Abstract

This paper deals with a technique of tradeoff analysis in multiobjective systems. For this purpose a technique called IPSM (Interpretive Preference Structual Modeling) is proposed. It is obtained as an application of Warfield's ISM (Interpretive Structural Modeling) to our problem. In IPSM we analyze a decision-maker's preference relations among many Pareto-optimal solutions of the multiobjective systems under the interactive cooperation between the decisionmaker and the model-builder (computer), and extract the decision-maker's preference structure as a hierarchical directed-graph where the vertices of the graph correspond to the Pareto-optimal solutions and the directed edges correspond to the preference relations. To show the effectiveness of the approach in this paper a numerical example of consumption-pollution problem is included.
