| 摘要: |
| 针对现有服务聚合流程建模方法的不足，基于扩展Petri网提出了一种新的服务聚合流程/资源描述模型WSCP/R-net，有效解决了动态服务聚合流程模型中不确定路径选择和服务的动态变化性问题。给出了WSCP/R-net模型向BPEL4WS的转换算法，并以城市应急处理为例说明了转换算法的有效性。 |

| Abstract: |
| To overcome the shortcoming of current web service composition modeling methods, a new web services composition process/resource model(WSCP/R-net) was proposed on the basis of the extended petri-net. WSCP/R-net resolves the problems on uncertain activity option and dynamic variation of service in process modeling effectively. Furthermore, a description of the methods to translate WSCP/R-net into BPEL4WS was made. Finally, its application was illustrated in city emergency disposal. |
