Case study for hospital-based Post-Acute Care-Cerebrovascular Disease using Sine Hyperbolic q-rung orthopair fuzzy Dombi aggregation operators

Abstract

The Sine Hyperbolic q-rung orthopair fuzzy sets (sinh-q-ROFSs) are the important concept of accepting more uncertainty than the q-rung orthopair fuzzy sets (q-ROFSs). The well-known sine hyperbolic function preserves the origin’s periodicity and symmetric existence, and so fulfills the expert’s expectations for the multi-time process’ parameters. The aim of this study is to offer some robust sine hyperbolic Dombi operation laws (sinhDOLs) for q-ROFSs in order to preserve these qualities and the significance of sinh-q-ROFSs. Score and accuracy functions for the sinh-q-ROFSs’ are also defined. We define a number of new averaging/geometric aggregation operators (AOs) based on Dombi t-norm and conorm operations. The fundamental properties of the defined operators were discussed. Then, using defined AOs, we provide a group decision-making (DM) approach for solving DM problems. We demonstrate a numerical example to verify the defined method.
