基于合作性投资和价格策略的多式联运企业协作行为博弈分析

本文对联合运输中不同运输企业间的协作行为进行了研究。考虑了两家提供互补运输服务的寡头运输企业之间的合作和竞争的博弈决策问题,通过定义合作强度参数,并将其引入收益函数,构造了合作性投资和价格策略的两阶段动态博弈模型,讨论了该博弈子博弈完美Nash均衡解的存在条件,推出了一些重要的结论。研究发现:当双方投资效果系数组合在(0,1)区间时,随着市场潜量的增加,投资增长;随着价格弹性的增加,投资下降。而当双方投资效果系数组合在(1,2)区间时结论相反。最后通过算例和所设计的免疫遗传算法进行了不同参数环境下的数值模拟,验证了结论的正确性。

Cooperation Investment-Price Game Theoretic Model in the Intermodal Freight Transport

This study focuses on the collaborative behavior analysis of the different carriers in the intermodal freight transport,a making-decision problem on Cooperation and competition between the two oligopoly transportation firms which provide complementary transport service is considered.Based on the game theory,a two stage dynamic game model with complete information on cooperation investment and price strategies is formulated.We discuss the existence of unique subgame perfect Nash equilibrium of the game.Using...
