Fuzzy Modeling
Fuzzy logic and fuzzy set theory were developed by Lotfi Zadeh in the 1960s and 70s while a professor at the University of California, Berkeley. Born to Persian and Jewish Russian parents in Baku, Azerbaijan, he completed his schooling in Tehran, Iran, and later moved to the USA, where he studied at MIT and Columbia. As a result, he was familiar with how concepts are understood in different cultures and expressed in different languages. This inspired his research approach to approximate reasoning and linguistic variables that he formalized as fuzzy theory.
Fuzzy set theory is an approach that can deal with problems relating to ambiguous, subjective, and imprecise judgments. Vagueness is inherent in everyday language, and fuzziness was invented to express this and work with it in an intuitive manner. Fuzzy logic expresses subjective belief and vagueness. It can and has been claimed that probability theory is a subset of fuzzy logic.
