摘　　要：Web服务的发展将Web应用从信息交互领域扩展到了服务交互领域。Web服务诸多的特性使得它非常适合于商务应用集成,因此工业界和学术界都希望能够通过合成多个Web服务从而获得增值的新服务。在服务合成的过程中,不仅需要语义清晰的服务描述语言和直观的建模方法,并且应该能够动态地发现构件服务,顺利地执行复合服务以及对其进行事务处理。此外对Web服务合成的分析评估也将有助于理解复合服务中每一项活动的行为,从而促使不断改进服务合成技术。The development of Web Service has extended the role of Web applications from information interaction to service interaction. As we know, Web service technology is suitable for business applications integration. Therefore, researchers both from industry and academy try to compose individual Web services to obtain a new value-added service. In the process of service composition, we not only need semantically clear service description languages and intuitive modeling methods, but also want to have abilities of dynamic service discovery, service execution and transaction processing. Furthermore, performance analysis for Web services can help implementers understand the behavior of every activity in a composed process and improve the service composition technologies.
