AN EXTENDED MODEL FOR ESTABLISHING DOMINANCE IN MULTIATTRIBUTE DECISION-MAKING

This paper is concerned with the use of incomplete information about u tilities and weights in multiattribute decisionmaking. Because of time pressure and/or lack of knowledge, a decision maker may only be able to provide incomplete information which might be expressed as a set of linear inequalities. If the decision maker's information on both weig hts and utilities is imprecisely identified, then the model for establ ishing pairwise dominance becomes a non-linear program. A method for o btaining non-dominated alternatives without solving the non-linear pro gram is proposed using a simple weighted-additive function.
