Ranking generalized exponential trapezoidal fuzzy numbers based on variance

摘要

In this paper, we calculate ranking of exponential trapezoidal fuzzy numbers based on variance. In this method, values are calculated by finding expected values using the probability density function corresponding to the membership functions of the given fuzzy number and provides the correct ordering of exponential trapezoidal fuzzy numbers and also 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.
