首先阐述了Petri网的基本原理,在此基础上利用“Petri网仿真器”建立交通运输网络模型,通过具有并发机制的编程语言来实现求交通运输网络最短路径的基本算法,然后针对该基本算法存在的缺陷,在假设前提下,提出了改进的仿真算法。
First of all, the basic principle of Petri nets is expounded. Based on this, the model of transportation network is established by using “Petri net simulator” and the basic algorithm of seeking the shortest path of transportation network is realized through the programming language with concurrency mechanism. The basic algorithm of the existence of defects, in the premise of the hypothesis, an improved simulation algorithm.
