Building Spatial Decision Support Tools for Individuals and Groups

ABSTRACT: We conducted a series of experiments on collective multiple criteria decision making in a spatial context. The first experiment allowed us to understand the needs of participants and facilitator (mediator) of the decision making process. This gave us the design basis for developing a set of interactive software tools to support decision making by individuals and groups. The tools were tested and evaluated by users in the subsequent experiments. The results of the experiments demonstrated that a variety of computational and visual tools is needed to support different decision making styles
