Fuzzy failure modes and effects analysis
Failure mode and effects analysis (fmea) is a popular and useful approach applied to examine potential failures in different products then weights of risk factors and fuzzy rating of failure modes are aggregated to get the fuzzy decision matrix and fuzzy weight of risk factors.
