In this paper we present a rough set approach to group decisions making. To deal with decision of multiple decision makers we extend dominance-based rough set by introducing specific concepts related to dominance with respect to minimal profiles of evaluations given by multiple decision makers. Our approach differs from existing group decision approaches for we characterize conditions for a consensus attainable by multiple decision makers considered as a whole. Such a perspective permits to handle interactions between decision makers.
