Fuzzy preference relations formalize intensity of individual preferenc
es over fixed sets of alternatives. It is therefore natural to extend
to fuzzy preferences the notion of rationality or consistency. With th
is goal in mind, we address in this paper the problem of giving an axi
omatic basis for defining the concept of fuzzy rationality. Specifical
ly, we establish a collection of conditions that any fuzzy rationality
measure must satisfy. Some examples of fuzzy rationality measures are
then given and analyzed.
