Abstract: This paper proposes a combination scheduling method with deadheading strategy for an urban subway line which connects residential areas and workplaces during the morning rush hours. The deadheading strategy means to let parts of trains directly return to the departure terminal without stopping along the smaller demand direction, in order to dispatch more trains along the larger demand direction subjected to the given number of electronic multiple units (EMU). The problem is formulated as a nonlinear programming model. The genetic algorithm is therefore adopted to solve the constructed model. Finally, the proposed model and algorithm have been successfully tested with the help of a real case.
