Abstract:
In this paper we study two rationality indicators and two normality indicators of a fuzzy choice function. They express the
degree of rationality or normality of this fuzzy choice function. This way we can establish a hierarchy in a given family
of fuzzy choice functions with respect to their degree of rationality.
