Abstract

Track guidance vehicle (RGV) is widely used in logistics warehousing and intelligent workshop, and its scheduling effectiveness will directly affect the production and operation efficiency of enterprises. In practical operation, central information system often lacks flexibility and timeliness. By contrast, mobile computing can balance the central information system and the distributed processing system, so that useful, accurate, and timely information can be provided to RGV. In order to optimize the RGV scheduling problem in uncertain environment, a genetic algorithm scheduling rule (GAM) using greedy algorithm as the genetic screening criterion is proposed in this paper. In the experiment, RGV scheduling of two-step processing in an intelligent workshop is selected as the research object. The experimental results show that the GAM model can carry out real-time dynamic programming, and the optimization efficiency is remarkable before a certain threshold.

2. Main Focus Of The Article

Many researches now studying the rail guided vehicle (RGV) mainly focus on the loading/unloading under certain distributions of the equipment. And most of them use artificial intelligence and machine learning to find the most efficient solution. But these methods require a great deal of data and cost much time. Meanwhile, what we are trying to solve is to figure out the optimal distributions of the equipment to save as much time as possible. So, from the perspective of the problem, what we are interested is a little bit more difficult and complicated since there are more uncertainties. Moreover, from the perspective of the modeling, we don’t have so much data that we can rely on to do the experiment and we need the models to give better solutions as soon as possible. On the whole, there are not so many researches we can refer to and we construct this dynamic model in a creative way.
