Multi Criteria Decision Making Based on Classical α-Cut Approach

Abstract

Multi Criteria Decision Making (MCDM) is the process to find the best alternatives among a set of available alternatives in presence of various conflicting criteria. In this paper MCDM method is presented using α-cut approach and it is observed that α-cut approach is general enough to deal with MCDM methods. Here first fuzzy numbers have been assigned to quantify different qualitative criteria of alternatives and then their α-cut values are evaluated and then performed some arithmetic operation to order ranking of the alternatives. Finally, a decision making problem is carried out with different case studies by using different shapes of fuzzy numbers. Keywords: Multi criteria decision making, fuzzy numbers, α-cut of fuzzy number.
