Abstract

Quantitative RAM (Reliability, Availability, Maintainability) is the one of the important indicator that shows the quality of rolling stock. It is usually required in the domestic and abroad purchase specification of rolling stock. And achieving and demonstrating the quantitative RAM goals is also required. In this study, the method to set up these goals will be proposed in the aspects of service and logistic reliability, operational, achievement or inherent availability and maintainability. And we apply this proposed method to the real operation data.

정량적 RAM(Reliability, Availability, Maintainability)은 철도차량의 품질을 나타내는 중요한 척도중 하나이다. 국내외의 철도차량 구매사양서에서는 정량적 RAM 요구조건이 제시되고 있으며 이에 대한 달성과 입증을 요구하고 있다. 본 연구에서는 철도차량의 정량적 RAM의 목표값을 설정하는 방법을 서비스 신뢰도, 로지스틱 신뢰도, 운영가용도와 성취가용도 또는 고유가용도, 유지보수성 측면에서 제안한다. 그리고 이 설정방법을 실제 철도차량 운영데이터에 적용해 보았다.
