| 摘 要： | 本文首先引入了时延网和闭网的概念,证明了Petri网N为时延网的充要条件是其闭网为常返网;然后,从时延网模型出发,讨论了变迁发射时间为任意分布的随机离散事件系统时延特性的求取方法,给出了时延密度的计算公式。

| Abstract: | Time-Delay Net (TON) and Closed Net (CN) are introduced.It is proved that the necessary and sufficient condition of a Petri net being a TDN is its corresponding CN being recurrent.Then,from TON models the resarching approach for the time delay characteristics of discrete event systems with generally distributed activity durations is developed,and the equations used to compute systems' time delay distribution density functions are proposed. |

| Keywords: | stochastic Petri net discrete event system time delay |
