An Estimation Method of System Performance Degradation State Based on Fault Tree Method

摘要：

The performance degradation data can provide useful information about the reliability assessment for highly reliable and long-lifetime products. Existing system-level degradation tests may encounter many difficulties in degradation model building and the test might be difficult to carry out. This paper introduces the concept “State value, presents a system performance degradation state estimation method based on fuzzy fault tree method using the degradation data of components and subsystem, and conducts a preliminary validation.
