拥塞服务网络上的寡头竞争

摘要

研究拥塞服务网络中寡头快递服务商关于价格竞争的均衡问题.描述了拥塞服务网络并构建了寡头服务商竞争的二层均衡EPEC模型.证明了寡头服务商竞争的Nash均衡的性质以及存在性.给出简单算例.研究结果对服务网络环境下的寡头服务商竞争有借鉴意义.%The price equilibrium between oligopoly service providers in service networks with congestions was studied. The bi-level MPEC model of service competition in service networks was described. The lower level is Wardrop equilibrium between customers, while the upper level is the Nash equilibrium between service providers. The existence of the price oligopoly equilibrium was proved and its properties were analysed. The practice in the express service industry in China was discussed. A numerical example was given to show that service providers should take the customer preference into consideration when making decisions.
