| Abstract: | Many methods for ranking of fuzzy numbers have been proposed. However, these methods just can apply to rank some types of fuzzy numbers (i.e. normal, non-normal, positive, and negative fuzzy numbers), and many ranking cases can just rank by their graphs intuitively. So, it is important to use proper methods in the right condition. In this paper, a conceptual procedure is proposed to describe how to use intuitive ranking and some technical ranking methods properly. We also introduce a new ranking fuzzy numbers approach that can adjust experts confidence and optimistic index of decision maker using two parameters ( and  ) to handle the problems and find the best solutions. After illustrate many numerical examples following our conceptual procedure the ranking results are validity. |
