Cooperation Model Based On Multi-Agent Integration Of Medical Information

Because lack of effective sharing and a unified standard in the health care information systems, islands of information appear between the departments of information systems and the various medical institutions.The traditional component-oriented methods lack of inflexible interaction, but the society, intelligence, initiative and other features of multi-Agent can make the heterogeneous and dynamic systems integration to be resolved in the process of information integration.Firstly, this article discusses the basic theory and multi-Agent Collaboration, focusing on multi-Agent communication mechanism and multi-Agent Collaboration based on contract net protocol.The contract net is a protocol which used for communication and collaboration of each Agent on the distributed problem solving environment, each Agent within the knowledge, skills and strategies is always dynamic in the problem solving process, so the traditional contract net is not strong practical implementation and is difficult to construct. This paper analyzes the shortcomings of the traditional classical contract net and improved them, proposed combination of contract net and acquaintances collaboration model, using the acquaintance model for a reasonable selection in the early bidding.Perceptual characteristics of the Agent can improve the passive of the task Agent when it accepts tasks. Introduced trust, proactive perception characteristic and active parameters in the bidding process can prevent the selfishness of the bidders, balance the load of all contract holders. Finally, the Agent model is applied in the medical information integration system, analysis the operation mode of medical institutions use the Agent-oriented analysis method. Combined the Agent model's proactive perception characteristic, contract net and acquaintances, designed the system communication module, collaborative model and the system database in detail, analyzed system efficiency and system load. The result proves that this integration strategy can solve islands problems which exist in the current medical institutions. The improved contract net reduces network traffic and improves the collaboration efficiency of multi-Agent system.
