Embodiment Construction
[0080] The present invention will be further described below in conjunction with the accompanying drawings.
[0081] refer to Figure 1 to Figure 9 , a storage space allocation method for a cold storage-oriented mobile shelf storage system, comprising the following steps:
[0082] Step 1. Establish a multi-objective location allocation optimization model with the goal of improving picking efficiency, shelf stability, and item correlation in the same picking lane;
[0083] Calculate the objective function f to improve the picking efficiency 1 ,
[0084] First calculate the movement of the access trolley from the I / O position to the location (x, y, z), assuming that the shelf needs to be moved, the running time in the horizontal direction is:
[0085]
[0086] Among them, y represents the coordinates of the cargo location (x, y, z) along the y direction, w represents the width of the cargo cell, and v y Indicates the speed of the access car along the y direction; t r Ind...

A storage location allocation method for mobile shelf storage systems for cold storage, which allocates highly correlated items to the same picking lane, reduces the possibility of opening the picking lane multiple times, and uses the similarity coefficient of the order items as a measure of the correlation Based on the basis, and comprehensively considering the item picking frequency and the center of gravity of the shelf, a multi-objective cargo location allocation optimization model is established, and then the improved invasive weed algorithm is used to solve the optimal storage location of the goods, and a part of the initial population is generated by using the greedy algorithm, and then a reasonable setting is made. The spatial diffusion operator, and finally introduce the evolutionary reversal operation of the genetic algorithm. The invention has strong global search ability and local search ability, remarkable optimization effect, and effectively improves warehouse picking efficiency and shelf stability.
Description
technical field [0001] The invention belongs to the field of storage management, and in particular relates to a method for allocating goods positions of a mobile shelf storage system facing cold storage. Background technique [0002] In recent years, with the rapid development of the cold chain logistics industry, cold storage has attracted more and more attention from logistics companies. Warehouse energy consumption, investment cost and efficiency issues have always been pain points in cold storage. Therefore, choosing a storage system with compact access space and timely service time has become a new direction for the development of cold storage. As a new compact storage system, the mobile shelf storage system only needs to set aside a picking lane for the storage and retrieval trolley to operate, and distribute the lanes through the movement of the shelves, and then the storage and withdrawal trolley enters the lane to complete the goods in and out of the warehouse. The...
