公交系统随机平衡网络设计模型及求解算法

A Stochastic Equilibrium Network Design Model and Its Solution Algorithm for Transit System

本文根据公交网络的具体特点，对公交网络进行了系统的描述，提出 一个双层规划模型来描述随机平衡公交网络设计问题。在双层规划模型中，上层 模型为一个标准的公交网络设计模型，下层模型是一个公交网络随机平衡配流 模型。针对所提出的模型，设计了基于灵敏度分析的求解算法。最后，给出一 个简单算例加以证明。

According to transit network characteristics, transit network is systematically described in this paper. A bilevel programming model for transit network design problem is presented, in which the upper model is a normal transit network design mode l, and the lower model is a transit stochastic equilibrium assignment model. A heuristic solution algorithm based on sensitivity analysis is designed for the model proposed. Finally, a simple example is given to illustrate the application of the model and algorithm suggested.
