Step S3 includes:
s31, evaluating the compliance of the operation result to obtain a compliance evaluation result, and judging whether the compliance evaluation result meets the preset compliance requirement or not;
in this example, the variable W for Compliance (Compliance)cThe method comprises the following steps:
the stock of the warehouse meets the quantity requirement of the Order or the residual capacity of the warehouse meets the quantity requirement of the Order, namely the quantity of the Order Goods (Order _ Goods _ Num/N)og) By the variable NogRepresents, satisfies the number requirement Nog1, otherwise NogSince this compliance index is absolute priority, there are only two outcomes, not weighted;

In this embodiment, after the regularity is judged, the strategy performance is evaluated. Evaluation efficacy was compared from the evaluation group and the intelligent group of the present invention. The data of the evaluation group can be set, and can also be data obtained when workers in the warehouse carry out the racking operation. The performance of the invention is the result obtained by executing the operation of the upper and lower shelves according to the result obtained by the operation. The performance indexes evaluated are space full utilization and time cost, and specifically are as follows:
the space full utilization: the number of non-integer channels (an index for describing whether the library bit is fully utilized), the dispersion of the library bit (an index for describing a space dispersion state), and the number of integer channels (an index for describing whether the library bit is fully utilized).
In this embodiment, when the goods a occupies the whole channel of the storage space, the channel is called as the "whole channel" of the goods a; when the goods A do not occupy the whole channel of the stock position, the channel is called as a non-whole channel of the goods A. In a designated warehouse, the number of all the 'whole channels' of the A goods is recorded as the number of the whole channels of the A goods and is recorded as X1And the number of all the non-whole channels of the goods A is recorded as the number of the non-whole channels of the goods A and is recorded as Y1. Then the loss function for the integer and non-integer channels is calculated as:
the larger the value of the loss function is, the more the number of the non-integral channels is, the less the library bit is fully utilized, otherwise, the full library bit is fully utilized.
Referring to fig. 3 and 4, white represents empty storage locations, and black represents storage locations where goods are stored. In fig. 3, three white empty bin bits in succession are counted as only one bin bit in the relative bin bit dispersion, and the relative dispersion is 1, but in the absolute bin bit dispersion, the absolute dispersion of any one bin bit is 1, that is, the absolute dispersion empty bin bit is 3. In fig. 4, three white empty bin bits are separated, and are absolute discrete empty bin bits, i.e. 3 empty bin bits are counted.
Relative library position dispersion: as shown in fig. 3, if there are a plurality of empty bin bits or non-empty bin bits arranged together in succession, these successive bin bits are regarded as a relative bin bit with a dispersion of 1.
Absolute bin spread: as shown in fig. 3 and 4, the absolute dispersion of any one bin bit is 1.
In both warehouse-out and warehouse-in, the warehouse location dispersion is considered. The higher the dispersion of the warehouse location, the more discontinuous the discharge of the goods in the warehouse is, and the goods are not convenient to take and put.
Warehouse bit dispersion (Warehouse _ Location _ Dispersion _ Degreee/D)wld) The overall degree of dispersion of all the positions in the warehouse.
Relative dispersion of library bits (Location _ Relative _ Dispersion _ Degreee/D)lrd) The continuous empty storage positions or the storage positions for placing goods are regarded as one storage position, and the relative dispersion of a continuous storage position group is 1.
Location _ absolute _ Dispersion _ Degreee/Dlad) That is, the absolute dispersion of any bin bit is 1 regardless of the discontinuity.
When D is presentwld<D, the dispersion of the library bit satisfiesIf not, the efficiency is not satisfied. Wherein D is a preset library bit dispersion threshold value.
Time cost: the time required for the cargo operation, an index describing the cost of time, is the sum of the time spent in each bay.
In this embodiment, knowing the height h of the warehouse where the goods is located, the actual horizontal moving distance x from the warehouse to the designated door, the working efficiency y of workers (the higher the efficiency, the larger y), the current number of operations of the warehouse (the larger the number of operations, the larger z, the larger the number of operations may affect the operation event), the accessibility c of the goods (the easier the goods are taken, the lower the value of c is), and the time T when the forklift is jammed due to congestion of the warehouse, the completion time T for operating one warehouse may be the following formula:
T＝w1*h+w2*x+w3*(1-y)+w4*z+w5*c+w6*t
wherein, w1、w2、w3、w4、w5、w6Are the corresponding weights.
And after the summation of the time of all the warehouse positions needing to be operated for a certain type of goods, obtaining the operation time of the certain goods.
Step S4 includes:
s41, evaluating the strategy efficiency of the operation result to obtain an efficiency evaluation result, and judging whether the efficiency evaluation result meets the preset efficiency requirement;
s42, if the performance evaluation result does not satisfy the preset performance requirement, go to step S5.
And S43, if the performance evaluation result meets the preset performance requirement, namely the compliance evaluation result also meets the preset compliance requirement, repeating the steps S2-S5, and continuously optimizing the algorithm.
In this embodiment, the evaluation of the operation result may be performed after the operation result is obtained and the racking operation is performed each time, or a period may be set, and the evaluation may be performed periodically after the operation result is obtained and the racking operation is performed each time in the period.
S5, the operation module generating the operation result according to the order data is optimized, and the flow returns to the step S21.
In this embodiment, for the operation result that does not satisfy the preset compliance requirement and the preset performance requirement, the algorithm is optimized according to the evaluation result.
