遗传算法在网上谈判支持系统中的应用研究 总被引:12,自引:0,他引:12
从 8 0年代后期首次出现谈判支持系统至今 ,国外许多学者从不的角度对其进行了大量的研究 ,而国内在这方面的研究尚处于起步阶段 .网上谈判支持系统不仅要为谈判人提供方便的交流媒介 ,更要为其提供合理的协调解 ,以减少冲突 ,提高谈判的成功率 .目前 ,对于网上谈判支持系统中谈判解支持的研究 ,尚未取得重大突破 ,采用的方法仅仅局限于效用函数法、对策分析法以及国内近期研究出的基于兴趣点的选择方案搜索算法等等 .但是 ,这些方法在实际应用中很难方便、及时地为谈判人提供有效的建议解或方案支持 ,无法满足网上谈判的实际需求 .本文针对遗传算法的全局收敛性快速寻优、可并行性寻优以及模拟自然进化过程解决最优问题等特点 ,尝试着将遗传算法用于网上谈判支持系统中 ,为谈判人提供对于双方而言满意的协调解 ,对此 ,文中进行了一系列的理论分析及实践检验 ,证明了这种方法的可行性及特殊的优越性 . 相似文献

协商支持系统中的冲突协调方法 总被引:4,自引:0,他引:4
提出了一个协商支持系统的结构模型,用于在多方协商和谈判活动中促成一个满意、合理的协议。在协商出现冲突时,系统运用集对分析和物元分析的方法对各方的协商条件提出调整和转化的合理建议,即在对协商双方需求(要求)集所组成的同、容、反分析的基础上,发现冲突所在,同时发现潜在的可能促成协商成功的因素。然后运用物元变换的方法进行调整和转化,尽可能地达成满意的协议。 相似文献

新兴产业保护中的两产品关税谈判模型 总被引:3,自引:1,他引:2
用多目标规划与博弈论方法研究两国与两国产业(或缔约方双方与双方产业)的决策与竞争,建立了6个参与人的规划与博弈混合的多层次的两产品关税谈判模型,该模型包含3层次.上层是一个多目标规划模型,中层包含一个博弈模型,下层包含两个博弈模型.在给定满足模型假设条件的参数下对模型进行了求解与分析,并求出了模型的关税谈判均衡解.模型可用于政府制定关税决策,预测关税上限对国家与产业的影响。 相似文献

两级递阶软对策模型及其在冲突分析中的应用 总被引:2,自引:0,他引:2
Nigil Howard通过对亚对策的改进提出了软对策,但该理论仍基于效用进行分析。且没有涉及局中人个体偏好与整体偏好的不一致问题。本文的主要工作包括以下三个方面:一是将多维偏好分析技术与现有软对策模型结合起来.弱化原来要求局中人对所有可行结局排序的条件,使之在分析面向目标的冲突问题中显得更加方便;二是考虑到整体利益与局部利益的差异的普遍存在,且在局中人现有偏好结构下又常无法达到整体最优结局的问题,在冲突分析中引入整体协调人,给出一个二级递阶模型;三是借助个体偏好偏离度向量定量测度个体偏好与整体偏好的差异程度。最后结合一水资源冲突问题进行实证分析。 相似文献

分析基于收益分配的群决策冲突问题,应用改进的Hirshleifer冲突函数构建群决策冲突均衡模型,解出均衡模型的内部均衡解并进行解的分析,分析结果显示,群决策冲突过程中,决策双方的谈判力可以通过资源的投入来改变并以资源投入相等达到均衡;决策者的收益低于其机会成本时,决策者会退出决策群体,导致群决策失败. 相似文献

COMPARISON OF THE ANALYTIC NETWORK PROCESS AND THE GRAPH MODEL FOR CONFLICT RESOLUTION 总被引:2,自引:0,他引:2
1. Introduction A strategic conflict is a situation in which two or more decision-makers are to make a decision that affects issues they have different preferences about (Fang et al. 1993). Conflicts are one of the most characteristic attributes of human societies. Various forms of strategic conflict exist all around us, in areas such as environmental management, international rela-tions, economic competition, and relationships among individuals. Conflicts are studied in a wide range of disci… 相似文献

Conflict analysis approaches for investigating attitudes and misperceptions in the War of 1812 总被引:1,自引:0,他引:1
Formal systems engineering approaches to modeling misperceptions and attitudes are employed within the framework of the graph model for conflict resolution to systematically study the War of 1812 between the United States of America and Great Britain in order to provide enhanced insights into the causes of the war. More specifically, relational definitions for preferences, movements and stability concepts are defined for describing the attitudes and associated behavior of decision makers involved in a conflict. To capture misperceptions of decision makers in the War of 1812, attitudes are studied within the structure of a hypergame. Combining attitudes and misperceptions within the paradigm of the graph model furnishes the flexible analytical tool which demonstrates that misunderstanding of attitudes by Great Britain and the United States may have contributed to the outbreak of this nasty war. 相似文献

A formal methodology for analyzing the importance of weighing a decision maker’s attitudes in a conflict is introduced and applied to the problem of negotiating a fair transfer of a brownfield property. A decision maker’s attitudes are expressed in his consideration of his own preferences,as well as those of his opponents.Dominating attitudes are used to suggest that in a circumstance in which a decision maker takes into account multiple perspectives due to his attitudes,he may favor one perspective more heavily.The analysis of a brownfield acquisition conflict illustrates the types of insights that this methodology reveals. 相似文献

A hierarchical multiple criteria model for eliciting relative preferences in conflict situations 总被引:1,自引:1,他引:0
A multiple criteria decision analysis(MCDA) approach is designed for capturing the relative preference information of a decision maker involved in a conflict.More specifically,an MCDA approach based on the outranking method,ELECTRE III,is employed for ranking states or possible scenarios in the conflict from most to least preferred,where ties are allowed,for a decision maker according to his or her value system.To demonstrate how this preference elicitation methodology can be conveniently implemented in practice within the framework of the Graph Model for Conflict Resolution,it is applied to a real world water supply crisis which occurred in the town of North Battleford,located in the Canadian province of Saskatchewan. 相似文献

STRATEGIC DECISION MAKING FOR IMPROVED ENVIRONMENTAL SECURITY: COALITIONS AND ATTITUDES 总被引:5,自引:2,他引:3
The utilization of decision support systems which are flexible enough to handle information about cooperative behavior and
stakeholder attitudes are useful for analyzing complex social conflicts. One such conflict which arose from the redevelopment
of a private brownfield property in Kitchener, Ontario, Canada is examined using such a decision support tool. Specifically,
a formal model referred to as COAT which allows for the examination of conflicts with both coalition and attitude properties
is rigorously defined and then implemented within the framework of the Graph Model for Conflict Resolution in order that insights
may be gained on how the decision makers can reach win-win resolutions. 相似文献
