An Extended BDI Agent with Policies and Contracts.

In order to enable the intelligent agents to be aware of the dynamic business requirements and strategies, and cooperate with other agents in a stable and explicit way, a policy and contract extended BDI logic (called BGIPDC logic) has been proposed, by integrating contracts and policies into traditional BDI model. On the basis of BGIPDC logic, this paper proposes a model of agent architecture as a concrete realization of it, called PDC-agent. PDC-agent is an extension of traditional BDI agent, by adding a policy engine, a contract engine and a goal maintenance component into agent's interpreter. Besides, PDC-agent has two characteristics. First, the operation of PDC-agent is based on an event-driven mechanism. Various events drive the components of the interpreter. Second, the representation of PDC-agent is on the basis of ontology.
