Abstract: This work presents a fuzzy decision support system to optimise the performance issues of an effluent treatment plant (ETP) within an Indian milk process industry under the concern of environmental issues. The system employs a nonlinear fuzzy Jaya Lambda-Tau optimisation (JLTO) approach-based coding implemented in MATLAB for determining the reliability based performance parameters of the ETP unit. As the degree of uncertainty or vagueness increases, the system's performance based on availability parameter indicated towards decreasing trend. Furthermore, an analysis of potential risks is accompanied using failure mode and effect analysis (FMEA) technique with input from experts to improve the availability of the unit. To overcome the limitations of conventional FMEA approach, fuzzy COmplex PRoportional ASsessment (FCOPRAS) method is incorporated within FMEA modelling. The robustness of the suggested system is examined through sensitivity analysis.
