Reliability analysis of a satellite system considering common cause failures

According to the necessity of reliability analysis for satellite system subjected to common-cause failures, the unreliability expression under a variety of common-cause condition is developed to analyze the unreliability of satellite system in this paper. Based on static fault tree analysis of satellite system, the binary decision diagram is used to evaluate the reliability considering common-cause failures. The importance of prevention of common-cause failures in large structured redundancy system is verified by using practical calculation example.
