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.
