Besma Belhadj

Volume 3, Issue 4 , October 2022, Pages 279-289

https://doi.org/10.22105/jfea.2022.345298.1222

Abstract
  Under the additional assumption that the errors are normally distributed, the Ordinary Least Squares (OLS) method is the maximum likelihood estimator. In this paper, we propose, for a simple regression, an estimation method alternative to the OLS method based on a so-called Gaussian membership function, ...  Read More

Soft set product extended to hypersoft set and indetermsoft set cartesian product extended to indetermhypersoft set

Florentin Smarandache

Volume 3, Issue 4 , October 2022, Pages 313-316

https://doi.org/10.22105/jfea.2022.363269.1232

Abstract
  In this paper we define the Soft Set Product as a product of many soft sets and afterwards we extend it to the HyperSoft Set. Similarly, the IndetermSoft Product is extended to the IndetermHyperSoft Set. We also present several applications of the Soft Set Product to Fuzzy (and fuzzy-extensions)  ...  Read More

Research Paper Hesitant fuzzy sets and their variants
Supply chain management problem modelling in hesitant fuzzy environment

Madineh Farnam; Majid Darehmiraki

Volume 3, Issue 4 , October 2022, Pages 317-336

https://doi.org/10.22105/jfea.2022.337573.1216

Abstract
  Complex nature of the current market is often caused by uncertainties, data uncertainties, their manner of use, and differences in managers' viewpoints. To overcome these problems, Hesitant Fuzzy Sets (HFSs) can be useful as the extension of fuzzy set theory, in which the degree of membership of an element ...  Read More

Basic fuzzy arithmetic operations using α–cut for the gaussian membership function

Leonce Leandry; Innocent Sosoma; David Koloseni

Volume 3, Issue 4 , October 2022, Pages 337-348

https://doi.org/10.22105/jfea.2022.339888.1218

Abstract
  Currently fuzzy set theory has a wide range to model real life problems with incomplete or vague information which perfectly suits the reality and its application is theatrically increasing. This work explored the basic fuzzy operations with the Gaussian Membership using the α-cut method. As it ...  Read More

Research Paper Picture fuzzy sets and their variants
Some picture fuzzy mean operators and their applications in decision-making

Hasan Mohammad Kamrul; Ali Md. Yasin; Sultana Abeda; Mitra Nirmal Kanti

Volume 3, Issue 4 , October 2022, Pages 349-361

https://doi.org/10.22105/jfea.2022.341302.1219

Abstract
  Picture fuzzy set is the generalization of fuzzy set and intuitionistic fuzzy set. It is useful for handling uncertainty by considering the positive membership, neutral membership and negative membership degrees independently for each element of a universal set. The main objective of this article is ...  Read More
