Some results on certain properties of intuitionistic fuzzy sets

Jaydip Bhattacharya

Volume 2, Issue 4 , December 2021, , Pages 377-387

https://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

Volume 2, Issue 3 , September 2021, , Pages 239-261

https://doi.org/10.22105/jfea.2021.306164.1162

Abstract
  In this paper we extend the notion of interval representation for interval-valued Atanassov’s intuitionistic representations, in short Lx-representations, and use this notion to obtain the best possible one, of the Weighted Average (WA) and Ordered Weighted Average (OWA) operators. A main characteristic ...  Read More
