摘要
对公交网络系统的经营博弈问题进行了研究分析 .以公交车车费作为经营者的决策变量 ,建立了经营者之间广义 Nash均衡博弈模型 ,并表示为一个拟变分不等式问题 .证明了所得到的效用函数是凹函数 ,从而保证了广义 Nash均衡解的存在性 .并将求解拟变分不等式问题 ,转化为求解一个等价的一般变分不等式问题 .最后 ,给出了详细的算例分析 .
This paper presents a network equilibrium model for a deregulated transit system that can be used to describe the competition between different transit operators. The transit competition is portrayed as a n player, non cooperative game by changing the fare structure between a set of transit lines so as to maximize the profit of each transit operator within the oligopolistic market. A logit type choice model is used to predict the passenger choices on arriving vehicles of various lines between any two consecutive transfer stations for their travel. A generalized Nash equilibrium will be achieved, which can be formulated as a quasi variational inequality problem. Finally, a heuristic solution algorithm is proposed. A numerical example is given to illustrate the competition mechanism on the transit network.
