Abstract
<p>The essential aim of the current work is to enhance the application aspects of Pawlak rough sets. Using the notion of a <italic>j</italic>-neighborhood space and the related concept of <italic>θβ</italic>-open sets, different methods for generalizing Pawlak rough sets are proposed and their characteristics will be examined. Moreover, in the context of ideal notion, novel generalizations of Pawlak's models and some of their generalizations are presented. Comparisons between the suggested methods and the previous approximations are calculated. Finally, an application from real-life problems is proposed to explain the importance of our decision-making methods.</p>
