John, Robert Type 2 fuzzy sets: an appraisal of theory and applications. (English) Zbl 1087.68639 Int. J. Uncertain. Fuzziness Knowl.-Based Syst. 6, No. 6, 563-576 (1998). Summary: This paper provides a guide and tutorial to type 2 fuzzy sets. Type 2 fuzzy sets allow for linguistic grades of membership thus assisting in knowledge representation. They also offer improvement on inferencing with type 1 sets. The various approaches to knowledge representation and inferencing are discussed, with worked examples, and some of the applications of type 2 sets are reported.
