Objective To build a regional cooperative healthcare system in order to make the best use of the limited medical resources,reduce the cost,and improve the quality of medical treatment.Methods Data warehouse and virtual database were used to build regional data center and realize data integration of hospital information system.Upon this foundation,a web service integration of hospital information system based on SOA was realized.Results This design scheme realized the effective management and integration of huge information resources,and managed the medical workflow effectively.Conclusion This design scheme provides the regional cooperative healthcare system with the characteristics of modularization and expansibility.Hierarchy architecture enhances the stability of the system.

Objective To improve the organization and management of the hospital,optimize the medical processes,improve medical quality and reduce medical costs.Methods A method of using multi-agent technology to hospital complex system modeling and simulation was introduced.The theory of complex system and its modeling method were simply introduced and the complex system characteristic and the medical processes of hospital were analyzed.Results The technology and fundation of multi-agent modeling were summarized.The steps of modeling and simulation for complex system of hospital were presented.The swarm simulation platform and the detail design of agent model in hospital were also presented.Conclusion It is proposed that the simulation research of hospital should use the methodology of multi-agent-based modeling and simulation,which is the research method of complex system.
