城际铁路旅客列车开行方案优化研究

Study on Optimization of Passenger Train Operation Diagram for Inter-city Railways

根据影响列车开行方案的列车交路、列车种类、列车停站方式相互影响、相互制约的特点,以满足客流量为基础,以减少动车组使用数量为优化目标,构建城际铁路列车开行方案的优化模型。该方法根据客流情况具体分析,选定列车编组方案,初步确定列车交路、列车种类和不同种类列车的停站方式,然后对相关方案的动车组使用数量进行计算,得出动车组数量最小的方案,进而最终确定列车开行方案。

According to the characteristics of inter-influence and inter-restriction influencing the train routing, train types and train stopping mode in station of train operation diagram, the train operation diagram of inter-city railway is established based on satisfying the passenger flow volume and taking the optimization target of reducing EMU use number. The method according to the detailed analysis on passenger flow status, selects train formation diagram, and primarily confirms the train routing, train types and stopping mode in station of different type trains, then calculates the EMU use number of relative diagram as to achieve the diagram of EMU use number minimized and finally confirm train operation diagram.
