Introduction
It is an extension of Boolean logic.
It variable may have truth value that ranges in degree between 0 and 1.
It is a method of reasoning that resembles the human decision-making methodology.
Terminology
Fuzzy Relation
Fuzzy Variable
Fuzzy Set
Advantages
Easy to construct.
Helps to solve complex problem.
Fuzzy logic sometimes uses only approximate data, so simple sensors can be used.
Disadvantages
There no systematic approach to fuzzy system designing.
It may not give accurate reasoning sometime.
Understandable only when simple.
History
It was studied since 1920s.
Introduced by Lotfi Zadeh in 1965.
