基于扩展WF-Net对配电网故障诊断与抢修流程进行了建模与优化。首先将流程涉及的信息系统封装成具有松散耦合特性的 IT 服务；然后扩展了 WF-net 的时间集和颜色集，提出了基于 IT 服务的赋时有色工作流网(TCWFN-ITS)，以显式地表达业务流程与IT服务的调用关系。最后，针对某电力公司配电网故障诊断与抢修流程，采用TCWFN-ITS进行建模，使用Petri网建模工具CPN Tools进行仿真分析，通过并行执行任务、合并任务、优化服务占用端口数量等手段，实现了配电网故障诊断与抢修流程性能提升和 IT 服务的平衡配置，验证了所提方法的可行性和有效性。

The modeling and optimization of distribution network fault diagnosis and repair process has been researched, based on the extended WF-net. Firstly, information systems were encapsulated into the loosely-coupled IT services. Secondly, the time set and color set of WF-net were extended, then the Timed Colored WF-net with IT Services (TCWFN-ITS) was put forth to explicitly demonstrate the calling relationship between business processes and IT services. Finally, this paper illustrates with a power company’s distribution network fault diagnosis and repair process, employs TCWFN-ITS for modeling, and applies Petri net tool-CPN Tools for simulation analysis to enhance the performance of business processes and balance the calling of IT services, and verify the feasibility and effectiveness of the proposed approach.
