A novel multiple‐attribute group decision‐making method based on q‐rung orthopair fuzzy generalized power weighted aggregation operators

In this paper, a novel approach is developed to deal with multiple‐attribute group decision‐making (MAGDM) problem under q‐rung orthopair fuzzy environment. Firstly, some operators have been proposed to aggregate q‐rung orthopair fuzzy information, such as the q‐rung orthopair fuzzy generalized power averaging (q‐ROFGPA) operator, the q‐rung orthopair fuzzy generalized power weighted averaging (q‐ROFGPWA) operator, the q‐rung orthopair fuzzy generalized power geometric (q‐ROFGPG) operator, and the q‐rung orthopair fuzzy generalized power weighted geometric (q‐ROFGPWG) operator. In addition, some desirable properties and special cases of these operators are discussed. Second, a novel approach is developed to solve MAGDM problem under the q‐rung orthopair fuzzy environment based on the proposed q‐ROFGPWA and q‐ROFGPWG operators. Finally, a practical example is given to illustrate the application of the proposed method, and further the sensitivity analysis and comparative analysis are carried out.
