Constructing Reliability Analysis Model of Complex Systems Based on FMEA-FTA-BN

Abstract:

In order to solve the difficulties existing in course of complex system reliability modeling, a novel method was proposed in this paper. According to the analysis sequence, from FMEA to FTA to BN, a BN can be constructed by making full use of the helpful information in the results of FMEA and FTA. The reliability of complex system can be analyzed based on uncertainty-expression ability and bidirectional-reasoning ability of BN. For demonstrating the effectiveness of this method, aim at the failures of gears in wind turbine gearbox, a BN for system reliability analysis was constructed.
