In this article, we introduce the 2-tuple linguistic bipolar fuzzy set (2TLBFS), a new strategy
for dealing with uncertainty that incorporates a 2-tuple linguistic term into bipolar fuzzy set …

In this paper, we expand the generalised Heronian mean (GHM) operator, generalised
weighted Heronian mean (GWHM), geometric Heronian mean (GHM) operator, and …

Renewable energy sources play an influential role in the world's climate and reduce the rate
of harmful gasses such as carbon dioxide, methane, nitrous oxide, and many other …

In this paper, a new extension of linguistic term sets called Pythagorean uncertain linguistic
sets (PULSs) is defined, which is based on uncertain linguistic term sets and Pythagorean …

In this manuscript, we combine the notion of linear Diophantine fuzzy set (LDFS), uncertain
linguistic set (ULS), and complex fuzzy set (CFS) to elaborate the notion of complex linear …

In recent years, the environmental problems in China have become more and more serious,
for example, resource depletion, environmental pollution, ecological imbalance, and so on …

As a new improvement of fuzzy sets (FSs), spherical fuzzy sets (SFSs) can provide a wider
space for decision-makers (DMs) to express their preference information. Spherical fuzzy …

In this paper, we investigate the multiple attribute decision making (MADM) problems with 2-
tuple linguistic information. Motivated by the ideal of Bonferroni mean and geometric …

Complex T-spherical fuzzy 2-tuple linguistic set (CTSF2-TLS), which is a combination of
complex fuzzy set (CFS), T-spherical fuzzy set (TSFS), and 2-tulpe linguistic variable set (2 …

On the basis of Hamacher operations, in this manuscript, we interpret bipolar complex fuzzy
Hamacher weighted average (BCFHWA) operator, bipolar complex fuzzy Hamacher ordered …
