An Approximate Algorithm for Top-Event Occurrence Rate of Dynamic Fault Trees;

In order to solve this problem,a new method for designing BIT fault diagnosis strategy for fault-tolerant systems,considering reliability and testing costs,was proposed based on dynamic fault tree model.

In case of applying the dynamic fault tree to the quantitative analysis of dynamic system,it is difficult to use Markov theory directly when the dynamic sub-tree is very complex.

Due to the difficulty of multi-state fault tree analysis, a new method based on Bayesian networks is proposed by means of an example of multi-state radar system.
