摘　　要：通过Web服务构建复杂应用存在的问题是:Web服务是无状态操作,所以只能提供相对较小的原子应用。但Web服务是可以集成的,这是它的一个重要特征。因此,可以通过原有Web服务的组合构成新的更复杂、功能更强大的Web服务。Petri网理论作为组合Web服务的一个主要机制,可以用来快速创建功能更强大的Web服务。该文围绕Petri网理论在Web服务组合中的应用,研究如何基于Petri网构建Web服务动态组合的模型,从而实现Web服务的集成。The adoption of Web services to build complex applications will be：Web services are stateless operations, thus only providing for small,atomic applications. But Web services are composable, which is an important characteristic of Web services. Therefore, we can through a combination of the original Web services constitute a new and more complex, more powerful Web services. Petri net theory as an important primary mechanism of Web services composition for the rapid creation of new and more powerful Web services is critical. In this thesis,focus on the implementation of Petri net theory in Web services composition,describing how to achieve the integrated Web services based on Petri net modeling dynamic composition of Web services.
