Abstract: A new TOPSIS decision making approach is proposed for hybrid multi-attribute group decision making problem with linguistic information and intuitionistic fuzzy values. Firstly, A new conversion function is defined to transfer multi-granularity linguistic information into intuitionistic fuzzy numbers. Then, based on the theory of intuitionistic fuzzy value entropy, a model is established to judge the expert’s weight. Next, Intuitionistic fuzzy weighted averaging (IFWA) operator is utilized to aggregate individual opinions of decision makers, and TOPSIS is used to rank alternatives. Finally, an example for ERP selection is given to illustrate the effectiveness of intuitionistic fuzzy TOPSIS method.

Key words: group decision-making, linguistic evaluation, intuitionistic fuzzy value, entropy, TOPSIS
