specific Embodiment

[0113] Coding settings: When initializing the population, the location allocation coordinates are randomly generated. Firstly, the goods to be put into storage are coded, and the codes correspond to the turnover rate, quality and other information; secondly, the location of the goods is coded, and the length of the code is determined by the quantity of goods to be put into the warehouse, and the codes are divided into several segments, each representing a cargo The coordinates of the position, because the coordinates of the position are (x, y, z) three-dimensional existence, so define the row, column and row to be represented by three numbers of x, y, z respectively, that is, the length of the position code N=3N α .

[0114] Set the relevant parameters of shelves and stackers: there are a total of c rows of shelves, each row of shelves has a row and b layer, the length of the shelf is l, and the high position of the shelf is h; it is the number of each shelf in the group of sh...

Abstract

The invention discloses a goods allocation distribution model establishment method in bidirectional layout mode, and the method enables each piece of goods to be reasonably allocated to a storable goods allocation according to the goods warehouse-out / warehouse-in frequency, the center of gravity of a goods shelf and the goods aggregation degree as evaluation standards, thereby achieving the purposes that the operation time of a stacking machine for executing a warehouse-in task is short, the overall center of gravity of the goods shelf is low, and the associated cargo are placed in an approaching mode. Meanwhile, in a follow-up optimization algorithm, an improved shuffled frog leaping algorithm is provided to carry out simulation optimization on the model, meanwhile, when the algorithm is adopted, a new local updating strategy is designed, a self-adaptive dynamic synchronization factor is introduced, and good performance is achieved in any stage of optimization solution. The automatic selection of the stocker to the warehouse-out / warehouse-in platform is realized, and the actual working condition requirement of'two-way type 'can be met.

Description

technical field [0001] The invention belongs to the category of establishing a cargo space allocation scheduling model in the field of automatic three-dimensional warehouse scheduling, and in particular relates to a method for establishing a cargo space allocation scheduling model in a two-way layout mode. Background technique [0002] Storage space allocation refers to placing goods in suitable storage spaces according to actual production needs, which is a key issue affecting the storage efficiency and structural stability of large-scale industrial three-dimensional warehouses. In production logistics, large-scale industrial three-dimensional warehouses mostly adopt a centralized storage / retrieval management method, with long and deep lanes and a single exit / entry port. In order to shorten the distance between the out / in warehouse and the storage point deep in the shelf, and improve the storage efficiency of large-scale industrial three-dimensional warehouses, some enterpr...
