Abstract :
The modularization of dynamic fault tree and Markov chain solution for dynamic subtree are studied briefly. This paper presents the conversion from dynamic logic gate to Markov chain, the solution of dynamic subtree top event failure probability and the method of obtaining the failure mode of subsystem using Markov model. However, due to the possibility of state combinatorial explosion problem in Markov chain, it is difficult to analyze system with DFT in some cases. So a simple approach to solve dynamic fault tree is provided.
