In this paper, we extend the Hamy mean (HM) operator and dual Hamy mean (DHM)
operator with Pythagorean fuzzy numbers (PFNs) to propose Pythagorean fuzzy Hamy …

Pythagorean fuzzy set (PFS), disposing the indeterminacy portrayed by membership and
non-membership, is a more viable and effective means to seize indeterminacy. Due to the …

Hesitant Pythagorean fuzzy (HPF) sets can easily express the uncertain information while
Maclaurin symmetric mean (MSM) operator, can capture the interrelationship among the …

The q-rung orthopair fuzzy sets (q-ROFSs), originated by Yager, are good tools to describe
fuzziness in human cognitive processes. The basic elements of q-ROFSs are q-rung …

The cosine similarity measure has been widely studied under different information
environments. Generally, average cosine similarity values are used to find the degree of …

Hamacher product is at‐norm and Hamacher sum is at‐conorm. They are good alternatives
to algebraic product and algebraic sum, respectively. Nevertheless, it seems that most of the …

In this paper, we expand the Hamy mean (HM) operator and Dombi operations with interval-
valued intuitionistic fuzzy numbers (IVIFNs) to propose the interval-valued intuitionistic fuzzy …

In this article, we combine the original VIKOR model with a triangular fuzzy neutrosophic set
to propose the triangular fuzzy neutrosophic VIKOR method. In the extended method, we …

In this article, we expand the original TODIM (Portuguese acronym for Interactive Multi-
Criteria Decision Making) method to the 2-tuple linguistic Pythagorean fuzzy environment to …

The Pythagorean fuzzy set (PFS) is characterized by two functions expressing the degree of
membership and the degree of nonmembership, which square sum of them is equal or less …
