摘要
The ranking of interval-valued intuitionistic fuzzy numbers (IVIFNs) is very important for fuzzy decision making problems. This paper presents a geometric approach for ranking IVIFNs. Based on the technique for order performance by similarity to an ideal solution, this method is applied to group decision-making in an intuitionistic fuzzy environment. First, all individual decisions with IVIFNs are aggregated into a collective decision. Next, the ideal solutions of collective decision are established. Then the alternatives are ranked based on the geometric method presented in this paper. The practicability, feasibility and effectiveness of the proposed method is illustrated by an experimental analysis. (C) 2016 Elsevier Ltd. All rights reserved.
