Research On Implement Of Muti-agent System Based On Blackboard System

Muti-agent system technology which studies the intelligent behaviors of a group of autonomous agents is a focus in distributed artificial intelligence field presently.Coordination and cooperation is the key issue of the research on the muti-agent system and muti-agent system needed communications among the course of them.Usually communications in muti-agent system adopt a point to point way ,so the course and information of the communication.coordination and cooperation are implicit in the systems .As a result,it is very difficult for us in this case to know what has happened in the system when it is running.In the blackboard system,the knowledge sources communicate indirectly by read and write a public storing region named blackboard and at the same time reading and writing the blackboard is controlled by the controling mechanism. When we regard every agent in the muti-agent system as knowledge source .all of their communications pass through the blackboard and are monitored by the blackboard.As a result,we can eliminate the transparence and enhance the consistency of coordination and cooperation in the system.In this paper.the agent technology.the coordination and cooperation mechanism of muti-agent system,the principle of the blackboard system are introduced and analysed detailedly. On this basis,we propose the concrete scheme to achive muti-agent system's cooperation, coordination,monitoring,and control through blackboard system and we explain and prove that by combining a concrete instance finally. The result shows that we can eliminate transparence and strengthen consistency of muti-agent system effectively if the muti-agent system's communication,coordination and cooperation are implemented by the way of blackboard system.
