基于DAML-S和扩展Petri网的Web业务流程建模方法

An Approach for Modeling Web Business Process Based on DAML-S and Extended Petri Net

为实现Web上业务流程动态装载和调用以及跨企业业务流程的动态集成目标,提出了一种Web上的业务流程建模方法.该方法扩展了具有良好过程建模性能的Petri网,并将其与Web服务描述的本体语言DAML-S相结合.首先将Petri网扩展为业务流程建模,用DAML-S来描述流程模型,然后利用结合了DAML-S的UDDI注册中心来查找最佳服务,并在执行阶段动态调用合作伙伴提供的Web服务,从而实现了在企业间相对通用的一些业务流程的动态集成.通过一个实例对整个过程进行了验证讨论.

In order to realize the need of dynamically loading and calling Web services on Web to adapt to rapid changing business environment, a business process modeling based on the combination of DAML-S and extended Petri net method was proposed. It includes using extended Petri net to model business process, and using DAML-S to describe the model and utilizing UDDI imported with DAML-S to search proper services. Then based on these business process models, related web services could be provided to partners during the execution. Lastly, an example was provided to verify the whole process of business process modeling and service calling
