中文摘要：
Web Services正逐渐成为主流的平台独立的软件构件，并广泛地存在于INTERNET分布式环境中，通过组装Web Services生成系统的开发方法正在逐步引起人们的关注并受到重视，但目前还没有提出一套相对成熟的、系统化的组装方案用于指导Web Services组装系统的整个开发过程．将特征模型作为贯穿整个Web Services组装过程的模型工具，利用它驱动Web Services组装系统的需求分析、流程建模、组装、部署和执行，提出了“特征模型驱动的Web Services组装”解决方案，并结合一个具体的实例对FWSC（feature model driven Web Services composition）案的基本思想、原理以及关键步骤进行了介绍．该工作可以有效地提高Web Services组装系统的建模、开发速度和质量，并增强Web Services组装系统在需求发生变化时的动态调整和演化能力．
英文摘要：
Web Services are gradually becoming main platform-independent software components and will widely exist in the distributed environment, INTERNET. This kind of software developing method that the creation of new software systems will mainly depend on Web Services composition is attracting more and more researchers＇ attention. There is still not a systematic and mature approach for Web Services composition which can be used to instruct the whole composition process. This paper provides a ＂feature model driven Web Service composition＂ approach, which makes Feature Model as the modeling tool to cross through the whole Web Services composition process and can be used to drive and direct all the phases in this process, including requirement analysis, business flow modeling, services composition, business flow deployment and execution. Then, combining with a concrete example, the basic idea, rationale and key steps of FWSC （feature model driven Web Services composition） solution are introduced. The work presented in this paper enhances the speed of modeling, development and quality of Web Services composition, and increases the abilities which can make the system dynamically adjust and quickly evolve when requirement changes.
