The Multiple Criteria Decision Making MCDM is acknowledged as the most useful branch of decision making. It provides an effective framework for comparison based on the evaluation of multiple conflicting criteria. In this paper, a method is proposed to work out multiple attribute group decision making MAGDM problems with interval-valued intuitionistic trapezoidal fuzzy numbers IVITFNs using Elimination and Choice Translation Reality ELECTRE method. A new ranking function based on value and ambiguity is introduced to compare the IVITFNs, which overcomes the limitations of existing methods. An illustrative numerical example is solved to verify the efficiency of the proposed method to select the better alternative.
