Abstract: The proposed integrated framework aims to detect the failure causes based on criticality of Milk Processing Unit (MPU). Fuzzy Multi Criteria Decision Making (MCDM) approach has been integrated with Failure Mode Effect Analysis (FMEA) approach. The FMEA approach was utilised to pinpoint potential failure causes within the MPU. Moreover, fuzzy ratings were collected pertaining to three distinct risk factors. The Fuzzy Combinative Distance-based Assessment (FCODAS) approach was integrated into a fuzzy FMEA to prioritise failure causes. The rankings derived from this analysis were compared with the results obtained from the decision-making approaches Fuzzy-Complex Proportional Assessment (FCOPRAS) and Fuzzy-Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS). To check the consistency of the result, sensitivity analysis was performed to assess the robustness of the integrated framework. The plant's maintenance manager was provided the analysis-based ranking results, and he stated his consensus with the attained outcomes.

Keywords: MPU; failure cause; FMEA; fuzzy; MCDM; risk.
