Failure mode and effect analysis (FMEA) is one of the most powerful reliability analysis techniques for identifying and preventing potential risks across various fields. Current FMEA methods, while effective, still present several shortcomings. First, the crisp numbers cannot effectively elicit experts' fuzzy evaluations. Second, the weight of risk factors (i.e., occurrence, severity and detection) are assumed to be equal, which cannot reflect their different importance. Third, the traditional calculation method for risk priority is coarse and lack practical implications. There may exist the situation that two failure modes have the same risk priority number but with different risk levels.
