在合作博弈中,Shapley单点解按照参与者对联盟的边际贡献率对联盟的收益进行分配.联盟收益具有不确定性,往往不能用精确数值表示,更多学者关注特征函数取值为有限区间的合作博弈(区间合作博弈)的收益分配.文章利用矩阵半张量积,研究区间合作博弈中含有折扣因子的Shapley区间值的矩阵计算.首先利用矩阵的半张量积将合作博弈的特征函数表示为矩阵形式,得到特征函数区间矩阵.然后通过构造区间合作博弈Shapley矩阵,将区间合作博弈的Shapley值(区间)计算转化为矩阵形式.最后利用区间合作博弈Shapley值矩阵公式计算分析航空公司供应链联盟收益的Shapley值.文章给出的区间合作博弈Shapley值的矩阵计算公式形式简洁,为区间合作博弈的研究提供了新的思路. 相似文献

针对具有模糊联盟且支付值残缺的合作对策问题,给出了E-残缺模糊对策的定义.基于残缺联盟值基数集,提出了一个同时满足对称性和线性性的w-加权Shapley值公式.通过构造模糊联盟间的边际贡献,探讨了w-加权Shapley值公式的等价表示形式,指出w-加权Shapley值与完整合作对策Shapley值的兼容性.在模糊联盟框架里,探讨了w-加权Shapley值所满足的联盟单调性、零正则性等优良性质.最后通过算例验证了该公式的有效性. 相似文献

区间合作对策,是研究当联盟收益值为区间数情形时如何进行合理收益分配的数学模型。近年来,其解的存在性与合理性等问题引起了国内外专家的广泛关注。区间核心,是区间合作对策中一个非常稳定的集值解概念。本文首先针对区间核心的存在性进行深入的讨论,通过引入强非均衡,极小强均衡,模单调等概念,从不同角度给出判别区间核心存在性的充分条件。其次,通过引入相关参数,定义了广义区间核心,并给出定理讨论了区间核心与广义区间核心的存在关系。本文的结论将为进一步推动区间合作对策的发展,为解决区间不确定情形下的收益分配问题奠定理论基础。 相似文献

首先,将经典合作博弈进行扩展,提出了一类模糊联盟合作博弈的通用形式,涵盖常见三种模糊联盟合作博弈,即多线性扩展博弈、比例模糊博弈与Choquet积分模糊博弈.比例模糊博弈、Choquet积分模糊博弈的Shapley值均可以作为一种特定形式下模糊联盟合作博弈的收益分配策略,但是对于多线性扩展博弈的Shapley值一直关注较少,因此利用经典Shapley值构造出多线性扩展博弈的Shapley值,以此作为一种收益分配策略.最后,通过实例分析了常见三类模糊联盟合作博弈的形式及其对应的分配策略,分析收益最大的模糊联盟合作对策形式及最优分配策略,为不确定情形下的合作问题提供了一定的收益分配依据. 相似文献

The Shapley value, one of the most widespread concepts in operations Research applications of cooperative game theory, was
defined and axiomatically characterized in different game-theoretic models. Recently much research work has been done in order
to extend OR models and methods, in particular cooperative game theory, for situations with interval data. This paper focuses
on the Shapley value for cooperative games where the set of players is finite and the coalition values are compact intervals
of real numbers. The interval Shapley value is characterized with the aid of the properties of additivity, efficiency, symmetry
and dummy player, which are straightforward generalizations of the corresponding properties in the classical cooperative game
theory. 相似文献

An independent set game is a cooperative game dealing with profit sharing in the maximum independent set problem. A population monotonic allocation scheme is a rule specifying how to share the profit of each coalition among its participants such that every participant is better off when the coalition expands. In this paper, we provide a necessary and sufficient characterization for independent set games admitting population monotonic allocation schemes. Moreover, our characterization can be verified efficiently. 相似文献

Uncertainty is a daily presence in the real world. It affects our decision making and may have influence on cooperation. Often
uncertainty is so severe that we can only predict some upper and lower bounds for the outcome of our actions, i.e., payoffs
lie in some intervals. A suitable game theoretic model to support decision making in collaborative situations with interval
data is that of cooperative interval games. Solution concepts that associate with each cooperative interval game sets of interval
allocations with appealing properties provide a natural way to capture the uncertainty of coalition values into the players’
payoffs. This paper extends interval-type core solutions for cooperative interval games by discussing the set of undominated
core solutions which consists of the interval nondominated core, the square interval dominance core, and the interval dominance
core. The interval nondominated core is introduced and it is shown that it coincides with the interval core. A straightforward
consequence of this result is the convexity of the interval nondominated core of any cooperative interval game. A necessary
and sufficient condition for the convexity of the square interval dominance core of a cooperative interval game is also provided. 相似文献

The existence of a Nash-stable coalition structure in cooperative games with the Aumann–Dreze value is investigated. Using the framework of potential functions, it is proved that such a coalition structure exists in any cooperative game. In addition, a similar result is established for some linear values of the game, in particular, the Banzhaf value. For a cooperative game with vector payments, a type of stability based on maximizing the guaranteed payoffs of all players is proposed. 相似文献
