Abstract

Multi-Criteria Decision Making (MCDM) techniques are widely used for optimization of process parameters in various engineering problems. The weight allotted to each criterion plays a crucial role in effectively implementing MCDM techniques. In this work, we use the TOPSIS technique with five different subjective and objective weight allocation methods to select the best operating conditions for the machining of SKD11 tool using Electro Discharge Machining (EDM) process. Our results indicate that experimental runs no. 22 and 25 are the best alternatives among all the options tested. The rank plot also suggests that an increase in peak current is better for the overall performance of the EDM process. We observe that the TOPSIS method is not very sensitive to the criteria weights for the current dataset, as evidenced by the correlation between the ranks obtained using the two methods. Moreover, we find that the weights allotted have little effect on the predicted optimum process parameters in the case of the TOPSIS method.
