多模式交通条件下合理制定旅客票价的优化模型及算法

Optimal Model and Solution Algorithm for Passenger-Ticket Pricing under the Condition of Multimodal Transportation

在本文中 ,充分考虑了旅客和交通管理部门两方面的利益 ,提出了一个双层规划模型来描述城市间多种交通方式竞争条件下合理制定旅客票价问题。在此模型中 ,既保障了旅客使自己的广义出行费用最小 ,又使得交通管理部门在客运市场的竞争中取得最大的经济效益。然后给出了求解该模型的基于灵敏度分析的启发式算法 (SAB)。

In this paper, the benefits of passengers and transportation management departments are both considered and a bi-level programming model is presented in order to seek the optimal passenger-ticket price under the competition between different inter-city traffic modes. The lower-level problem represents an equilibrium model that describes passengers' mode-choice behavior under the condition of multimodal transportation. The upper-level problem is to determine passenger-ticket price to maximize the revenue of transportation management departments while considering passengers' mode-choice behavior. A heuristic algorithm for the bi-level problem is also proposed. Finally the applications of the model and its algorithm are illustrated with a practical example.
