| Abstract(in English) | Modern railway signaling systems are becoming more and more complex with the increased use of software. Conventional safety assessment methods like FMEA and FTA usually work on the basis of component failures and try to trace propagation of those failures through the system. However, using these methods, it is difficult to erase the concern about scenario rationality or how a software failure influences the safety. That is why, STAMP (System Theoretic Accident Model & Process) is drawing attention for safety assessment. STAMP is an accident model that focuses on various module interactions, controls and feedbacks. RAMS standard for railways (IEC62278) requires qualitative as well as quantitative safety assessment of all Railway systems whereas STAMP provides only qualitative assessment. Main target of this paper is to compare FTA and STAMP method by applying on same system and later proposal for a new idea shall be made to incorporate STAMP in safety evaluation of railway signaling systems. |
