Rough communication based on general binary relations
(0) The communication between information systems is a basic problem in granular computing. In this paper, the equivalence relations in the information systems were extended to general binary relation. Lower approximation rough communication models based on general binary relations are proposed. The fundamental properties of the new models are investigated. Furthermore, the six composition operators of lower and upper approximation operators form three pairs of dual operators. Based on the three pairs of dual operators, new models of rough cmmunication are constructed. Finally, some good results are proposed compared with the old models.
