A New Hybrid Fermatean Fuzzy Set and Entropy Method for Risk Assessment

Risk evaluation is an important part of the product design and manufacturing process; it entails pursuit highest quality preventing failure under constraints limited resources. The mode effects analysis approach one most widely applied risk tools that uses three elements items, severity, occurrence probability, detection to calculate priority number, risk. However, typical method ignores consideration objective weights, which may lead incorrect results. Moreover, expressing information about provided by experts also directly affects results assessment. To comprehensively assess failure, in this study, hybrid Fermatean fuzzy set entropy was used prioritize items This study a service numerical example self-service electric vehicles illustrate test correctness proposed new method. mathematical operation were compared with listing different calculation methods. prove can fully consider cognitive provide more accurate ranking items.
