Abstract: Failure Mode and Effect Analysis (FMEA) is a mitigative risk management tool which prevents probable failures in the system and provides the foundation for policies and remedial measures to tackle them. In this article, a method called Fuzzy Risk Priority Ranking (FRPR) is proposed based on fuzzy if-then rules and determination of fuzzy rule-based Risk Priority Number (RPN). The different combination modes of risk factors (i.e. severity (S), occurrence (O), and detection (D)) are prioritized between 1 and 1000. Comparing between FRPR and RPN approaches, and an illustrative example of an aeronautical gas turbine system the merits of the proposed method are explained.
