Integration Optimization of Timetable and EMU Schedule for High Speed Railway

Abstract

Based on the analysis of the existing optimization model of train diagram and EMU schedule, combined with the theory and method of integration optimization, the integrated optimization model of high-speed train diagram and EMU schedule was constructed in this thesis, of which the objective function is to build the largest number of running lines between its zones. An EMU schedule plan which better satisfied the given traction plan was obtained in this thesis, using GAMS to solve the model. To test the effectiveness of the model as well as the method, the train diagram and EMU schedule scheme of Beijing-Tianjin Intercity Train was optimized and solved. The optimization results showed that for the EMU schedule of the Beijing-Tianjin line, the number of EMU trains could satisfy the actual operation of high-speed railways, while 6 more trains could be operated at the same time. This solution could provide support of high-speed railway train diagram and EMU schedule scheme for the Beijing-Tianjin line.
