Web12 de mai. de 2006 · Rough sets, a technique of granular computing, deal with the vagueness and granularity in information systems. They are based on equivalence relations on a set, or equivalently, on a partition on the set. Covering is an extension of a partition and a more feasible concept for coping with incompleteness in information, thus the … WebAbstract. In this paper, six types of optimistic multi-covering rough set models and six types of pessimistic multi-covering rough set models are proposed in multi-covering approximation space. From three different points of views, relationships among multi-covering rough set models are deeply investigated.
