摘要
以流水生产线为例,介绍了Petri网建模及其在制造系统中的性能分析。通过转换成马尔科夫链,可以计算变迁实施时间为指数分布的Petri模型的性能指标。并且针对Petri网模型计算复杂的特点,介绍了一种新的Petri网仿真方法——利用WITNESS软件对Petri模型进行仿真分析。
In this paper we introduced an two-machine and one-buffer petri model and its performance analysis.GSPN whose transiton obeys the exponetianl distribution could be converted into Markov chain. machine utilization and other perfomance could be worked out by this way. A new simulation method for Petri net------simulation with Witness was brought out to reduce the complex computation and programming.
