混合动态系统SPN的稳态性能分析

The Stable State Performance Analysis of Hybrid Dynamical System's Stochastic Petri Nets Model

给出了混合动态系统SPN模型各状态的稳态概率存在解析解的条件,基于稳态概率,可以求出变迁利用率等几个稳态性能指标,从而实现分析该模型稳态性能的目的。同时为解决混合动态系统SPN模型状态空间爆炸的问题,在保持时间性能的前提下对该模型的几种特殊结构进行了简化。

The conditions under which stable state probability in hybrid dynamical system＇s stochastic Petri nets model has analytic answers are presented in this paper. By means of stable state probability, stable indexes such as transition＇s utilization ratio can be obtained to analyze stable state performance of the model. Furthermore, in order to solve the problem of state space explosion, some special structures of the model are simplified without changing time performance.
