摘　　要：随着面向服务架构(SOA)的开发技术不断成熟,Internet上涌现出功能相同或相似的Web服务集合越来越大,如何从这些集合中选出满足用户质量(QoS)的组合Web服务是目前国内外学者研究的热点问题。针对保证组合服务的质量(QoS)全局最优问题,基于图的理论构建服务组合模型,并在此模型上提出相应的服务选择算法,保障选择的组合服务的质量(QoS)全局最优。With the maturity of Web service technology,the same or similar functional Web services collection becomes increasing large.How to select the Web service composition satisfiable to users’ QoS from the Web services collections is a hotspot for domestic and overseas scholars.According to the globally optimized QoS in guaranteeing the service composition,and based on theoretical model of the graph,the Web service composition model is constructed,and the service selection algorithm is proposed for guaranteeing the globally-optimized quality of the selected service composition.
