 abstract={Fuzzy number approximation by trapezoidal fuzzy numbers which preserves the ex­pected interval is discussed. Algorithms for calculating the proper approximations are proposed and some properties of the approximation operators are discussed. It is shown that an adequate approximation operator might be chosen through the comparisons of some characteristics of the fuzzy number, like its ambiguity and width or its value and weighted expected value.},
