Parametric optimization of wire electrical discharge machining using TOPSIS method

In this paper, the application of techniques for order preference by similarity to ideal solution (TOPSIS) method is applied for solving a multiple criteria (objective) optimization problem in a wire electrical discharge machining process. Three examples are included to illustrate the approach. In all the cases, it is found that the results obtained using the TOPSIS method almost match those derived by past researchers which prove the applicability of this method in solving various complex decision-making problems in a present day manufacturing environment.
