We consider the problem of multi-agent group decision making. We describe the possible use of the uninorm aggregation operator as a way of combining individual agents' preference functions to obtain a group preference function. We then discuss the possibility of an agent using a type of strategic manipulation of the preference information it provides in order to get the group to select its most preferred alternative. A mechanism is then suggested for modifying the construction of the group decision function to defend against this type of strategic manipulation. In addition to considering the case where the preference information is provided numerically we consider the case of ordinal preference information. (C) 2002 Elsevier Science B.V.
