A risk appraisal system regarding the implementation of maritime regulations by a ship operator

The shipping industry operates in a regulatory framework, where the International Maritime Organization (IMO) is the leading regulatory body. The role of the IMO is to propose maritime regulations to its member states. The successful worldwide implementation of a maritime regulation depends on how many member states adopt it. However, many maritime regulations are not adequately implemented worldwide. As a result, ship operators have found themselves in an uncomfortable position in developing their business in an unstable regulatory regime. This paper proposes an extendable and applicable methodology involving a System of Hierarchical Scorecards (SHS) to measure the implementation costs and benefits of a newly introduced or existing maritime regulation by ship operators. The regulators may use the results in evaluating newly introduced and/or existing regulations through taking into account the economic burden that will be generated to ship operators. In this paper, SHS is extended to demonstrate its applicability on evaluating a ship operator’s organization with regard to his regulatory implementation performance by the means of a case study.     

Game theory analysis of quality control in two-echelon supply chain

Game theories were used to study the problem of quality control in the two-echelon supply chain which has one manufacturer and one supplier in this paper. Firstly, a stackelberg game was introduced into the quality control of a two-echelon supply chain. In this general non-cooperative quality control game situation, the manufacturer acts as the leader, the optimal action policies were obtained for the manufacturer and the supplier. Then, a Nash bargaining model was used to analyze optimal action selection in the cooperative quality control game situation and to determine the profit segment between two supply chain members after collaboration. By comparison of two game equilibrium results above, it was found that the cooperative quality control game structure is superior to the general non-cooperative quality control game structure during the process of quality management in the two-echelon supply chain. Finally, a numerical example is given to illustrate the conclusion of this paper.

通过对出租车市场中出租车司机、黑出租车、消费者、政府几者的主体利益分析,运用博弈论的方法分析出租车市场上出租车公司与出租车司机,出租车司机与乘客,出租车公司与政府,黑出租车与政府这些利益主体几者的博弈关系,说明出租车规制对各方利益博弈均衡的影响。通过对政府管制下出租车行业的利益主体的博弈分析,说明出租车行业管制对行业利益分配的影响,为出租车行业管制的发展和改革提供理论依据。     

基于博弈论的多利益主体绿色供应链两阶段博弈分析

本文主要研究绿色供应链多利益主体的博弈行为和决策选择问题。首先提出了包含制造企业、政府、分销商与消费者的绿色供应链多方博弈分析框架。其次,通过博弈理论合理构建了两阶段博弈,第一阶段针对制造企业、政府、消费者三者进行博弈分析,第二阶段基于委托代理机制针对制造企业与分销商进行博弈分析。最后从理论上分析绿色供应链中各方优化协调的效率,重点分析在政府参与下,不同博弈策略对绿色供应链管理的影响。

基于利益渴望原则的航空网络争当操纵者四方博弈模型

航空网络的演化过程是基于航空网络参与者的利益渴望而形成的一个利益均衡的过程.航空网络的参与者包括航空公司、乘客、航空交通管理部门,及以机场为代表的地方政府.为了分析航空网络在四方参与者利益渴求基础上的演化模式,设计航空网络以四方利益得失为衡量依据的动力学演化过程,判断四方参与者的利益变化.模型显示随着航空网络演化次数的增加,航空网络的节点的度的均值呈现典型的线性下降趋势,并随着演化的逐步推进,最终实现航空网络的四方利益均衡.     

不同回收价格的闭环供应链收益分配问题研究

在构建的包含一个制造商和两个零售商的闭环供应链中,对两个零售商的回收价格加以区分,采用博弈论方法,分别基于零售商分散决策和集中决策的情境,分析供应链整体与节点企业的最优收益分配,并通过算例验证了研究结果.研究表明：两个零售商回收价格不同时,制造商的收益在零售商分散决策时优于零售商集中决策时,零售商的收益则受益于零售商的合作,并且闭环供应链的整体收益在市场容量较大时选择零售商分散决策较优,而在市场容量较小时选择零售商集中决策较优.     

博弈论视角下的交通分配系统最优与用户均衡的探讨

为了更好地解释系统最优与用户均衡两种交通分配方法间的定量关系,透过博弈论的视角,通过对算例的非合作博弈分析,从无限策略集下纯策略Nash均衡的角度指出了系统最优与用户均衡的统一性,二者作为Nash均衡的两种特殊状态,可以随博弈局中人数的变化而相互转化.同时,还对系统最优与用户均衡的转化过程进行分析,阐述其两阶段特征及对实际分配状态的影响,并通过在多场景中调整路阻函数的各项参数,指出路径的自由流走行时间作为＂初期优势＂,对转化速度和方向具有关键性影响.     

建筑节能激励政策的演化博弈分析

为有效实施建筑节能激励政策,运用演化博弈论的方法,对政府和房地产商群体之间相互作用时的策略选择行为进行分析,给出双方最优策略建议.考虑到博弈双方有限理性不均等及房地产商个体间理性不均等的事实,进一步对政府策略提出修正,并构建房地产商二次演化博弈模型.根据演化博弈分析的结果,认为:政府坚持建筑节能的高理性信念,运用激励政策在房地产商群体内形成二次博弈,淘汰"短视"者,培养"有远见"者,最终政府与房地产商群体达到双赢.
