Fuzziness of Covering Generalized Rough Sets
Wen‐Xiu Zhang · Mohu xitong yu shuxue · 2006
Rough set theory has been considered as a useful mean to model the vagueness and has been applied successfully in many fields. And every rough set is associated with some amount of fuzziness. Some measure of fuzziness in rough sets has been provided. On the other hand, rough set theory has been generalized with coverings instead of classical partition. So it is necessary to consider the amount of fuzziness in covering generalized rough sets. The main aim of the paper is to study the problem. A measure of fuzziness in covering generalized rough sets is proposed in this paper. Moreover, some characterization and properties of this measure are achieved with examples, which is every useful for next research works in covering generalized rough sets.
