This study aims at evaluating new service development (NSD) process of renewable energy
investments. A novel fuzzy hybrid multi-criteria decision-making model is then introduced …

In this paper, we propose a new score function of Fermatean fuzzy numbers (FFNs). The
proposed score function of FFNs can conquer the drawbacks of the existing score function of …

In this paper, we develop a novel multiattribute decision making (MADM) approach based
on Fermatean hesitant fuzzy sets (FHFSs) and the modified VIKOR method. Firstly, we …

With the increasing risk to human health and environmental issues, the selection of
appropriate management and treatment of healthcare waste has become a major problem …

The spherical fuzzy set (SFS), as a generalization of Picture fuzzy set, can express and
process uncertainty much better. In this article, we first reveal the comparison issues in …

Pythagorean fuzzy set (PFS) is a significant soft computing tool for tackling embedded
fuzziness in decision-making. Many computing methods have been studied to facilitate the …

Correlation coefficient (CC) is a reliable information measure for measuring interrelationship
between Pythagorean fuzzy sets (PFSs). Some approaches for calculating CC of PFSs have …

Pythagorean fuzzy set (PFS) is an advanced version of generalized fuzzy sets. It has a better
applicative expression in decision-making because of its capability in curbing fuzziness …

Real-world decision-making challenges tend to evolve into more intricate scenarios over
time. In this context, the Fermatean fuzzy set emerges as an efficient and convenient …

Distance measure under Fermatean fuzzy domain is a soft computing technique for
resolving problems of decision-making where decisions are made based on the closest …
