铁路客运站到发线运用优化研究

Optimization Research for Utilization of Arrival and Departure Tracks in Railroad Passenger Station

详细分析客运站旅客列车到、发技术作业。把客运站到发线运用优化目标分解为方便旅客旅行、有利于保证行车作业安全与行车技术作业和有效地使用车站各种既有行车技术设备等三个子目标,并分别建立其优化模型。运用多目标规划理论与分枝定界法对模型进行求解。依据某大型双线通过式客运站的实际数据,应用优化模型进行到发线运用实例分析计算,计算所得方案的优化效果明显。

The technical operation for passenger train arrival and departure at passenger station is analyzed in detail. The target of utilization of arrival and departure tracks at passenger station is divided into three sub-targets and optimization model for each sub-target is established respectively, namely convenient ride for passengers, safety assurance for both train operation and technical operation, and effective utilization of the existed technical equipment for train operation at station. The model is calculated by applying multi-target programming theory as well as branch and bound method. Based on the actual data of a certain large double line through-type passenger station, the optimization model was used to calculate the utilization of arrival and departure tracks. The optimization effect from the calculated solution is evident.
