In this paper we introduce an interactive, display-oriented postprocessor for multiobjective selection or discrete optimization, which has been implemented within the framework of a project on Advanced Decision-Oriented Software for the Management of Hazardous Substances. The approach and software described here is designed as a tool to improve the usefulness and usability of decision support systems through the easy access to a rich set of powerful support functions and display options, and tight integration with substantive models and data bases. At the same time it adds a new dimension of usefulness to the simulation models it is connected to as an output post-processor, aiding in the comparative evaluation of complex modeling results
