Spatial Discourses in Participatory Decision Making

We report from a role-playing experiment concerned with spatial decision-making in groups. We combined methods from classical mediation with software for web-based discourses (Zeno) and multi-criteria spatial exploration (CommonGIS). The lessons learned concern the integration of the tools, a model of decision tasks in facility allocation, a corresponding template for structuring discourses in Zeno, and the organization of the process as an alternation of face-to-face meetings with web-based communication.
