Application of the fuzzy analytic hierarchy process to the failure mode and effects analysis

FMEA - is a technique used to study potential failures of various products. The probability of occurrence (O), the likelihood of severity (S) and the probability of detecting defects (D) can be used as an indicator of the priority risk number (PRN). Comparison of various methods for determining the priorities of failure modes in the calculated FMEA analysis is carried out. The value of the fuzzy PRN and fuzzy analytic hierarchy process (AHP) is proposed for determining the weights of risk factors. A method is proposed to eliminate some of the disadvantages of the traditional approach. As a result of the study, a mathematical model and methodology were created to identify high-priority types of errors based on fuzzy FMEA - AHP.
