价格合同博弈的最优解探析

合同是企业间交易的表现形式,是维系供应链上下游企业之间最基本商务关系的纽带。一切合同中价格合同的形式最简单,合同订立是供求双方博弈的结果。文章利用报童模型,探讨合作博弈机制;然后采用两阶段规划方法讨论了价格合同下1M1R系统博弈的最优解。

虚拟股股东权益保护路径探析

对虚拟股进行定性分析确定,虚拟股股东保护存在入债模式合同路径保护和入股模式章程中心保护的二分选择,对两种路径进行比较分析发现,入股模式下虚拟股制度发展将会偏离其创设初衷,而入债能更好地实现双方利益最大化。但如若单纯依靠合同路径保护对缺乏博弈能力的普通雇员有失公允,所以以虚拟股合同路径保护为中心,引入声誉资本、诚实信用原则等机制对其进行碎片化修正十分必要。

Cooperative driving model for non-signalized intersections with cooperative games

Cooperative driving around intersections has aroused increasing interest in the last five years.Meanwhile,driving safety in non-signalized intersections has become an issue that has attracted attention globally.In view of the potential collision risk when more than three vehicles approach a non-signalized intersection from different directions,we propose a driving model using cooperative game theory.First,the characteristic functions of this model are primarily established on each vehicle’s profit function and include safety,rapidity and comfort indicators.Second,the Shapley theorem is adopted,and its group rationality,individual rationality,and uniqueness are proved to be suitable for the characteristic functions of the model.Following this,different drivers’characteristics are considered.In order to simplify the calculation process,a zero-mean normalization method is introduced.In addition,a genetic algorithm method is adopted to search an optimal strategy set in the constrained multi-objective optimization problem.Finally,the model is confirmed as valid after simulation with a series of initial conditions.

The Mechanism Research of Green Supply Chain Synergy Profit Distribution Based on the Shapley Value Method

Under green supply chain mode, how to Carry out the distribution of profits between subjects is an important problem. Through the comparison of the green supply chain benefit allocation of non-cooperative game and cooperative game the payoffmatrix, it is clearly that the necessity of interest distribution cooperative game. Put general manufacturing enterprises of green supply chain as the research object, using Shapley value method for theory analysis and example verification, vertifys that enterprise synergy gains more than their own separate management, and puts forward a feasible path of supply chain collaboration through the construction of the distribution of interests coordination model.

虚拟股的定性观察与规则探微——以虚拟股股东保护为中心

虚拟股的定性观察决定了虚拟股股东的保护机制的二分选择:是债的合同中心主义还是股的章程中心主义。然而一元保护机制在变动不居的市场背景下皆有不周延之处,存在盲区,尤其在公司主体发生重大变化如解散、收购时,虚拟股股东的失语处境使其无法得到应有的公允保护。为此,在后金融危机时代,针对虚拟股股东的保护路径也亟须从二分法则的单边主义向碎片化的多元主义做应时转化。

虚拟股的定性观察与规则探微——兼论虚拟股股东保护的碎片化修正

虚拟股的定性观察决定了虚拟股股东的保护机制的二分选择:是从债的合同中心主义还是从股的章程中心主义。然一元保护机制在变动不居的市场背景下皆有不周延之处存在盲区,尤其在公司主体发生重大变化如解散、收购时,虚拟股股东的失语处境使其无法得到应有的公允保护。而合同为主的路径过分强调了合同的可实现内容,所遮蔽掉的是变动不居的市场环境,信息不对称的先前存在,以及权利义务自由安排的可选择性。为此在后金融危机时代,针对虚拟股股东的保护路径也急需从二分法则的单边主义向碎片化的多元主义做以应时转化,还原虚拟股协议的劳动合同属性,比附优先股制度,在合同原则的统领下引入声誉资本等替代机制。
