The concept of complex fuzzy set (CFS) and complex intuitionistic fuzzy set (CIFS) is two
recent developments in the field of fuzzy set (FS) theory. The significance of these concepts …

The assessment of a system's performance is a very important task, enabling its
designer/user to correct its weaknesses and make it more effective. Frequently, in practice, a …

Hypersoft set (HSS) was proposed in 2018 as a generalization of the soft set (SS). In this
paper, the novelty of complex multi-fuzzy hypersoft set (CMFHSS) is discussed, which can …

In this paper, we first generalize the products of two fuzzy soft matrices. Through these
generalizations, three or more fuzzy soft matrices in the different types can be multiplied …

Complex fuzzy set (CFS) is a recent development in the field of fuzzy set (FS) theory. The
significance of CFS lies in the fact that CFS assigned membership grades from a unit circle …

The demand for renewable energy has significantly increased over the last decade with
increased attention to the preservation of the environment and sustainable, optimal resource …

Fighter aircraft selection is one of the most critical strategies for defense multiple criteria
decision-making analysis to increase the decisive power of air defense and its superior …

The various extensions of the fuzzy set are considerably applied in many complex problems
of real world to describes the improper information. The PFS (pythagorean fuzzy set) which …

Fuzzy entropy measures are valuable tools in decision-making when dealing with uncertain
or imprecise information. There exist many entropy measures for Pythagorean Fuzzy Sets …
