Research on Situation Deduction and Optimization Adjustment of Train Delay

With the gradual market-oriented of railway freight transport organization reform and the development of logistics mode, the requirements of freight transport for timeliness have become more accurate. This paper established the train delay deduction and adjustment model. Taking the train delay as the starting point, the influence of delay propagation and the line situation are analyzed. By optimizing the adjustment scheme, the train delay time is shortened and the delay effect is reduced. At the same time, considering the cost waste caused by train overtaking adjustment, the weight coefficients were used to optimize the delay loss and overtaking cost. Taking the Jinshan line data as an example, a designed case of delay verifies the effectiveness of the model. The results showed that the research can accurately calculate the delay propagation and provide corresponding adjustment schemes, provide scientific support for railway freight transportation decision-making, and enhance market competitiveness.
