A hybrid decision-making analysis under complex q-rung picture fuzzy Einstein averaging operators

This article advances the idea of complex q-rung picture fuzzy set (Cq-RPFS), which is especially an augmentation and a generalization of q-rung picture fuzzy sets (q-RPFSs) by the expansion of phase term in the description of q-RPFSs. The presence of phase term widens the scope of Cq-RPFS from a real plane to complex plane of unit disk and depicts the uniqueness of Cq-RPFS by exhibiting the ability to deal with the ambiguity and periodicity, at the same time. Certain major tasks and properties of Cq-RPFSs are illustrated and examined. Further, the aggregation operators, namely complex q-rung picture fuzzy Einstein averaging operators in Cq-RPFSs environment, based on Einstein operations, weighted and ordered weighted averaging operators are discussed. MCDM problem is solved using these operators and is explained with a numerical example to illustrate the validity and competence of the proposed method. Finally, a comparative study of our proposed technique with existing models is demonstrated to show the superiority and consistency of the model.
