Abstract

A new dynamic fault tree analysis method based on discrete-time Bayesian networks is proposed. The conversion of the dynamic logic gates

such as priority and gate

sequence enforcing gate

spare gate and functional dependency gate to discrete-time Bayesian networks is studied. The top-event probability

importance measures and other diagnosis and prediction results can be obtained subsequently using the classical algorithms based on Bayesian networks. The comparison with Markov chain method is carried out by means of the digital aviation control computer system

and the results show that the proposed method can guarantee high accuracy

and the relative errors are no more than 0.4%. In addition

the proposed method can be easily extended to multi-state systems with non-determinate logic relations.
