Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0026] The present invention provides a hybrid optimal scheduling method for shuttle bus and elevator, which is specifically implemented according to the following steps:

[0027] Step 1 Establish a reasonable mathematical model for the dispatching situation of a lift with a set of shuttle vehicles (1:1 type);

[0028] 1.1 Analyze and research the fully automatic three-dimensional warehouse of shuttle bus, and formulate the rules of goods storage

[0029] See figure 1 , The shuttle car fully automatic three-dimensional warehouse includes: shuttle car (composed of child car and mother car), mother car walking track (lane), child car walking track (shelf row), shuttle rack, pallet vertical lifting system ( Lift), pallet conveying system, CMS equipment control system, WMS warehouse management system. Convert the actual shuttle car into a fully automatic three-dimensional w...

Abstract

The invention discloses an optimal dispatching method for warehousing systems combining rail guided vehicles and lifts. With the minimum dispatching travel time as the target, a dispatching warehouse-out and warehouse-in model is optimized through the genetic algorithm, the storing and delivering travel time is greatly shortened, the time cost is obviously reduced, the energy is saved, the advantages of the high efficiency, the high density and the high utilization rate of rail guided sub-vehicle full-automatic stereoscopic warehouses can be given full play to, real-time and online optimal dispatching of the automatic stereoscopic warehouses can be realized, and the practical application significance is great.

Description

Technical field [0001] The invention belongs to the technical field of inbound and outbound scheduling of dense warehouses, and specifically relates to a hybrid optimization scheduling method of a shuttle bus and elevator (1:1 type). Background technique [0002] With the rapid development of science and technology and industrial production, and the rise of the concept of "intensive storage", modern enterprises continue to increase their production, warehousing and distribution requirements, prompting the storage method to change from simple accumulation by manual labor to forklifts, etc. The warehouse-style storage of simple equipment is improved into a three-dimensional warehouse storage that currently uses automated equipment such as high-position forklifts, unmanned guided vehicles, AGVs, and shuttles. Rail shuttle vehicles (RGV) are playing an increasingly important role in modern manufacturing, logistics and other industries due to their high speed, low cost and good stabil...
