Abstract: Some parameters for intuitionistic fuzzy numbers are introduced: value, ambiguity, width and weighted expected value. Trapezoidal approximation operators given in previous papers are expressed by these parameters.
Keywords: Fuzzy number, Intuitionistic fuzzy number, Trapezoidal fuzzy number, Value, Ambiguity, Width, Expected value
