'''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.

			== <font color="#D33682">IMPORTANT ANNOUNCEMENT: Temporary suspension of new submissions</font> ==

			'''Effective 1 June 2026, Notes on Intuitionistic Fuzzy Sets (NIFS) will temporarily suspend new manuscript submissions for a period of three months.'''

			In recent months, the number of submitted manuscripts has grown significantly, creating a workload that exceeds the current capacity of our dedicated team of volunteer editors and peer reviewers. High-quality peer review—an essential element of our Journal’s integrity—requires time, care, and the availability of qualified experts. To safeguard the rigor and quality of our editorial process and maintain our status of a non-commercial, academic-owned journal, we have chosen to pause new submissions while we focus on the thorough review and production of manuscripts already under consideration.

			'''We anticipate reopening for new submissions on 1 September 2026.'''

			Our entire archive of published articles remains freely accessible in the interest of open and equitable access to knowledge.

			We sincerely thank all our authors for their understanding and patience, and we extend our deepest gratitude to our Editorial Board members and volunteer reviewers for their expertise, commitment, and invaluable contributions to the advancement of mathematical research.

			Papers will only be considered if the content is substantially new, original material which has not been published elsewhere, has not been submitted concurrently elsewhere, nor is likely to be published substantially in the same form elsewhere. NNTDM reserves the right to conduct a preliminary screening (triage) of the manuscripts and desk reject without further peer review any submissions that are out of the thematic scope of the Journal, not formatted in accordance with the Journal’s templates and requirements, or feature content below the level of a scientific journal.

			Authors are welcome to suggest two or three names of potential reviewers with their Scopus profiles and email addresses. Please note that these potential reviewers shall not share the same affiliation and country of residence with any of the coauthors of the submitted manuscript. Further, a Scopus h-index of at least 5 is required. However, NNTDM reserves the right to invite for reviewers other specialists than those proposed.
