초록

일반적으로 FMECA는 시스템에 치명적인 영향을 줄 수 있는 장치나 고장모드를 파악하고 우선순위를 판단하여 이를 설계나 시스템 유지보수에 반영할 때 사용할 수 있는 기법이다. 본 논문은 도시철도차량의 차상 신호설비인 ATC/ATO 시스템에 FMECA를 이용하여 도시철도차량의 운전장애 현상을 정량적으로 분석하고 위험요소를 도출한 다음 이를 제거하여 도시철도차량의 운전환경을 개선할 수 있도록 하는데 목적을 두었다. 이를 위해 본 연구에서는 FMECA를 활용한 분석을 통해 ADU 개선방안과 사례를 제시하였다.

In general, FMECA is a technique for identifying failure modes and devices which could result in fatal outcomes. Also it can be used in design or in maintenance through establishing priorities. The purpose of this paper is aimed at improving the driving conditions in advance through analyzing the operation failure phenomena quantitatively with FMECA analysis on the onboard signal system equipped with ATC/ATO, and through deriving the risk factors. This paper suggests an alternative solution for improving the performance of ADU by analyzing a case with FMECA.
