Fuzzy sets (FSs), rough sets (RSs), quantales, and core successor classes (CSCs) are mathematical tools that are applicable in real-world situations with imprecise and ambiguous data. In this research, we propose the novel idea of RSs on -algebra in quantales that are based on CSCs under fuzzy relations (FRs). The following article contains a notion that has never been introduced before. This merges the -algebras and RSs in quantales to provide a new approach for reducing uncertainty in various fields. We develop a mathematical model for approximate substructures on -algebras via CSCs, based on which options can be evaluated in a situation where the information is imprecise. The proposed approach is a recommended technique for coping with ambiguity and uncertainty in multiple fields. Applications in different fields are described, and theoretical foundations of rough -algebras are explored. Our findings demonstrate the effectiveness of the suggested strategy in handling ambiguity.
