| Abstract: | In this paper, decision making method based on the interval-valued intuitionistic trapezoidal fuzzy number is studied. Expected values, score function and accuracy function of interval-valued intuitionistic trapezoidal fuzzy number are defined. Based on these, an approach for raking interval-valued intuitionistic trapezoidal fuzzy number is proposed. On the other hand, the ordered weighted averaging operator and the hybrid aggregation operator are explored. Based on these operators, the model of multi-attributes group decision making is constructed. Furthermore, this paper proposes a method of decision making. An illustrative example is given to show the effectiveness of the method. |
