Abstract: The rational and scientific nature of metro vehicle maintenance plan is one of the important factors for ensuring the healthy state of vehicle. Based on the metro vehicle repair business requirements analysis,and conflict detection of three constraints of track, vehicle, operational plan, vehicle maintenance daily plan formulation method is optimized and vehicle base intelligent integrated management and control system architecture is established. The vehicle maintenance daily plan formulated on the basis of intelligent integrated management and control system allows to seek the optimal vehicle maintenance and repair daily plan,to promote the maintenance scheduling management refinement,informatization and intellectualization,and to enhance the transportation resource utilization,to decrease the cost of operation and maintenance,to reduce the hidden safety danger caused by excessive or lack of maintenance of some vehicle equipment at the same time.
