Abstract :− This paper focuses on the study of two characteristics of trapezoidal intuitionistic fuzzynumber insert ignore into journalissuearticles values(TRIFN);, viz., Value index and Ambiguity index. Based on these two indexes, we develop analgorithm for ranking of trapezoidal intuitionistic fuzzy number insert ignore into journalissuearticles values(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
