摘　　要：Web服务为软件构件和构架技术的研究也为 Web服务的应用奠定了一定的应用基础.在构件组装中,如何支持适应用户需求的 Web服务的组装是当前研究的热点之一.该文提出了一种基于优化算法的、支持领域特性的Web服务组装方法,该方法的核心是面向 Web服务应用,按照用户确定的功能和QoS需求,基于现有领域模型和Web服务QoS属性,将特定领域的优化组装转化为数学优化问题加以解决.这一方法可以较好地适应用户需求的更改并可以辅助用户选择服务.该文最后给出了支持该方法的原型工具的实验结果,用以说明该方法的可行性与有效性.The development of Web Services provides an industrial basis for the research of software component. The research of software component and architecture provide the basis for the application of Web Services. On the basis of component composition, how to deal with the composition of Web Services that comply with requirements of customer has become the hotspot research. This paper puts forward a method of Web Services composition that based on the optimization algorithm to support the specific domain feature. According to the customer’s specific requirements of function and QoS, the core of the method is to transform the specific domain Web Services composition problem to the optimization problem based on domain model and Web Services QoS. The preliminary experimental results show that above method can help user select proper services and is quite feasible for solving problems with real world sizes.
