An Improved Fuzzy FMEA Model Based on MACBETH and VIKOR Method

Aiming at the shortcomings of traditional failure mode and effect analysis (FMEA) methods, an improved FMEA model based on the measuring attractiveness by a categorical-based evaluation technique (MACBETH) and the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method is proposed. First, the Q-order orthogonal fuzzy set is adopted to represent the evaluation information of experts. Second, the MACBETH is utilized to determine the weight of each risk factor. Finally, the VIKOR method is employed to calculate the risk priority of failure modes. Furthermore, an empirical case related to the risk assessment of the smart city information security is presented to verify the applicability and practicality of the proposed model.
