Abstract: | In the traditional method for the reliability analysis of fault-tolerant system, the system structure is described by means
of binary decision diagram (BDD) and Markov process, and then the reliability indexes are calculated. However, as the size
of system augments, the size of state space will increase exponentially. Additionally, Markov approach requires that the failure
and repair time of the components obey an exponential distribution. In this study, by combining dynamic fault tree (DFT) and
numerical simulation based on the minimal sequence cut set (MSCS), a new method to evaluate reliability of fault-tolerant
system with repairable components is proposed. The method presented does not depend on Markov model, so that it can effectively
solve the problem of the state-space combination explosion. Moreover, it is suitable for systems whose failure and repair
time obey an arbitrary distribution. Therefore, our method is more flexible than the traditional method. At last, an example
is given to verify the method. |
