Abstract
For incomplete information systems, the existing variable multi granularity rough set and weighted multi granularity rough set are extended, and a variable and weighted granularity "logic disjunction" degree multi granularity rough set based on limited tolerance relation is proposed. The properties and relations of variable and weighted granularity "logic disjunction" degree multi granularity rough set, variable degree multi granularity rough set and weighted degree multi granularity rough set are studied. Finally, the effectiveness of the model and related properties is verified by example analysis and experiments.
