It plays a significant role in the mainstream of decision science. Its main process is to rearrange available choices and select the optimal option out of a group of options based on certain characteristics assigned by the decision maker. Aggregation operators (AOs) play a significant role in MADM techniques to aggregate uncertain and vague information. Aczel Alsina aggregation models are recently introduced to handle ambiguous and dubious information, Aczel Alsina aggregation models attained a lot of attention from numerous research scholars. This article aims is to generalize the concept of pythagorean fuzzy sets (PyFSs) in the framework of interval-valued pythagorean fuzzy (IVPyF) sets (IVPyFSs) by utilizing the basic operations of Aczel-Alsina aggregation …
