In the subway metro, the failure of the power supply system affects normal operation and brings many inconveniences to passengers. This paper proposes a train timetable rescheduling (TTR) model under power supply system failures. First of all, an optimization model that takes the deviation of rescheduled timetable and the cancellations of train services as the objectives is developed. In addition, train detention strategy and the strategy of dropping off trains in the storage line, as well as the constraint of increased headway in power supply failure area are considered in the model. Secondly, for the ILP problem can be solved by the existing solver (such as Cplex), the model is transformed into an integer programming model through linearization. Finally, some case studies are conducted based on the actual data of Beijing Fangshan Metro Line to demonstrate the effectiveness of the proposed approach. The results show that the rescheduling model in this paper is feasible in actual metro lines.
