Multi-criteria decision making method based on interval-valued intuitionistic fuzzy sets
- 32 Downloads
Multi-criteria group decision making is a widely used efficient decision methodology to improve quality of the decision. In this paper, the interval-valued intuitionistic fuzzy weighted arithmetic average operator, the interval-valued intuitionistic fuzzy weighted geometric average operator, and an accuracy function of interval-valued intuitionistic fuzzy value are introduced. The proposed aggregation operators with a accuracy function is more efficient to take decision. Finally, an example is provided to illustrate the application of the developed approach. The results show that the proposed new approach is more comprehensive and flexible by comparing with the other existing aggregation operators and accuracy functions.
