Embodiment Construction

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

[0026] The present invention provides a mixed optimal dispatching method for a shuttle car and an elevator, which is specifically implemented according to the following steps:

[0027] Step 1 establishes a reasonable mathematical model for the dispatching situation of an elevator with a set of shuttle car (1:1 type);

[0028] 1.1 Analyze and study the fully automatic three-dimensional warehouse of the shuttle bus, and formulate the rules for cargo storage and withdrawal

[0029] 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 mother car walking track (roadway), the child car walking track (shelf row), the shuttle shelf, the pallet vertical lifting system ( Lift), pallet conveying system, CMS equipment control system, WMS warehouse manageme...

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 dispatching in and out of intensive storage, and in particular relates to a hybrid optimal dispatching method of a shuttle bus and an elevator (1:1 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...
