一类PETRI网的时间性能简化分析

REDUCTION METHOD FOR TIME ANALYSIS OF A CLASS OF PETRI NETS

实际系统的Ｐｅｔｒｉ网模型中加入时间因素形成ＴＰＮ，在评价系统性能时，ＴＰＮ 的周期性具有重要意义．为降低系统的性能分析和计算的复杂性，基于分解的方法，结合结构简化分析，探讨具有同步连接时各分解子网与总网之间时间性能的关系，并给出一些典型结构的简化算法．

In the physical system,it is necessary to add time factor into model,and cycle time is important in the performance analysis.In order to decrease complexity of analysis and computation,we propose a decomposing method with structure reduction.When there are synchronized links between subnets,the cycle time compute algorithm and reduction method of special structure are given in detail in this paper.
