Abstract
Common cause failures (CCF) which probably consumedly reduce system reliability are important and complicated in system reliability analysis. GO methodology is an effective method for system reliability analysis even for a system with CCFs. Rationalization proposal was made to improve the accuracies of the previous algorithm. Whereafter a new algorithm was proposed. All common cause component groups (CCCG) can be dealed with together by a new GO chart to obtain system fault probability (FP) with only CCFs, then the system FP can be obtained. The new algorithm was then tested by analyzing two repairable systems with CCFs. All results consistently show that the new algorithm is a simple and available method for system reliability analysis with CCFs especially for the system with multiple CCCGs.
