大型铁路客运站列车进路优化模型与算法研究

以提高车站行车技术作业效率,保证车站行车作业安全,尽可能减少旅客站内走行距离和时间,保证发车时间相近的两列始发或通过列车尽量不停靠同一站台,提高车站既有行车设备利用率为优化目标,建立大型铁路客运站进路优化的多目标规划模型.运用层次分析法求出各子目标的权重,并构建启发式算法进行模型求解.通过对算法进行实例验证,得到了较优的列车进路安排方案.

Research on optimizing model and algorithm of train route for large-scale railway passenger station

The paper built the multi-goal programming model of utilization of arrival and departure track at the large-sized railway passenger station by taking utilization of arrival and departure track and safety assurance for both train operation and technical operation as the target which included reducing the running distance and time for passengers to go into the station or get out of the station,any two departure or nonstop trains whose departure times were close won＇t stay in the same platform as possible as they could,and effective utilization of the existed technical equipment for train operation at station such as balance the occupied and free time of every track.It was obtained each weight by ahp to optimization objective of model.The Heuristic Algorithm was selected to solve the model in this paper.The better application scheme of arriving-departure tracks was obtained under the real-life case of a large-sized railway passenger station.
