Research on high-speed railway operation adjustment model based on priority

Purpose This paper aim at providing decision support for operational adjustment. In order to effectively reduce the external interference impact on train operation. Design/methodology/approach According to the reality that there are two kinds of high-speed trains running in China, considering the reality that there are two speed level train running in Chinese high-speed railway, this paper proposed the high-speed railway operation adjustment model based on priority, and the objective function is to minimize interference impact on train operation. Findings Adjustment strategy based on priority than based on sequence can effectively reduce the interference influence on train operation, which makes the train resume the planned operation back on schedule more quickly. Research limitations/implications The solution of large-scale cases is too slow, and the practical application is limited. Originality/value The model was verified by a case, and the case results proved that adjustment strategy based on priority than based on sequence can effectively reduce the interference influence on train operation, which makes the train resume the planned operation back on schedule more quickly.
