Articles in Press, Accepted Manuscript, Available Online from 27 March 2021

http://dx.doi.org/10.22105/jfea.2021.275094.1081

Abstract
  The Ordered Weighted Averaging (OWA) operator was introduced by R.R. Yager [58] to provide a method for aggregating inputs that lie between the max and min operators. In this article several variants of the generalizations of the fuzzy-probabilistic OWA operator - POWA (introduced by J.M. Merigo [27,28]) ...  Read More

3. A Neutrosophic Student’s t –Type of Statistic for AR(1) Random Processes

Athanase Polymenis

Articles in Press, Accepted Manuscript, Available Online from 12 June 2021

http://dx.doi.org/10.22105/jfea.2021.287294.1149

Abstract
  Neutrosophic statistics are used when one is dealing with imprecise and indeterminate data or parameters. In the present paper we propose a method for performing a neutrosophic Student’s t –type of statistical test that concerns the population mean when data arise from an autoregressive process ...  Read More

4. An Application of Neutrosophic Logic in the Confirmatory Data Analysis of the Satisfaction with Life Scale

Volkan Duran; Selcuk Topal; Florentin Smarandache

Articles in Press, Accepted Manuscript, Available Online from 15 June 2021

http://dx.doi.org/10.22105/jfea.2021.280497.1100

Abstract
  The main concept of neutrosophy is that any idea has not only a certain degree of truth but also a degree of falsity and indeterminacy in its own right. Although there are many applications of neutrosophy in different disciplines, the incorporation of its logic in education and psychology is rather scarce ...  Read More

6. SPHERICAL FUZZY CROSS ENTROPY FOR MULTIPLE ATTRIBUTE DECISION MAKING PROBLEM

PRINCY R; K Mohana

Articles in Press, Accepted Manuscript, Available Online from 22 June 2021

http://dx.doi.org/10.22105/jfea.2021.281447.1120

Abstract
  In this paper, we investigate the multiple attribute decision making problems with spherical fuzzy information. The advantage of spherical fuzzy set is easily reflecting the ambiguous nature of subjective judgments because the spherical fuzzy sets are suitable for capturing imprecise, uncertain and inconsistent ...  Read More

Articles in Press, Accepted Manuscript, Available Online from 04 August 2021

http://dx.doi.org/10.22105/jfea.2021.293069.1157

Abstract
  A Quadripartitioned Neutrosophic Pythagorean (QNP) set is a powerful general format framework that generalizes the concept of Quadripartitioned Neutrosophic Sets and Neutrosophic Pythagorean Sets. In this paper, we apply the notion of quadripartitioned Neutrosophic Pythagorean sets to Lie algebras. We ...  Read More

Articles in Press, Accepted Manuscript, Available Online from 22 August 2021

http://dx.doi.org/10.22105/jfea.2021.290202.1155

Abstract
  An operator is a special symbol for performing a specific function. Several operators like modal operators, topological operators, level operators, etc. have been defined over intuitionistic fuzzy sets. At the same time, so many operations were introduced and studied. The key objective of this paper ...  Read More
