Abstract :
In this paper, a novel grey rough set model for interval-valued grey sets information systems named interval-valued grey-rough set model is proposed and the basic theory and propositions of the interval-valued grey-rough sets is studied. Based on the proposed interval-valued rough grey model, rough similarity degree is defined, and the clustering of the interval-valued grey information systems is also examined, in the meanwhile, some examples are presented respectively.
