| China’s high-speed railway developed rapidly in recent years. EMU Operation Maintenance was an important guarantee for the safety of high-speed railway security operations, whose quality and effectiveness were key factors relating to EMU security and rapid development.EMU Operation Maintenance required multi-sector professionals work together to complete, whose business process was complex and repair process was different between the various EMU models, and by introducing workflow technology, the problem of flexible configuration process was solved well. On the other hand, application of mobile network technology got rid of dependence on the time of the repair work and the region. The combination of mobile network technology and workflow technology made the EMU overhaul efficiency greatly improved, furthermore, promoted the development of refinement and standardization of maintenance operations.This thesis first introduced the background, significance of EMU Maintenance Operation Process Management System, and the current research and main research direction, then, studied on generic modeling methods and methods of analysis of the work flow, and by analysis of EMU maintenance processes, summarized the main related business processes, and the workflow process modeling and analysis was carried out by using Petri net technology. Considering the system requirements, main function modules and structure design and the key technologies adopted were presented, and finally data model design using mobile workflow and technical implementation were introduced in detail. |
