Rough multisets and information multisystems (Q764788)

Summary: Rough set theory uses the concept of upper and lower approximations to encapsulate inherent inconsistency in real-world objects. Information multisystems are represented using multisets instead of crisp sets. This paper begins with an overview of recent works on multisets and rough sets. Rough multisets are introduced in terms of lower and upper approximations. The paper concludes with an example of certain types of information multisystems.
