摘　　要：城市间的多种运输方式存在着竞争关系,在给定需求下票价价格是各种运输方式的调节杠杆。本文提出了一个铁路旅客票价制定的双层规划模型。首先建立了一个描述用户多等级、路径多阻抗、多标准情况的变分不等式模型,并将其作为双层规划模型的下层模型,然后以铁路运营总收益为上层目标,建立了相应的双层规划模型,同时设计了求解此模型的基于混沌-修正投影算法的启发式求解算法。结果表明,本文提出的票价价格制定机制是合理的,有望为有关部门的定价机制提供理论依据。Competition exists in multiple intercity transportation means.Ticket price is the adjustment lever for the given requirements.This paper presents a bi-level programming model for railway passenger ticket pricing.We initially construct a variational inequality model that can represent multi-class,multi-path cost and multi-criteria.It serves as the down-level model of the bi-level programming model.We then establish the up-level model of the bi-level programming model with total railway income as an object.We also design a chaos-modified projection algorithm based heuristic algorithm to solve a bi-level programming model.Results show that the proposed ticket pricing mechanism is reasonable.It will provide a better theoretical basis for government railway ticket pricing mechanism.
