Research Of Multi-Agent Intelligent Decision Support System Based On Blackboard

Intelligent Decision Support System(IDSS) is developed based on traditional Decision Support System. With the development of IDSS, when the components of traditional IDSS offer intelligent support, their action are mostly static, passive,it limites the agility and flexibility of assistant intelligence. Thus how to implement the effect cooperation between components so that the information can transfer effectly; uncertainty, inadequate information and imprecision under decision condition, especially distributed decision information on Internet/Intranet, IDSS is faced with new challenge, we need to study farther.First, the development -of IDSS is discussed and some research is done on the Multi-Agent in this paper, such as the definiens, the characteristic and the structure about the agent, Multi-Agent System that is applied in IDSS is particularized. Then presents the concept of a new-style Multi-Agent Intelligent Decision Support Systems Based on Blackboard and design the system model. Each module in the system is described, the structure and function about every Agent is particularized and the formal description is gived. Then the paper gives a brief introduction to the techniques of realization in Agent and the decision process. Moreover, the paper suggests the negotiation algorithm and a method of finding cooperative Agents based on the degree of commitment among decision Agents in the system that united the Multi-Agent harmony principle. And Multi-Agent System based on blackboard is implemented the intelligent decision, proposes the simplest decision tree production algorithm based on rough set and a method based on group's satisfaction degree of alternative for Multi-Attribute group decision-making. The paper suggests that multi-decision Agent implements the sub-assignment under the control and intendance of function Agent, achieves the cooperation and negotiation that uses of blackboard. The traditional blackboard is improved in the paper, the blackboard is controlled by blackboard-controlled Agent, the decomposition of decision assignment, the control of Multi-Agent, combination of sub-assignment and negotiation of conflict are implemented through blackboard-controlled Agent, multi-decision Agent make use of own information to decision together. Then the function of assignment decomposition on blackboard-controlled Agent is formal described.Multi-Agent Intelligent Decision Support Systems Based on Blackboard advances the control of Agent in Multi-Agent System, it adapts to cooperate about cosmically complex assignment. It accords with the development of distribution and intelligence.
