Abstract: An optimization approach for the circulation problem of EMUs in high-speed railway was proposed. It optimizes the circulation plan of EMUs to minimize the number of EMUs under the constraints of EMUs maintenance,empty return, and reconnection. Firstly, the basic 24-hour railway timetable of China was augmented by seamlessly splicing two single-day railway timetable so as to form an augmented railway timetable that runs on a 48-hour cycle. Then based on the augmented timetable, the EMU connection network was constructed and a linear integer programming model was put forward as the EMU train flow model. Lastly, a model was built through OPL language and the railway timetable data was entered into it, calling CPLEX solver found a solution to it. The results show that the optimization method proposed in this paper can solve the problem of EMU circulation successfully.
