11. The output fuzzy sets for all the rules are then aggregated into a single fuzzy set . 12. His main research areas are fuzzy sets and fuzzy methodologies, many-valued logic and history of mathematics. 13. The values between 0 and 1 characterize fuzzy members, which belong to the fuzzy set only partially. 14. In a fuzzy set , each object is assigned a single evidence for membership and evidence against membership. 15. The term " fuzzy logic " was introduced with the 1965 proposal of fuzzy set theory by Tarski. 16. Since then, more and more researchers around the world are writing articles about type-2 fuzzy sets and systems. 17. Fril has predicates for fuzzy set operations ( but does not directly support control through fuzzy logic ). 18. Fuzzy sets were introduced by Zadeh ( 1965 ) as an extension of the classical notion of sets.19. It is widely accepted that Fuzzy sets are more suitable for representing preferences of criteria in decision making. 20. Engineers, statisticians and programmers nowadays often represent fuzzy concepts mathematically using fuzzy variables, fuzzy sets and fuzzy values.
