Notes on Intuitionistic Fuzzy Sets is an international scientific journal, specialized in the theory and application of intuitionistic fuzzy sets and logics as an interdisciplinary field at the cross point between mathematics and engineering sciences.

Scope

Having started in 1995, Notes on Intuitionistic Fuzzy Sets is the first and one of the leading scientific journals, exclusively publishing research in this field of science, as defined by the strict journal's scope and Editorial policy. Created in 1983 in Bulgaria by Prof. Krassimir Atanassov, the area of intuitionistic fuzzy sets has gained worldwide popularity and today it is being investigated by many international research groups from universities and research centres in Australia, Belgium, China, Greece, India, Morocco, Poland, Portugal, Romania, Slovakia, Spain, Turkey, United Kingdom, and other countries.

The journal is one of the three official issues of the Institute of Biophysics and Biomedical Engineering of the Bulgarian Academy of Sciences (see http://biomed.bas.bg/bg/journals/). It is published by the "Prof. Marin Drinov" Publishing House of Bulgarian Academy of Sciences under Print ISSN 1310-4926, e-ISSN 2367-8283 and DOI 10.7546/nifs (as of 2018).

Since 1997, the Journal has been hosting the proceedings of the International Conference on Intuitionistic Fuzzy Sets, organized on annual basis in Sofia or Burgas, Bulgaria. Since 2005, it has also included the proceedings of the International Workshop on Intuitionistic Fuzzy Sets, annually conducted in Banská Bystrica, Slovakia.
