Title of paper: On interval-valued intuitionistic fuzzy modal operators Author(s): Krassimir Atanassov Department of Bioinformatics and Mathematical Modelling, Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, Acad. G. Bonchev Str., Bl. 105, Sofia-1113, Bulgaria Intelligent Systems Laboratory, Prof. Asen Zlatarov University, Bourgas-8010, Bulgaria krat@bas.bg Published in: Notes on Intuitionistic Fuzzy Sets, Volume 24, 2018, Number 1, pages 1—12 Download:  PDF (174 Kb  Kb, File info) Abstract: An survey of the existing interval-valued intuitionistic fuzzy modal operators is given. Eight new operators are introduced that extend the older ones. Some of their basic properties are discussed. Open problems are formulated.
