Abstract: The notion of Intuitionistic Fuzzy Set (IFS for short) theory by Krassimir Atanassov strikes a paradigm shift in solving decision making problems, which is one of the crucial problems in our real life. Ranking of IFS and Interval Valued Intuitionistic Fuzzy Sets (IVIFS for short) is very often required in decision making. In this paper, we develop an aggregation operator for aggregating Intuitionistic fuzzy sets as well as interval valued intuitionistic fuzzy sets. It appears to be more elegant and simple than the existing aggregation operators. We also propose a score function and an accuracy function to rank the aggregated alternatives. It is illustrated with an example.
Keywords: Intuitionistic fuzzy sets, Interval-valued intuitionistic fuzzy sets, Aggregation operator.
