A novel decision-making approach based on sine trigonometric cubic Pythagorean fuzzy aggregation operators

Abstract The objective of this study is to imitate several efficient sine-trigonometric operational laws to handle the decision-making process under the cubic Pythagorean fuzzy set environment. The sine-trigonometric function provides the periodicity and symmetry of the origin in nature and satisfies the potentials of decision-makers over the considerations of the decision-making process. keeping the advantages of the sine function and the significance of the cubic Pythagorean fuzzy set, we demonstrate the novel sine trigonometric operational laws under the cubic Pythagorean fuzzy environment. Based on these operational laws, novel sine trigonometric cubic Pythagorean fuzzy aggregation operators are developed. This study mainly focuses on a decision-making approach for multi-criteria decision-making problems that is based on proposed aggregation operators with given weight information of the criterion. Lastly, to demonstrate the efficiency, an illustration is presented. Sensitivity and comparison analyses are used to evaluate the method’s permanency and rationality.
