Problems solved by technology

However, domestic and foreign scholars' research on shuttle vehicles is mostly based on static scheduling, and rarely involves dynamic mixed scheduling. The three-dimensional warehouse and the current imperfect shuttle racks can no longer meet the needs of today's market

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The present invention provides a 1:2 type elevator and a shuttle car mixed optimal scheduling method, which is specifically implemented according to the following steps:

[0037] Step 1 establishes a reasonable mathematical model for the case of one elevator with two sets of shuttle cars (1:2);

[0038] 1.1 Analyze and study the fully automatic three-dimensional warehouse of the shuttle bus, and formulate the rules for cargo storage and withdrawal

[0039] see figure 1 , The fully automatic three-dimensional warehouse of the shuttle car includes: the shuttle car (composed of the child car and the mother car), the shuttle rack, the mother car walking track (roadway), the child car walking track (shelf row), the pallet vertical lifting system ( Lift), pallet conveying system, CMS equipment control system, WMS warehouse management system. Will ...

Abstract

The invention discloses a lifter and shuttle vehicle combined warehousing system dispatch optimizing method. Minimization of the dispatch travel time is taken as the target, a genetic algorithm is used for optimizing a dispatch in-warehouse-in and out-warehouse model, the access travel time is greatly shortened, the time cost can be obviously saved, and energy is saved. In addition, for the same order, the travel time spent by two sets of secondary and primary shuttle vehicles is shorter than that spent by one set of secondary and primary shuttle vehicle. The beneficial effects of high efficiency, high density, the high utilization rate and the like of a secondary and primary shuttle vehicle full-automatic stereoscopic warehouse are given into full play, real-time and online dispatch optimizing of the automatic stereoscopic warehouse is achieved, and the method is of high significance in practical application.

Description

technical field [0001] The invention belongs to the technical field of dispatching in and out of intensive storage, and in particular relates to a hybrid optimal dispatching method of an elevator and a shuttle car (1:2 type). Background technique [0002] With the rapid development of science and technology and industrial production, and based on the rise of the concept of "intensive storage", the requirements of modern enterprises for production, warehousing and distribution have been continuously improved, and the storage method has changed from the simple accumulation of manual work at the beginning to the use of forklifts, etc. The warehouse-style storage of simple equipment is improved to the three-dimensional warehouse storage that currently uses automation equipment such as high-position forklifts, unmanned guided vehicles AGV, and shuttle vehicles. Rail shuttle vehicle (RGV) is playing an increasingly important role in modern manufacturing, logistics and other indust...
