In this paper, we introduce a function in order to measure the distance
between two order intervals of fuzzy numbers, and show that this function is
a metric. We investigate some properties of this metric, and finally present
an application. We think that this study could provide a more general
framework for researchers studying on interval analysis, fuzzy analysis and
fuzzy decision making.
