Reliability analysis for non-repairable multi-state system under fuzzy Weibull failure rate

摘要

The purpose of this research is to present a methodology for analyzing the system reliability of the non-repairable multi-state system (NMSS) which the failure rate is Weibull distribution with uncertainty time. The vagueness coefficient with a triangular membership function is applied to analysis of the NMSS problem. From the proposed method, the fuzzy system reliability of NMSS is established with an assumption that failure rates is a fuzzy Weibull distribution. Finally, some numerical examples are presented to illustrate how to calculate the fuzzy system reliability of NMSS.
