Modeling With Fuzzy Sets

Paul Flondor

Abstract

One of the first reasons for introducing fuzzy sets was that of the difficulties encountered by the classical set theory in dealing with vagueness. Once vague concepts are asserted, it seems hard to describe their extensions as "crisp" sets. In this paper we try to analyse the situation and see if fuzzy sets theory can do better. To make this analysis more specific we shall consider the concept "tall" which is almost unanimously declared to be vague
