Abstract :
This work presents a safety analysis on an electronic equipment used on rolling stock in according to the international safety standard, IEC 61508. Alternative methods, the fault tree analysis (FTA) and the Markov-Chain analysis, are shown and discussed in this paper. Such methods allow to cover wider reliability configuration classes with respect to the formulas suggested in the standard.
