Reliability Path와 Cut을 이용한 시스템의 신뢰도 계산방법에 관한 기초연구

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 using reliability path and cut 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 and cut. This research represent reliability block diagram by adjacent matrix and define reliability path and cut. We can find any system status by failure enumeration of reliability path and cut. As a result, we can calculate any kinds of system reliability through this process. This result can be applied to RCM(Reliability Centered Maintenance) and web-based Reliability Information Management System that requires system reliability being composed by reliability of individual part.
