摘要
以枢纽小运转列车运营成本和货运站装卸费用最小为目标,考虑载重量、列车数和运行时间约束,建立了枢纽小运转列车路径优化模型.并以某铁路枢纽地区为例,运用ILOG CPLEX优化软件仿真求解,得出枢纽小运转列车的最优路径方案.实例证明模型是有效可行的,与实际运行比较,优化后的费用降低近5%,运输距离缩短近8.31%.
A routing optimization model of local trains is proposed considering capacity, train number and run- ning time, and the optimization objectives of the model were to minimize the operation cost of local trains and artificial cost of freight stations. One railway terminal is treated as an example that was optimized by ILOG CPLEX. The result proves that the routing optimization model is effective and feasible. Compared with actual situation, the cost is reduced by nearly 5 % , and running distance is also reduced by nearly 8.31%.
