FMEA와 FTA의 조합에 따른 철도 시스템 안전성 평가

System stability and reliability analysis techniques, FMEA (Failure Mode and Effects Analysis) or FTA (Fault Tree Analysis) to the railway system by applying a Simultaneous system failures removal methods can complement. Current FMEA and FTA characteristics, different fault clearing as a method has been widely used in many areas. Accordingly in this paper, why Simultaneous Application of FMEA and FTA is suitable comparison/analysis, and present examples of applying these two techniques simultaneously on the railway system (hardware/software)
