철도시스템의 RAMS 중심의 유지보수 정책 결정을 위한 개념적 절차

초록

There are two main parts to improve the quality and the efficiency of railway service. One is to acquire the system with high RAMS performance and the other is to keep it up. Therefore we need to specify RAMS requirements in the system specifications and verify them. In addition, it is necessary to monitor RAMS and to make operation and maintenance policies based on RAMS. This article presents RAMS centered maintenance procedure of which target is to continuously achieve the inherent RAMS performance of the acquired system. The method to evaluate the effect on RAMS and the conceptual optimal model for determining maintenance interval are also proposed.
