The aim of this paper is to present a new model of decision support system for group decision making\udproblems based on a linguistic approach and dynamic sets of alternatives. The model incorporates a\udmechanism that allows to manage dynamic decision situations in which some information about the\udproblem is not constant in time. We assume that the set of alternatives can change during the decision\udmaking process. The model is presented in a mobile and dynamic context where the experts preferences\udcan be incomplete. The linguistic approach is used to represent both the experts preferences about\udthe alternatives and the agreement degrees to manage the change of some alternatives. A prototype of\udsuch mobile decision support system in which the experts use mobile devices to provide their linguistic\udpreferences at anytime and anywhere has been implemented. In such a way, we provide a new linguistic\udgroup decision making framework that is mobile and dynamic.
