Information fusion for intuitionistic fuzzy decision making: An overview

•Make an overview of intuitionistic fuzzy decision making theories and methods.•Give a survey of the applications of those theories and methods.•Suggest some possible directions for future research.

Intuitionistic fuzzy decision making is to find the suitable method for ranking alternatives based on the provided intuitionistic fuzzy information or some related attributes. To date, many studies have focused on intuitionistic fuzzy decision making problems and various decision making methodologies and approaches have been proposed. To provide a clear perspective on the information fusion for intuitionistic fuzzy decision making, this paper presents an overview on the existing intuitionistic fuzzy decision making theories and methods from the perspective of information fusion, involving the determination of attribute weights, the aggregation of intuitionistic fuzzy information and the ranking of alternatives. Some potential challenges in future research are meanwhile pointed out. In addition, we provide a survey of recent applications of the discussed theories and methods in various fields.
