The goal of the Journal of Fuzzy Extension and Applications (JFEA) is to help promote the advances in the development and practice of fuzzy sets and their generalization in the areas of foundations, mathematics, finance, management, economic, data analysis, decision support system, numerical methods, information systems, artificial intelligence, uncertainty and indeterminacy modeling, soft computing, granular computing, and others. The scope of the journal involves fuzzy sets extensions and applications in every branch of science and technology.
Specific topics of JFEA include, but are not limited to:
