Since fuzzy numbers represent uncertain numeric values, it is difficult to rank them according to their magnitude. In this paper, a new method for ranking fuzzy numbers is proposed. The method considers the overall possibility distributions of fuzzy numbers in their evaluations for ranking and provides users with a method changing viewpoints for evaluations. Users represent their viewpoints with fuzzy sets. The method evaluates fuzzy numbers with a satisfaction function and the viewpoint given… CONTINUE READING
