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...

Abstract

The invention discloses a goods location distributing method of a mobile shelf warehousing system for a refrigeration house. The goods location distributing method includes the steps: distributing items with strong correlation to the same sorting roadway, thus reducing the possibility of repeatedly opening the sorting roadway; taking the similarity coefficient of the order item as the basis of thecorrelation; establishing a multi-target goods allocation optimization model by comprehensively considering item sorting frequency and goods shelf gravity center; solving by adopting an improved invasive weed algorithm to obtain an optimal storage position of goods; generating a part of initial population by adopting a greedy algorithm; setting a reasonable spatial diffusion operator; and finallyintroducing an evolutionary reversal operation of a genetic algorithm. According to the goods location distributing method, the global search capacity and the local search capacity are high, and theoptimization effect is remarkable, and the warehouse sorting efficiency and the shelf stability are effectively improved.

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...
