Quantitative analysis to derive SIL in the railway signalling system

철도신호시스템의 정량적 분석 기법을 통한 SIL 도출방안 검토

It is very important to ensure system safety during the process of developing a system. Railway system is also devoting a great portion for the safety. Nowadays many countries leading railway industry have their own system assessment principles according to the situation of their train control systems. In this paper, several principles to derive Safety Integrity Level (SIL) are represented in the railway signalling system. The characteristics of those principles are also considered respectively.
