Ranking Trapezoidal Fuzzy Numbers Based on Apex Angles

Salim Rezvani

In this paper, we calculation ranking of trapezoidal fuzzy numbers based on apex angles. In fact, the concept of an aggregation operator for fuzzy numbers based on the arithmetic means of the corresponding L- and R- apex angles is extended for a class of Fuzzy Numbers. This method provides the correct ordering of trapezoidal fuzzy numbers and also the this approach is very simple and easy to apply in the real life problems. For the validation, the results of the approach are compared with different existing approaches
