What is fuzzy variable?

Answer 1

A fuzzy variable is a concept from fuzzy logic that represents uncertain or imprecise information. Unlike traditional variables that have clear, defined values, fuzzy variables can take on a range of values, often expressed in terms of degrees of membership in fuzzy sets. This allows for more nuanced modeling of real-world scenarios where boundaries are not strictly defined, enabling better decision-making in situations with ambiguity or vagueness.
