A Group Decision Making Approach Based on Newly Defined Additively Consistent Interval-Valued Intuitionistic Preference Relations

摘要: Because of the complexity interval-valued intuitionistic fuzzy set, there are few literatures investigating additive consistency preference relation. This paper proposes a group decision making approach with relations. Firstly, two reciprocal relations and non-preferred obtained by dividing an relation in order to avoid operations numbers. Here, is interpreted as intensity one alternative over another one. Moreover, rational concept defined. Secondly, optimizing models derive priority weight vector from constructed. In particular, terms numbers, which under environment. Thirdly, extended address (GDM) problems proposed. Each individual expert’s index applied measure his/her degree importance. Finally, illustrative example supplier selection provided illustrate proposed addressing GDM problems. The feasibility numbers using developed verified. And compared other conventional existing ones show its advantages.
