Reliability Analysis of Safety-Critical System Based on Improved Dynamic Fault Tree Analysis Method
摘要
Abstract
Accounting for neglecting repairable attributions or system redundancy in traditional reliability analysis, a new modular dynamic fault tree analysis method is proposed by bringing repairable factors into formalized system reliability modeling. In the process of modular analysis both dynamic and static, the state combination explosive problem is avoided by adopting the approximation algorithm based on the Markov model and the probability of the top events, which improves the accuracy of Safety-Critical System(SCS) estimation results.关键词
