Abstract:
To reduce the operation cost and then improve the operational efficiency, people are paying more and more attention to the energy-efficient operation of subway systems. In this paper, we present and compare to two algorithms to optimize the energy-efficient speed profile for trains of subway systems, which can reduce the energy consumption of train operations. Firstly, we formulate a mixed integer linear programming (MILP) model to get the optimal trajectory for trains. Secondly, we present an integrated algorithm for optimizing the timetable for the entire route together with the speed profiles between successive stations, which is called as integrated timetable. Finally, we give some numerical examples to illustrate the validity of the algorithms based on the data from the Beijing YiZhuang subway line in China.
