Fuzzy Fault Tree Analysis Based on T-S Model

Abstract

A new approach of T-S model based fuzzy fault tree is presented. By introducing the fuzzy logic and T-S model, the new fuzzy fault tree analysis is capable of handling the fuzzy information, and dealing with the uncertainty of the event and fault relation without the exact information about the fault probability and failure mechanism. A simulation example of the reliability analysis in INS/GPS navigation system is given for illustration.
