Abstract :
The existing methods to evaluate reliability of phased mission system with multi-mode failures are all very complex. In order to solve this problem, a simulation model based on CPN is proposed in this paper. Firstly, A CPN model of components with multi-mode failures is proposed; secondly, the CPN models to deal with dependencies are presented. On this basis, the phase reliability CPN model and mission reliability CPN model are proposed. Compared with analytical algorithm DEP-BDD, this method not only makes modeling and analytical procedure simpler, but also keeps the error comparatively small and stable. Compared with Extend method, this model is more general.
