基于Petri网,研究了成组技术中零件成组问题的实现方法.由于Petri网具有建模并发和并行处理能力,使得这种方法具有简单快速的特点,同时具有近乎人脑的并行工作机制,可以根据临场经验自动调整分配策略,将零件自主地分配到相应的零件组中.实际上,这种方法是一种启发式策略. Based on Petri net, this paper studies the method of component grouping in group technology.Because Petri nets have the ability of modeling concurrency and parallel processing, this method has the characteristics of simple and fast, at the same time, it has almost parallel working mechanism of human brain, According to the experience of the field can automatically adjust the distribution strategy, the parts are autonomously assigned to the corresponding part group.In fact, this method is a heuristic strategy.
