      In a previous work ([3]) we proved that the Nguyen's condition for $[f(\w A)]_\alpha$ to be equal to $~f(A_\alpha)~$ also holds for the most general class of the $L$-fuzzy subsets, where $~L~$ is an arbitrary lattice. Here ...

      In the course of the studies on fuzzy regression analysis, we encountered the problem of introducing a distance between fuzzy numbers, which replaces the classical (x-y)² on the real line. Our proposal is to compute such ...
