This paper introduces the game theory and sets up, based on it, the choice model for the public transportation priority by identifying the function of the payoff and the muster of attendee and stratagem. In addition, it analyses the existence of NASH equilibrium, and puts forward the arithmetic of Iterated Elimination of Strictly Dominated Strategies in the general condition, the Integrated Strategies in the special condition and the flow chart of the model. At last, it verifies the feasibility of the model with the given example.

本文采用了博弈论的理论，通过对公交优先系统中参与者集合N、战略集合S和收益函数u的确定，建立了一种基于博弈论的公交优先技术方案选择博弈模型来量化方案选择问题；在此基础上分析了NASH均衡的存在性，并且给出了一般情况下的重复剔除劣战略和特殊情况下的混合策略两种模型求解方法以及公交优先技术方案选择博弈模型的流程图；最后通过算例分析，验证了博弈模型应用于公交优先技术方案选择的可行性。

Network service states were regarded as basic situational elements, network offense and defense behaviors were both taken into account, gambling model for network security situation was constructed, in which the model parameters such as state space, strategy set and payoff function were definitely formulated. By simulation experiment, the Nash equilibriums was computed when attackers and defenders got a balance between payoffs, then quantitative depict of network security situation was accomplished.

该方法将网络服务状态作为基本态势要素，综合考虑网络系统中存在的攻防行为，建立了网络安全态势博弈模型，并对状态空间、策略集和效用函数等模型参数给出了明确定义，经仿真实验找到该模型的Nash均衡解，在均衡局势下攻防双方达到收益平衡，完成了对网络安全态势的定量刻画。

The payoff function v thus defined is proved to have supperadditivity,and the Shapley value so defined proved to satisfy axioms such as efficiency,symmetry,dummy and additivity.The fuzzy Shapley value method for profit allocation in enterprise coalitions was thus given by examples.

并证明了支付函数v具有超可加性，以及Shapley值满足有效性、对称性、哑元性与可加性的公理体系，实例证明了企业联盟收益分配的模糊Shapley值方法。

The experiment of privates providing public goods includes subjects, initial endows, providing mechanism and payoff function, the reason that the practical voluntary contribution excels the dominant equilibrium is human behavior with homo-economics, including pure altruism, warm-glow effects. reciprocal, conformity effect and noise; Reducing the contribution cost may improve the level of voluntary contribution, incentive mechanisms include dynamic game, stake distribution, encouragement and punishment, symmetrical information, communicating each other and re-grouping.

公共产品私人提供实验一般包括实验受体、初始禀赋、供给机制和支付函数等，公共产品私人提供偏离占优策略均衡主要是因为人的行为对利己、理性的背离，包括利他主义、光热效应、互惠行为、遵奉效应以及噪音或决策失误等；而通过降低公共产品的私人贡献成本可以提高公共产品私人贡献水平，这种激励机制主要包括博弈动态化、合理分配赌注、建立奖惩机制、公开贡献信息、受体相互交流以及受体重新分组等。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
