基于Agent的Web服务集成模型与集成算法

摘要

针对现有Web服务集成方法在动态性、灵活性和智能性等方面存在的不足,提出一种基于Agent的Web服务集成模型,对模型中多Agent系统的组织结构和交互方式进行了设计.为实现集成服务整体的QoS目标,以一个通用的Web服务QoS度量模型为基础,将局部最优与全局最优的思想相结合,提出一种基于QoS的Web服务集成路径选择算法,通过实验验证了其有效性.%In order to improve the deficiency of existing Web service integration methods,this paper proposes an agent-based web service integration model and designs the organization structure and communicating pattern of the multi-agents system in this model.Morcover,a general QoS model is established to realize the predetermined objective under the constraint of the QoS of composite services.Finally,combining the local optimization and the overall optimization,this paper constructs the QoS-based algo-rithm of selecting Web service integration path and checks out its effectiveness through the experiment.
