International Workshop on Intuitionistic Fuzzy Sets

International Workshop on Intuitionistic Fuzzy Sets is a scientific meeting devoted to the intuitionistic fuzzy sets, held in Banska Bystrica, Slovakia annually since 2005 year. It is organized on the basis of a bilateral agreement for scientific cooperation between the Department of Mathematics in the Matej Bel University and the Institute of Biophysics and Biomedical Engineering at the Bulgarian Academy of Sciences.

The papers, presented at the workshop, are published in the journal "Notes on Intuitionistic Fuzzy Sets".
