Abstract

The authors proposed a comprehensive mathematical formulation as a linear/nonlinear programme for considering energy-saving train scheduling. The formulation is to optimize running time for each section between stations with fixing total time between origin and destination of a train. The original fundamental manner of optimization named \“identical incremental energy consumption” was introduced. The model was extended and applied to a simple railway line model with six stations and five interstations. It could be solved with a general-purpose optimization library on a PC. The result showed that optimal condition and energy saving effect could be evaluated easily. Several percent of energy was saved by the optimization process. Keywords: saving energy, train scheduling, optimization.
