A note on 'Ranking generalized exponential trapezoidal fuzzy numbers based on variance'

摘要

It is well known that the ranking of generalized fuzzy numbers depend upon the height of fuzzy numbers. In this note, it is shown that the method, proposed by Rezvani [Applied Mathematics and Computation 262 (2015) 191-198] for ranking of generalized exponential trapezoidal fuzzy numbers, is independent from height of fuzzy numbers. Hence, it is not genuine to use this method for ranking of generalized exponential trapezoidal fuzzy numbers.
