MULTI-OBJECTIVE OPTIMIZATION OF WIRE EDM PARAMETERS BY APPLYING MOORA TECHNIQUE

Abstract

The application of optimization techniques is essential for a manufacturing unit to respond effectively to ruthless competitiveness and increasing demand of quality product in the market. In this study, multi-objective optimization on the basis of ratio analysis (MOORA) technique was used to solve different decision-making problems and optimize the machining parameters in the wire electrical discharge machining processes for different materials. Five decision making problems requiring determination of optimum machining parameters using different techniques are considered in this paper. In all these cases, the obtained results using the MOORA technique compared with those suggested by the past investigators and the results demonstrate the simplicity, suitability, possibility, and flexibility of this technique when finding the solution for different complex decision-making problems during machining setting.
