Aim and scope

The aim of the annual International Conference on Intuitionistic Fuzzy Sets (ICIFS) is to gather specialists interested in intuitionistic fuzziness, decision making under uncertainty, and other related topics, and to give them floor for discussions on both the theoretical and practical aspects of intuitionistic fuzzy sets. Since 2013, ICIFS has been an EUSFLAT endorsed event.

Instructions for the Manuscripts and Presentations

All papers accepted for presentation at ICIFS'2024 will be published in the Journal "Notes on Intuitionistic Fuzzy Sets" (ISSN: 1310-4926, e-ISSN: 2367-8283) and will be freely available online under Open Access and with DOI numbers. Papers should not exceed 20 A4 pages and should comply with the paper template of the Journal "Notes on Intuitionistic Fuzzy Sets" and the Journal's Publication Ethics Policy. Manuscripts will be subject to rigorous peer review by two independent reviewers.

Participants who are willing to attend physically in the conference will be recorded and live streamed for those who attend the conference online.

Participants who are willing to attend online are requested to give their talk in real time, but prepare and submit in advance a back-up video of their presentation which will be streamed in case of any technical problems at the time of their presentation.
