拟阵约束下TU模糊合作博弈的Banzhaf-Coleman值

本文利用公理化的方法对TU模糊合作博弈的Banzhaf-Coleman值进行了研究,引入拟阵约束分析了其有效性、可加性、单调性、非实质性、公平性和中立性,并论证了拟阵约束下Banzhaf-Coleman值的唯一性。该方法可用于联盟成员的势力大小的衡量,特别是对房地产开发商Cartel联盟的合作势力大小的评估,也可实现有效的收益分配方案。最后利用实例对该方法的有效性和可行性进行了说明。     

A new coupled-map car-following model based on a transportation supernetwork framework

A new car-following model is proposed by considering information from a number of preceding vehicles with intervehicle communication. A supernetwork architecture is first described, which has two layers： a traffic network and a communication network. The two networks interact with and depend on each other. The error dynamic system around the steady state of the model is theoretically analyzed and some nonjam criteria are derived. A simple control signal is added to the model to analyze the criteria of suppressing traffic jams. The corresponding numerical simulations confirm the correctness of the theoretical analysis. Compared with previous studies concerning coupled map models, the controlled model proposed in this paper is more reasonable and also more effective in the sense that it takes into account the formation of traffic congestion.
