摘　　要：在铁路货运市场化改革背景下,提出了综合优化货运定价与车流径路问题的必要性。在需求价格反应函数和车流弧-路模型的基础上,以铁路公司收益最大为目标函数,建立了铁路集装箱运输定价与车流径路综合优化模型,并设计了改进的遗传算法求解。最后以广州铁路(集团)公司的6个集装箱运输站为案例,验证了模型和算法的可行性和优越性。Against the background of the reform of the railway freight transportation market,this paper points out the necessity of the comprehensive optimization of freight transportation pricing and the routing of the car flow.On the basis of the demand price response function and the traffic flow arc-road model,it establishes a comprehensive optimization model of the railway container transportation pricing and car flow routing with the maximum profit of the railway companies as the objective function,and designs an improved genetic algorithm to solve the model.At the end,through a case study on six container stations of Guangzhou Railway(Group)Company,it verifies the feasibility and superiority of the model and algorithm.
