Applying Normative Multiagent Systems

We present a conceptual model of control mechanisms for virtual organizations. Control mechanisms and norms in general have certain objectives. We propose to model both the participants, and the normative system itself as autonomous agents, having certain beliefs, desires and goals. Norms, which can be internalized by the agents as obligations, are translated into conditional beliefs, desires and goals of the normative system, which concern both detection and sanctioning measures. The model is illustrated by a case study of the Renewable Obligation Certificates (ROC), introduced in the United Kingdom to stimulate the production of renewable energy. We show that the model can handle both the regulative and the evidential aspects of the case.
