摘    要:为了将分布在Internet上异构的Web服务组装成新的服务提供给用户,提出一种面向用户的Web服务组装方法,将组装过程分为需求拆分、服务选择、执行服务组装和服务结果合并四个阶段,并提出了基于组装模式的用户需求输入及拆分方法、基于QoS的服务选择模型和基于中间模式的异构消息转换模型.最后通过物流领域服务组装平台的设计与实现,验证了上述方法的可行性与有效性.

关 键 词:Web服务组装  需求拆分  服务选择  异构消息转换  中间模式

Abstract:To compose heterogeneous Web services distributed on Internet to a new service provided to customer, a user-oriented Web service composition method was proposed, which divided composition process into four phases, as division of user's needs, selection of Web services, implementation of Web services composition and combination of the output of Web services composed. Also a composition schema-based method for user needs input and division, an effective QoS-based model for Web services selection, and a middle schema-based heterogeneous message transformation model were proposed. Finally, a Web service composition platform applied in logistic area was designed and implemented to show the feasibility and effectiveness of the methods above.
Keywords:Web service composition  needs division  service selection  heterogeneous message transform  middle schema
