Abstract: A method of supplementary variables for non-markovian stochastic Petri net is proposed, which fits for system that shares maintain resource reliability analysis. It studies analysis method of non-markovian stochastic Petri net based on supplementary variables. It takes a parallel system as an example to illustrate the new method of modeling process, solution method and gives expression of reliability indexes, and validates the feasibility of the method using exponential distribution.

Key words: Non-markovian stochastic Petri net, Supplementary variables, Reliability analysis
