Intuitionistic fuzzy sets (IFSs) are essential in the multi-criteria decision making (MCDM)
under uncertain environment. However, how to reasonably aggregate them with considering …

The q-rung orthopair fuzzy graph is an extension of intuitionistic fuzzy graph and
Pythagorean fuzzy graph. In this paper, the degree and total degree of a vertex in q-rung …

A q-rung orthopair fuzzy model is a powerful framework for illustrating uncertainty and
vagueness. This model is more practical, flexible and appropriate as compared to fuzzy …

The recently proposed q-rung orthopair fuzzy sets (q-ROFSs) have great powerfulness and
