Circular q-Rung Orthopair Fuzzy Set and Its Algebraic Properties

Abstract

Circular intuitionistic fuzzy sets (CIFS) are a recent extension of intuitionistic fuzzy sets (IFS) that can handle imprecise membership values effectively. However, its representation is limited to the space under the intuitionistic fuzzy interpretation triangle (IFIT). To address this, a new generalization of CIFS called circular q-rung orthopair fuzzy sets (Cq-ROFS) is proposed, extending the IFIT to cover a larger space of imprecision. Several relations and operations, including algebraic operations for Cq-ROFS are proposed. In addition, modal operators and their properties are then investigated.

“…Moreover, El-Gayar et al [18]'s research on economic decision-making employing rough topological structures , has expanded our comprehension of economic applications. In addition, Yusoff et al [34]'s study on the circular q-rung orthopair fuzzy set and its algebraic properties contributes to further advance-ments in this field.…”
