The Journal of Fuzzy Extension and Applications (JFEA) is an international, interdisciplinary, open-access journal that has been fully refereed and free of charge since 2020. It provides a platform for original research articles on the theory, design, and applications of fuzzy sets and their extensions, such as Intuitionistic, Pythagorean, Picture, and Hesitant fuzzy sets, as well as Neutrosophic, Plithogenic, and Hypersoft sets, among others. JFEA aims to promote the advances in developing and practicing fuzzy sets and their generalization in various fields, including foundations, mathematics, artificial intelligence, finance, management, economics, uncertainty and indeterminacy modeling, information systems, soft computing, and more. The journal's scope involves fuzzy set extensions and applications in every branch of science and technology. JFEA is committed to following the executive regulations of the COPE. Additionally, JFEA has a memorandum of understanding with the Neutrosophic Science International Association (NSIA). See more details
