Chapter 4 Fundamental Concepts of Fuzzy Logic
Term Set
The collection of fuzzy sets that define the semantics of a variable is called
the variable’s term set. Each variable used in a fuzzy rule must have a
term set. The individual fuzzy sets in a term set are the linguistic variables
associated with the variable. Thus, Tall in the rule if height is Tall then
weight is Heavy is part of the term set for the variable height and Heavy
is part of the term set for the variable weight.
Universe of Discourse
The complete range of values over which a variable can assume values
is called the universe of discourse (UoD). Although this term is often
applied to
