摘要
针对Petri网在服务组合中的具体应用问题,尤其是如何构建基于Petri网的服务组合软件平台,在服务组合的Petri网模型的基础上,首先建立了具体领域中服务的语义功能体系;然后进行原子服务的注册及发布,将各具体服务绑定到语义功能体系中的某一功能;其次实现了基于视图的服务组合构建,用户可在相应视图中通过选择相应的功能进行方便的服务组合构建,并得到相应的服务组合功能流程;最后进一步将相关功能转换为绑定具体服务实例的Petri网模型,并交由相应的基于Petri网的服务组合执行引擎实现执行。实现了从服务组合构建到执行实现的完整功能流程,为基于Petri网的服务组合动态执行相关问题的分析提供了软件平台支撑。
According to the specific application of Petri net in service composition,Petri net based the service composition software platform was constructed in this paper.Firstly,semantic based service function system is established for domain services.And then,atomic service is registered and published,and it is tied to a concrete function in the semantic function system.Secondly,view based service composition construction is realized,and users can select services,construct service composition through related view and get service composition function process.Furtherly,Petri net of service composition can be get and submitted to execution engine,completing the execution of service composition.The work of this paper realized the process from construction to execution for service composition and will provide software support for the use of Petri net within dynamic execution of services composition.
