AB - This paper presents a fuzzy rule-based FMEA applied to the power management system (PMS) of hybrid vessels to complement the qualitative limitations of conventional FMEA and to reflect the operational  context  of  complex  systems.  The  proposed  method  extends  conventional  subjective evaluation  into  a  quantitative  model  based  on  fuzzy  logic,  thereby ensuring the consistency and objectivity of risk assessment. Occurrence, severity, and detectability are modeled as triangular fuzzy numbers(TFNs) on a five-level linguistic scale, and a fuzzy risk-priority number(RPN) is derived through product t-norm inference and centroid defuzzification(Δx = 0.1, output scale [0–100]). In a case study on output short-circuit, input overvoltage, and overheat protection, the fuzzy RPN corrected over- and underestimation versus the traditional RPN(e.g., 84→73.5, 72→66.2,   56 → 58.3).   The   results demonstrate improved diagnostic accuracy, reproducibility, and general applicability of the proposed approach, which is practical for test/inspection resource allocation,  protection-logic retuning,  and extensible to weighted RPN(WRPN), FTA coupling, and digital-twin-based online risk management.
