Abstract

Owing to the established international standards for reliability and safety management of railways and the third-part conformity assessment implementation, quantitative risk assessment focusing on communication system related to railway safety has being implemented. The quantitative risk assessment starts from the establishment of quantitative RAMS requirements; the risk has to be maintained under an acceptable safety level. This paper introduces the risk assessment process based on international standards ; risk assessment was conducted using failure data for railway facilities for about 5.5 years. In addition, based on the results, a scientific risk management method for railway facilities is suggested.

철도적용 신뢰성 및 안전성관리에 대한 국제표준 제정과 해당 국제표준에 대한 제3자 적합성평가의 정착으로 철도안전과 밀접한 신호시스템을 중심으로 정량적 위험도평가가 수행되고 있다. 이러한 정량적 지표를 활용한 위험도관리는 사고정의, 허용수준의 정량적 RAMS 목표수립으로부터 시작되어 운영기간 중 위험도가 허용수준으로 유지됨을 확인해야 한다. 본 논문에서는 기존 철도시설물의 5.5년간(2010년 1월~2015년 6월)의 관리장애 정보를 사용하여 국제표준에 따라 위험도 매트릭스를 활용하여 철도시설물 구간에 대한 위험도평가의 사례연구를 수행하였다. 또한, 분석된 데이터를 바탕으로 시설물의 과학적 위험도관리를 위한 방안을 제시한다.
