Abstract :− This paper focuses on the study of two characteristics of trapezoidal intuitionistic fuzzynumber (TRIFN), viz., Value index and Ambiguity index. Based on these two indexes, we develop analgorithm for ranking of trapezoidal intuitionistic fuzzy number (TRIFN). Furthermore, we present anapplication of this ranking method in multi attribute group decision making problem. An illustrativenumerical example demonstrate our approach to multi attribute group decision making problem
Keywords : − Value, ambiguity, ranking, trapezoidal intuitionistic fuzzy numbers, multi attribute groupdecision making
