Application of Reliability based Inspection for an Effective RCM Approach of Railway System

철도시스템의 효과적 RCM접근을 위한 신뢰성 기반 검사(RBI)적용

In the current railway industry in Korea, a lot of researches and studies have been progressed to establish RAMS process and construction of RCM system in accordance with international standards. On the point of view of applying the RCM to the railway system, many problems (i.e., reliability of the existing field data, the lack and incorrectness of failure information, etc) are described. To solve these problems, it is need to study and effort the RCM, practically. In this paper, lots of problems and solutions for methods determining the preventive maintenance interval of application of the RCM will be described. To do this, the method using the theory of RBI (Reliability Based Inspection) which is applied to the existing chemical plants and power plants is described. From this study, it is expected that in this situation that the quantitative data is not enough, the results that an analyst quantifies the qualitative factors and/or items will be a good reference that can effectively approach, on the side of determination about each maintenance task and inspection interval.
