Abstract

Large scale systems, the facilities for the production of power, gas and chemical, have the complex structures. Most systems require the high reliability for the improvement of process efficiency, but it is difficult to analyze the reliability of processes with complex structures. In this study, we investigated reliability path of chemical process with k-out-of-n system by reliability block diagram(RBD) and calculated the reliability of process through the failure enumeration method of reliability path. This method should help in analyzing the reliability of k-out-of-n system.

최근 발전, 가스 설비, 화학공장 등의 대형 시스템들은 매우 복잡한 구조를 지니고 있다. 대부분의 공정들은 효율성을 위하여 높은 신뢰성을 요구하고 있으나, 복잡한 과정으로 인하여 신뢰도 분석이 상대적으로 어려운 실정이다. 복잡한 화학공정에서의 신뢰성 분석을 위하여 이 논문에서는 k-out-of-n로 구성된 화학공정을 RBD를 이용하여 신뢰성 경로를 파악하고, 고장판정행렬을 적용하여 신뢰도를 계산하였다. 이 기법이 k-out-of-n 시스템의 신뢰성 분석에 유용하게 사용될 수 있다는 것을 제시하였다.
