Multiple attribute decision making under interval-valued hesitant fuzzy sets: An priority degrees approach

摘要

Against existing literature about decision-making methods having deficiencies in flexible and lacking of original information, this paper presents some priority degree formulas in interval-valued hesitant fuzzy sets. And the desirable properties of priority degrees are studied. Meanwhile, a new multiple attribute decision-making method based on interval-valued hesitant fuzzy sets is proposed. This method can retain the completeness of the inherent thoughts of decision makers properly and provide a reliable basis for evaluation. Examples are presented to demonstrate the applicability of the proposed approach in real situations, and make a comparison with the existing methods.
