The Journal of Fuzzy Extension & Applications (JFEA) is currently accepting manuscripts for publication in English. JFEA is a peer-reviewed journal that publishes high-quality original papers in the theory, design, and applications of Fuzzy sets and their generalization such as “Intuitionistic fuzzy sets”, “Pythagorean fuzzy sets”, “picture fuzzy sets”, “Hesitant fuzzy sets”, ”Neutrosophic sets”, “Plithogenic set”, ”Hypersoft set”, etc. Contributions may consist of invited tutorials or critical reviews, original scientific and innovative research papers (regular papers), reviews, and short papers that should also be original and presenting proposals for a new research, reporting on research in progress or discussing the latest scientific results in advanced fields. JFEA is published quarterly with fast editorial process. Our objective is to inform authors of the decision on their manuscript within two months of submission. Following acceptance, a paper will be published in the next available volumes of the journal. JFEA is committed to the Open Access Initiative and will provide free access to all research articles as soon as they are published. Open access gives a worldwide audience larger than that of any subscription-based journal and thus increases the visibility and impact of published works, and enhances indexing, retrieval power and eliminates the need for permissions to reproduce and distribute content. On behalf of Steering Committee & Advisory Board we cordially invite you to support this initiative by your submissions to the journal. Potential authors should submit their manuscript(s) via the online submission system.

The journal considers papers that have not been published previously nor submitted simultaneously to elsewhere at any languages. The copyright form will be provided by publisher for the accepted papers. The journal accepts four types of papers in English language for review consideration as follows:

  1- Research paper: A regular paper which proposes a new finding via a research procedure.

  2- Review paper: A paper which aims to present comprehensively already existing findings.

  3- Innovative paper: A paper which aims to present new procedures or devices.

  4- Short paper: A pa per which provides a new method in scientific area or introduces a new theory.
