Another view on q-rung orthopair fuzzy sets

In this paper, two new approaches have been presented to view q-rung orthopair fuzzy sets. In the first approach, these can viewed as L-fuzzy sets, whereas the second approach is based on the notion of orbits. Uncertainty index is the quantity HA(x)=1-(A+(x))q-(A-(x))q, which remains constant for all points in an orbit. Certain operators can be defined in q-ROF sets, which affect HA(x) when applied to some q-ROF sets. Operators I, M,, and K, have been defined. It is studied that how these operators affect HA(x) when applied to some q-ROF set A.
