THE MODELING METHOD AND REALIZATION OF THE POWER SYSTEM OVERHAUL AND REPAIR MANAGEMENT BASED ON WORKFLOW TECHNIQUE

Based on workflow technique, a new modeling method and algorithm for power system overhaul and repair management process are presented. Using the process-oriented technique, the overhaul and repair management information can be processed in computer network automatically. A task-based modeling idea is advanced, which takes the expanded P/T_system based on PetriNet as a workflow model. With the introduction of the workflow's definition, this paper explains the modeling principle and the approach of the overhaul and repair management process. The substrate support of the system is founded on the shareware document database and mails transfer technique, so the system has a interoperate ability to the distributed heterostructure environment. The system has been successfully applied to the overhaul and repair management information system (MIS) project of a electric power supply company and is proved to be feasible and effective.
