Timetabling and energy
A bi-level model coordinates departures, section running times and passenger demand while accounting for propulsion and levitation energy.
Transportation Research Part E, 141: 102007
Qingying Lai, Jun Liu, Ali Haghani, Lingyun Meng, Yihui Wang
Speed-profile optimization
Dynamic programming and mixed-integer linear programming are used to optimize energy-efficient speed profiles with auxiliary stopping areas, nonlinear resistance and levitation energy.
Journal of Central South University (Science and Technology), 50(6): 1499–1506
