摘　　要：在既有铁路货物列车运行线选择优化研究的基础上,分析列车运行线选择与机车周转之间的相互影响关系,综合考虑市场满意度和铁路运输成本,以货物运输时间最小和铁路资源运输成本最小为目标,对列车运行线选择和机车周转进行协同优化。本文以机车在折返站的接续周转时间最短为下层规划,以运行线在技术站无调中转作业时间和机车在折返站的折返作业时间等为约束条件,建立了直通货物列车运行线选择优化的二层规划模型,并设计了以粒子群算法为主体的优化求解算法。案例结果显示,模型和算法的有效性得到了验证。Based on current research of the optimization of the path selection of railway freight trains,the interaction between the selection of train paths lines and locomotives turnaround were analyzed,and market satisfaction and railway transportation costs were comprehensively considered.With the goal of minimum freight transportation time and the minimum transportation cost of railway resources,the train paths selection and the locomotives turnaround were collaboratively optimized.Taking the shortest locomotive turnaround time at the turnaround station as the lower-level programming,and taking the detention time of the train paths without resorting at the technical station and the locomotive turnaround time at the turnaround station as the constraints,a bilevel optimization model for the optimization of the train paths selection of the through freight train was established.And the optimization algorithm based on particle swarm optimization was designed.Finally,a case was given to indicate that the validity of the model and algorithm was verified.
