| 摘 要： | 为制定客运专线的最优运价,按费用敏感程度将旅客分为3类,用随机用户平衡理论建立了不同运输方式弹性需求的中间层模型和不同铁路运输产品的下层模型.在此基础上,建立了以铁路企业收益最大化为目标的上层模型.用相继平均法求解中间层和下层模型,用粒子群算法求解整个三层规划模型.算例结果表明:取客运专线最优运价时,在运输方式铁路、公路和航空,以及铁路内部产品客运专线与既有线之间,客运专线承担了较大的客运量.

| Abstract: | To optimize the fare of a high speed passenger railway line,passengers were divided into three groups according to their price sensitivities.The stochastic user equilibrium method was used to formulate an intermediate layer model for elastic demands to different types of transportation and a lower layer one for different transportation products within the railway,and a top layer model with the objective being to maximize railway income was built based on the intermediate and lower layer models.The intermedi... |
