신뢰도 경로의 고장열거를 이용한 시스템 신뢰도 계산방법 연구

초록

Recently, System including aircraft, train, and ship is more complex and huger. Accordingly, Reliability calculation of these systems is more difficult. This paper is the study about reliability calculation algorithm of complex system that is difficult to analyze solution. If system has simple series structure or parallel structure in reliability block diagram, we can easily find analytical solution. But when system has very complex structure, we are very difficult to find analytical solution of the system. In this case, we can assess system reliability using failure enumeration method of reliability path. This research represent reliability block diagram by adjacent matrix and define reliability path. We can find any system status by failure enumeration of reliability path. As a result, we can calculate any kinds system reliability through this process. This result can be applied to RCM(Reliability Centered Maintenance) and Reliability Information Management System that requires system reliability being composed by reliability of individual part.
