A Sparse Optimization Approach for Energy‐Efficient Timetabling in Metro Railway Systems

Journal of Advanced Transportation, Volume 2018, Issue 1, 2018., 2018
In this paper, we propose a sparse optimization approach to maximize the utilization of regenerative energy produced by braking trains for energy‐efficient timetabling in metro railway systems. By introducing the cardinality function and the square of the Euclidean norm function as the objective function, the resulting sparse optimization model can ...
