This paper presents an alternative approach based on fuzzy logic extension of VIKOR methodology for Criticality Analysis in Failure Modes Effects and Criticality Analysis (FMECA) technique. The aim of the proposed approach is to improve failure criticality analysis to overcome some recognized limits of the application of traditional US MIL-STD-1629A. The proposed approach has been tested by means of an industrial case study, dealing with an important Italian oil refinery. Finally, in order to assess methods and results robustness, an alternative sensitivity analysis is also proposed.
