摘要
随着Web服务架构在企业信息化中应用的普及,针对Web服务的服务质量(QoS)需求,提出了多Agent协作机制下保障QoS的服务决策系统;通过对传统的Web服务架构的研究,扩展了UDDI注册中心,使其能够实现QoS属性的描述、发布、查询和更新;在此基础上加入了用户Agent、服务商Agent和决策Agent,在多Agent协助和交互的机制下,给出主客观赋权排序的群决策算法;算法综合考虑了QoS的主观需求和客观条件,使系统实现保障QoS的服务决策。
With the universal application of Web services in the construction of enterprise information, a QoS-guaranteed system for selecting web service based on multi-agent was proposed for the QoS requirement of Web service. Through the research of the traditional framework of Web serv- ices, expanding the UDDI registration centre is in order to achieving the description, publish, query and update of QoS attributes. In addition, using user agent, service provider agent and decision-making agent and introducing the group decision-making algorithm which considered subjective needs and objective conditions of the QoS allow the system to achieve QoS-guaranteed decision-making.
