摘要
针对带有分支和汇合结构的并发服务组合问题,提出了一种Web服务组(WSC)模型。WSC模型除了能够描述多个前驱服务或多个后继服务同时需要被组合的并发组合关系和顺序组合关系外,还能保证被组合服务的可执行性。在此基础上,扩展基于服务链组合方法,提出一种基于服务组链的服务组合方法。该方法能够采用统一的方式处理顺序服务组合问题和并发服务组合问题。最后通过实验和实例证明了本文方法的有效性。
A Web service community (WSC) model to deal with the simultaneously occurred service composition problem with branching and merging structures. The WSC model can not only describe the parallel and the sequential composition relations where the multiple forerun and follow-up services need to be combined but also guarantee the implementation of each combined service. Moreover, spreading the service community chain based composition approach, a Web service composition approach was proposed based on the service community chain. The approach can deal with the sequential and the parallel service composition problems in a unified way. The proposed approach was verified by experiments and case studies.
