dc.description.abstractFuzzy numbers have been studied extensively in mathematics along with its applications in diverse fields, especially in solving many real-life problems. This research work based on an extensive survey of the related existing works, formulates a ranking method for generalized trapezoidal fuzzy numbers by computing section-wise perimeters of the trapezoid representing a generalized fuzzy number. The perimeter of trapezoid representing a generalized fuzzy number is viewed as comprising three segments:- left and right divergences which are right angled triangles and the centre as a rectangle. In order to evaluate its degree of robustness, new similarity measures are computed and finally compared with the related results obtained under other existing similarity measure approaches by way of providing a comparison table.en_US
