Abstract :
Ranking of fuzzy numbers play an important role in decision-making, optimization, forecasting etc. fuzzy numbers must be ranked before an action is taken by a decision. In this paper, a new approach based on the left and the right area of fuzzy numbers is proposed for ranking of non-normal and normal trapezoidal and triangular fuzzy numbers. This method contains simpler calculation than other ranking methods in comparison.
