In this study, we present a novel notion of an approximation space based on the idea of an ideal,called the rough neighborhood ideal, and its properties. Additionally, we combine two areasin which decision-making precision is improved using rough ideal expansions. An applicationscenario was presented to show how decision-making accuracy increased for COVID-19diagnosis. We also use variable precision to improve the accuracy of decision-making. Finally,we compared our strategy with another strategy.
