Abstract:
In this work, a hybrid multicriteria decision making (MCDM) model utilizing the Cubic Bipolar Pythagorean Fuzzy Sets (CBPFSs) in the R-order has been presented. Interior, Exterior, Frontier, and Basis have been introduced to construct a topological structure. Entropy is used to calculate the objective criteria weights, then VIKOR and COPRAS methods are adopted for ranking of alternatives. The proposed methodology is illustrated via a real-world problem related to selection of the best alternative for cancer treatment.
