Need for Decision Support Systems

When facing complex multi-criteria decision problems, there is a need to support decision-makers. In this chapter we outline several computer-based decision support systems, which heavily use computer-graphics. At the time they each represented state-of-the-art technology. We describe the VICO system based on harmonious houses, and the VIMDA system based on line graphs. Both systems support decisions, where we can list all alternatives. The third system, which we describe, is called VIG. It is targeted for supporting decision-making in Multiple Objective Linear Programming environments, where the alternatives are implicitly defined via constraints.
