This work presents an adaptive sanctioning mechanism that can be applied in open multi-agent systems that are regulated through norms. This mechanism tries to identify the attributes of the environment that have some influence on agents decision making and uses such attributes to define sanctions that may prevent norm violations. Our approach adapts sanctions to particular agents and particular environmental...
In multi-agent system, agents need autonomy and collaboration to accomplish a complex task. Contract net protocol (CNP) is coordination mechanism often used in a multi-agent system. Due to the limitations inherent in the conventional CNP, this paper proposes a Norm-based CNP to improve the efficiency and effectiveness of the coordination processes in a multi-agent system. First, a three-dimensional...
One of the main problems of normative system implementation is the semantic gap between the abstract norms described by natural language and the concrete norms described by operational language. This paper introduced an autonomous layered normative system framework which divided the normative system into three different layers. In this framework we realized automatic norm refinement by setting up...
In order to enable the individual agents to be aware of the both macro constraints from agent social and instructions from agent's owner, a norm and policy extended agent BDI model (called NPCD-Agent) has been proposed, by integrating norms and policies into traditional agent BDI model. On the basis of NPCD-Agent model, this paper proposes a semantic model of multi-agent system (called MASNP), where...
