Developments of this study.

Development	Reasons
Development of complex Pythagorean fuzzy rough structure	To cover the chance of data loss as it exists in the existing notion of complex intuitionistic fuzzy rough set
Development of Yager’s operational laws for complex Pythagorean fuzzy rough numbers	These developed operational rules can help us define the aggregation theory.
Development of complex Pythagorean fuzzy rough Yager weighted average and geometric AOs	These AOs can cover more advanced data and provide more space for decision-makers.
Development of the WASPAS approach	The WASPAS can combine the weighted sum model and the weighted product model and this method can be used in MCDM approaches.
Development of comparative analysis	The comparative analysis of the initiated approach can help to discuss the advantages of the initiated work.
