Ranking Fuzzy Numbers by the Score Method

In this paper, we proposed ranking fuzzy numbers by using the score method. The main step is that we assume A = (a1,a2,a3,a4) is a fuzzy number.To obtain ranking index, the mean and standard deviation values are calculated from the convex combination of ai for i = 1,2,3,4. In the follow the proposed method is evalueted by some numerical examples and compared with other methods
