Abstract: Wire electrical discharge machining process offer opportunities to manufacturers to improve their technology, competitiveness and profitability through a highly efficient and focused approach to manufacturing effectiveness. Justification, evaluation and selection of WEDM process parameter now have been receiving significant attention in the manufacturing environment. Evaluating alternative WEDM process parameter in the presence of multiple conflicting criteria and performance measures is often a difficult task for the decision-maker. Preference ranking tools are special types of multi-criteria decision-making methods in which the decision-maker's preferences on criteria are aggregated together to arrive at the final evaluation and selection of the alternatives. This paper deals with the application of five most potential preference ranking methods for selecting the best WEDM process parameter for desired output characters ices for different aluminium metal matrix composite.
