Abstract:

In terms of the high security characteristics of the underground railway interlocking system, dynamic fault tree analysis method is often used. But the increasing of computational complexity is brought by the increasing of the fault tree. This paper uses common cause failure factor replacing the Hot Spare Door of dynamic fault tree, so that the computation is reduced.

Key words: common cause failure, dynamic fault tree, markov chain, reliability analysis, underground railway interlocking system
