Updating the FMEA Approach with Mitigation Assessment Capabilities—A Case Study of Aircraft Maintenance Repairs

This paper proposes a qualitative model to overcome the limitations of conventional failure mode and effects analysis (FMEA), which does not consider risk mitigation capabilities when prioritizing risks. Failure these can lead unrealistic estimates, especially level uncertainty is high. In proposed model, original applicability FMEA was retained along with three variables, namely, severity, occurrence, detectability. addition, fourth variable added account for capabilities. A case study in project selection aircraft repairs used demonstrate implementation its applicability. The results show that inclusion options leads more realistic scenarios, suggesting approach may non-conservative estimates.
