Abstract
Previously developed decision support systems for multiattribute evaluation focus on support of computation and representation, but provide no guidance for efficient use of methods for particular decision problems and environments. We examine a procedural support strategy to guide the decision maker in efficiently choosing what judgments to consider in the computation of equivalent alternatives (CEA) method. A Monte-Carlo simulation measures the efficiency and accuracy of various procedural strategies. Decision rules are identified that can structure CEA and enhance its efficiency. The implied combination of procedural expertise and substantive domain expertise will help to create more effective decision support systems.
