Recently, Guha and Chakraborty studied a new approach to fuzzy distance measure and similarity measure between two generalized fuzzy numbers. In this paper, we propose a family of fuzzy distance measures between arbitrary fuzzy numbers depending on a defuzzification, an interval similarity measure, and some real pseudosemimetrics, involving some of the most important possibilistic and geometric characteristics of any fuzzy number. Then, we study its metric properties and its relationship with a partial order on the set of all trapezoidal fuzzy numbers. Illustrative examples about the action of this class of metrics are shown, comparing them with the results obtained by other researchers. Finally, as application, we introduce a fuzzy ranking and we compare it with other techniques. Keywords Similarity measure Fuzzy number Fuzzy distance Ranking Distance measure
