In this paper, the authors proposed a new replica selection strategy which uses grey based rough set clustering algorithm to cluster replicas into classes and use classes' labels as decision attributes in case they are unavailable by replica manager. Grey numbers help in compilation number of sites which values are close together in one group grey category. They used rule algorithm to formulate the efficient rules which are used to minimize the searching space. To select the best replica site, the result shows that their proposed approach RSCDG is faster than the previous method.
