TOOLS FOR INTERACTIVE MULTIATTRIBUTE DECISION-MAKING WITH INCOMPLETELY IDENTIFIED INFORMATION

The aim of this paper is to present tools or techniques for an interac tive multiattribute decisionmaking with the decision maker's incomplet e information. That is: (1) We formally describe mathematical models u nder certainty and uncertainty for establishing pairwise dominance, wh ere the incomplete information becomes the set of constraints in the m odel. (2) We present a description on styles of incomplete parameter v alue information. (3) The characteristic of a weak dominance is descri bed. When the decision maker is not willing or able to provide more in formation on parameters, the weak dominance technique is useful for a final choicemaking. (4) We propose a dominance graph and also present an algorithm of generating the dominance graph based on the informatio n of pairwise dominance. The dominance graph compactly displays the do minance structure of all alternatives, thus it can be used for aiding the selection of preferable alternatives.
