Research on the reliability of ship systems based on fuzzy FMECA

The structure of ship systems is complex, and there are many types of subsystems and components. When faults occur, there are many influencing factors, making it difficult to achieve accurate quantitative evaluation. Therefore, the traditional FMECA analysis method is adopted to divide the structure of the electromechanical system and quantitatively evaluate each fault mode; Combined with the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation Method, the system's fault hazard level was comprehensively quantified, which can provide theoretical and technical support for the analysis of ship fault modes and the determination of fault locations.
