to the relevant commodity are provided or the commodity delivery amount is larger; the fewer orders related to the associated goods or the smaller the shipment volume of the goods, the less hot the goods are. The grade number of the commodity heat is equal to that of the goods yard heat, namely the goods yard heat has 16 grades in the embodiment, and the grade number of the commodity heat is also 16 grades which are respectively 1, 2 and 3 … … 16.
Step S102, calculating the target spreading degree of the commodities to be warehoused;
the target spreading degree is related to the heat degree, the higher the heat degree of the commodity is, the more hot the commodity is, the higher the possibility that a plurality of picking workstations need to dispatch the commodity during sorting is, therefore, the storage of a plurality of goods positions for the commodity with high heat degree is needed to meet the requirement of the simultaneous dispatching of the plurality of picking workstations, namely, the higher the target spreading degree is, otherwise, if the heat degree of the commodity is low, and only occasionally an order relates to the commodity, the situation that the plurality of picking workstations need the commodity is basically impossible to occur, the commodity only needs to be stored in one goods position, and the target spreading degree of the commodity is also lower.
Step S103, selecting a plurality of alternative goods positions for the goods to be warehoused according to the goods heat;
in this step, when the candidate goods space is selected for the goods to be warehoused, the goods space heat degree of the selected candidate goods space is matched with (not necessarily equal to) the goods heat degree of the goods to be warehoused.
And S104, selecting one alternative goods space as a target goods space of the goods to be warehoused so as to enable the actual spreading degree of the goods to be warehoused to be closest to the target spreading degree.
In this step, if the target spreading degree of the goods to be warehoused is 2 and a goods space is already stored in the first vertical row of the current warehousing area, the selected two alternative goods spaces are respectively located in the first vertical row and the second vertical row and located in the same horizontal row, and then the alternative goods space in the second vertical row is selected as the target goods space.
Preferably, the acquiring the commodity heat of the commodity to be warehoused in the step S101 specifically includes the following steps S201 to S204:
step S201, calculating the heat value of the goods to be warehoused according to the unfinished orders and/or finished orders;
step S202, sorting all the commodities to be warehoused according to the heat value;
step S203, dividing all the sorted commodities to be warehoused into a first set group number;
in this step, the number of the first set group is equal to the grade number of the heat degree of the cargo space, i.e. 16 groups are obtained.
And step S204, endowing different commodity heat degrees for different groups of commodities to be warehoused, wherein the commodity heat degrees of the commodities to be warehoused in the same group are the same.
In this step, corresponding to this embodiment, the commodity heat of 16 gears, 1 to 16, is respectively assigned to each group of commodities to be warehoused. If multiple commodities are stored in the same bin, the commodity heat of all the commodities in the bin is equal to the commodity heat of the commodity with the highest commodity heat in the bin.
In addition to the above method, the commodity heat of the commodity to be warehoused can be obtained in other manners, such as the ready-made heat value referring to other databases.

step S303, counting the number C of completed orders containing the commodities to be warehoused in a set time period; the preset coefficient corresponding to the parameter is j;
step S304, counting the total delivery quantity D of the commodities to be warehoused within a set time period; the preset coefficient corresponding to the parameter is k;
and step S305, calculating the heat value of the commodity to be warehoused according to the formula H = H A + i B + j C + k D.
Through the mode, the unfinished orders and the finished orders are fully considered to obtain the heat value of the commodity to be warehoused, two dimensions of the order quantity and the shipment quantity are considered corresponding to each type of orders, and the obtained heat value can fully reflect the heat condition of the commodity to be warehoused.
Preferably, the step S102 of calculating the target spreading degree of the goods to be warehoused includes the following steps S401 to S402:
s401, sorting all the commodities to be warehoused according to the heat value of the commodities to be warehoused;
step S402, dividing all the sorted commodities to be warehoused into a second set group number, and determining a specific numerical value of the scattering degree for each group of commodities to be warehoused as the target scattering degree of all the commodities to be warehoused in the corresponding group.
In this step, corresponding to this embodiment, the maximum value of the target spreading degree and the second set group number are both equal to the number of the lanes in the storage area 1, so as to ensure that the corresponding cargo space beside each lane can be shipped for a certain commodity with high heat degree under extreme conditions, because there are 7 lanes in the storage area 1 in the storage system shown in fig. 1, the maximum value of the target spreading degree is set to 7, the minimum value of the target spreading degree is set to 1, the value of the target spreading degree is 7, and the value of the second set group number is also set to 7. The method for grouping the commodities to be put in storage can be an equal division method, and can also be grouped according to a set proportion.
Preferably, in the step S103, before selecting a plurality of candidate goods spaces for the goods to be warehoused according to the goods heat, the method further includes the following step S501:
s501, setting the hot degree of each goods position;
in this step, the goods location heat is allocated to each goods location according to the location of each goods location, and the manner of setting the goods location heat has been described above, and will not be described herein again.
Based on this, the selecting a plurality of candidate goods spaces for the goods to be warehoused according to the goods heat degree in the step S103 specifically includes the following steps S601-S603:
step S601, judging whether all goods positions corresponding to the target goods position heat degree have idle goods positions, if so, entering step S602, otherwise, entering step S603; the target goods space heat degree is equal to the commodity heat degree of the current commodity to be warehoused;
step S602, using the goods positions (the idle goods positions corresponding to the target goods position heat) as alternative goods positions;
step S603, searching for an idle goods position in the goods positions corresponding to the goods position heat degrees adjacent to the target goods position heat degree as an alternative goods position.
In the step, if the target goods position heat degree is h and the goods positions corresponding to the goods position heat degree h are not idle, the goods positions with the goods position heat degrees of h +1 and h-1 are checked, and if one or more idle goods positions can be found, the next step of calculation is carried out; otherwise, if not, the recursive calculation is continued, and the goods positions with the goods position heat degrees of h +2 and h-2 are checked, and so on until the free goods position is found. In the recursive checking process, when the goods space heat h is increased or decreased, if the change result exceeds a reasonable numerical range (such as 1-16), the change result is discarded.
Further, the selecting one of the candidate cargo spaces in the step S104 as the target cargo space of the goods to be warehoused so that the actual spreading degree of the goods to be warehoused is closest to the target spreading degree specifically includes the following steps S701-S703:
step S701, judging whether the number of the spare goods spaces is 1, if so, entering step S702, otherwise, entering step S703;
step S702, using the only alternative goods position as the target goods position;
