Abstract :
In this paper, we present the rst moment have been dened based on the center of mass from the
fuzzy number, then with calculating area between the center of mass, a new ranking method has been
proposed. At last, we present some numerical examples to illustrate our proposed method, comparing
with distance index ranking method.
