Call for Papers for the 25th Jubilee Edition of the International Conference on Intuitionistic Fuzzy Sets is now open!
Conference: 9–10 September 2022 • Deadline for submission: 30 May 2022.

Intuitionistic Fuzzy Sets: Theory and Applications

"Intuitionistic Fuzzy Sets", subtitle: "Theory and Applications" is the title of a book by Krassimir Atanassov, published in Springer Physica-Verlag Publishing house in November 1999 under ISBN 3-7908-1228-5. It is featured in the series "Studies in Fuzziness and Soft Computing" under Volume 35.

The book introduces the basic definitions and properties of the intuitionistic fuzzy sets, which are substantial extensions of the ordinary fuzzy sets. The most important property of IFS not shared by the fuzzy sets is that modal operators can be defined over IFSs. The IFSs have essentially higher describing possibilities than fuzzy sets. The book discusses some of the IFS extensions (for example, interval-valued IFSs, temporal IFSs and others) and applications (e.g. intuitionistic fuzzy expert systems, intuitionistic fuzzy neural networks, intuitionistic fuzzy systems, intuitionistic fuzzy generalized nets, and other).
