An approach for ranking of fuzzy numbers

In order to rank all fuzzy numbers, we modify the method of “a new approach for ranking of trapezoidal fuzzy numbers” by Abbasbandy and Hajjari (2009). Our proposed method is used for ranking symmetric fuzzy numbers. The advantage of this method is illustrated by some comparative examples.

► In order to rank all fuzzy numbers, we modify Abbasbandy and Hajjari proposed method “a new approach for ranking trapezoidal fuzzy numbers”.
► We prove all properties in details.
► We show the accuracy and efficiency of the proposed method by obtained results from numerical examples.
