With the speed increase of the railway and the construction of the passenger dedicated line, the application efficiency and maintenance quality of the EMU, as the main means of transport of the passenger dedicated line, are directly related to the safe operation of the passenger dedicated line. Therefore, it is very necessary to carry out high-efficiency and high-quality maintenance work for EMU. In this paper, the maintenance problem of EMU is studied. According to the different maintenance process of EMU under different conditions, a mixed nonlinear programming model is established, and the software is used to solve the shortest total time of maintenance of all EMU is 541 min. The model provides a reference for the optimization of maintenance of EMU in actual production and life, and is helpful to improve the maintenance efficiency of EMU.
