摘要:: 组合服务是将一系列Web服务协凋地组合在一起，从而完成预期目标。组合服务按照其引擎分布可分为：集中式服务组合和分布式服务组合。分布式组合服务可以有效地解决集中式组合服务在系统可伸缩性、消息传输效率、自治性和有效负载均衡等方面的问题，将可执行全局流程等价分解成可执行本地流程，以及将服务组合和负载均衡结合集群概念，研究服务组合的QOS。这些将成为新的挑战，文中通过PDG图进行等价分解，并结合QOS，通过实验测试引擎负载，提出将负载均衡融人服务组合QOS研究思想

Abstract:: Web service composition consists of orchestrated Web services. Web service composition can be divided into two classes, narndy centralized architecture and decentralized architecture, by the location of the Web services composition engine. Decentralized Web services composition can solve the problem of scalability,message exchange efficiency, autonomy and load. But it＇s big challenge to partition a cornposite Web service written as a single BPEL program into an equivalent set of decentralized processes, to study the composite Web service QOS by the host set conception,Web services composition method and load balance of Web services engine
