Ranking exponential trapezoidal fuzzy numbers with cardinality
Salim Rezvani
Marlik Higher Education Institute of Nowshahr
In this paper, we want to represent a method for ranking of two exponential trapezoidal fuzzy numbers. In this study a new Cardinality between exponential trapezoidal fuzzy numbers is proposed. Cardinality in this method is relatively simple and easier in computation and ranks various types of exponential fuzzy numbers. For the validation the results of the proposed approach are compared with different existing approaches.
Keywords: cardinality, exponential trapezoidal fuzzy numbers, ranking method
