Abstract:Train scheduling plays a key role in the punctuality and reliability of the railway industry. When the train runs away from the plan, the dispatching department formulates the transportation adjustment plan and implements it to restore the train operation to the original plan as much as possible, reducing the impact on passengers and operational order. The problem of real-time adjustment of train operation under disturbance conditions is an important task of dispatching work under abnormal conditions of high-speed railways, and is an important part of transportation organization adjustment and optimization. This paper focuses on the problem of train rescheduling in the scenario of disruption in the high-speed railway segment, abstractes the operation of trains on the rail network into the occupation of discrete driving resources on the micro level, and establishes a mixed integer programming model under the certain failure duration with the goal of minimize the total delay time of all trains. The goal of the transportation adjustment is achieved by changing the train arrival time, running route, sequence, etc. We then solve the model by a linear programming commercial software called CPLEX. The paper takes the Beijing—Dezhou section of Beijing-Shanghai high-speed railway for example, verifying the effectiveness of the model of certain failure duration. The results show that the solution results and solution time increase with the increase of fault duration time. The proposed model can assist dispatchers to get the optimal scheduling solution in a short time after the failure occurs and improve the emergency handling ability of dispatching departments.
