A new method for fuzzy multiattribute group decision making based on intuitionistic fuzzy sets and the evidential reasoning methodology

摘要

This paper proposes a new method for fuzzy multiattribute group decision making based on intuitionistic fuzzy sets and the evidential reasoning methodology. The proposed method uses the evidential reasoning methodology to aggregate each decision maker's decision matrix and the weights of the attributes to get the aggregated decision matrix of each decision maker. It can overcome the drawbacks of the existing methods for fuzzy multiattribute group decision making in intuitionistic fuzzy environments.
