Normative Agent Social

It is a challenging problem to ensure the global goal of virtual organization together with maintaining the autonomous ability of individual agent in open, dynamic and heterogeneous network environment. Aiming at this problem, this paper proposes a model of agent social based on norms, policies, and contracts to form and operate VO. This model is divided into three layers: macro regulation layer, micro behavior layer, and joint layer. Firstly, in macro regulation layer, we design e-institution and its social behavior norms to regulate the cooperation behavior of autonomous agent. Secondly, in micro behavior layer, we design policy-driven agent which can accept the regulation from macro regulation layer. Finally, the joint layer joins the two layers to make the whole system operable. Thus, the cooperation behavior of autonomous agents can achieve the global goal of VO.
