Abstract
The most commonly used approach for ranking fuzzy numbers is ranking indices based on the centroids of fuzzy numbers. In this paper, we introduced a new ranking method which is based on multi-index such as relative dominance, priority weight and decision-makers preference. In addition to this we determined the feasibility and validity of this method by providing numerical examples.
Keywords: Fuzzy numbers, fuzzy relation, dominance-based approach, relative dominance, priority weight.
