基于多目标优化的供应商绩效评估

考虑到供应商绩效评估指标体系的多目标性,给出了一种基于可行域为有限集的多目标问题的优序解法和改进优序法,快速有效地对评估方案进行排序为决策提供依据.     

冲突多目标相容预测控制

两层结构的相容控制框架可以解决复杂冲突多目标控制问题,但其需要克服的困难是多目标直接优化、第一层所选区间目标的实现和在线实时优化控制。采用多目标遗传进化算法解决了直接优化多目标的工具问题。为能实现第一层中所选择的控制目标,第二层中设计了不同于第一层中形式的指标,并加入选择函数以反映实际系统的需要。结合预测控制思想的特点,提出了在线迭代遗传算法,解决了在线优化速度问题。以预测控制动态过程中误差、能耗两个目标为例对相容预测算法进行了说明。     

区间值信念结构下冲突证据组合

区间值信念结构下证据理论在信息融合、决策分析中有着广泛的应用前景.针对区间值冲突证据组合出现反直观结果问题,提出一种新的证据组合方法.从整体角度构建证据间Pignistic概率距离的最优化模型,通过得出的相对权重来修正证据, 使之符合Dempster组合规则可用范围,然后组合. 算例分析表明所提方法是合理有效的.     

一种基于神经模糊系统的协商策略

协商策略是自治协商的关键环节之一。针对现有协商策略受限于Nash理论的不足,提出一种由模糊逻辑与神经网络深度融合的神经模糊系统(NFS)的协商策略。分析了这两种计算智能技术的协同机制,引入了广义概率积与广义概率和模糊算子,给出了网络有关参数的学习式子。实验结果表明,NFS是有效的,具有较好的性能;基于NFS的协商策略符合人类协商的思维和常规,能获得更高的协商收益和协商效率。     

A Fuzzy Negotiation Model of E-commerce

We usually decide to accept or reject the offer based on the utility function in the traditional automatic negotiation of E-commerce so that we reject the offers whose utility is lower than a specified value. Here we evaluate the acceptability based on the fuzzy set theory and the membership function. Since different issues have different effect on the negotiators, we state the combined concession in the multi-issue negotiation for the negotiators. We put forward a more practical negotiation model than the traditional negotiation model and give an example of its application in E-commerce.     

Web Services Composing by Multiagent Negotiation

Composing web services is gained daily attention in Service Oriented Computing. It includes the dynamic discovery, interaction and coordination of agent-based semantic web services. The authors first follow Function Ontology and Automated Mechanism Design for service agents aggregating. Then the problem is formulated but it is ineffective to solve it from the traditional global view. Because the complexity is NP-complete and it is dii~cult or even impossible to get some personal information. This paper provides a multi-agent negotiation idea in which each participant negotiates under the condition of its reservation payoff being satisfied. Numerical experiment is given and well evaluates the negotiation.     

Negotiation,Management, and Systems Thinking

The mutual apartness of negotiation, management, and systems thinking and practice is highlighted, and a reflection on a systemic view of negotiation is presented. An overview of negotiation studies is given, as well as practical comments on the pursuit of win-win to achieve the general satisfaction of the parties and lasting relationships; the importance of everybody's participation; different views and facets of negotiation and of conflict; the basic variables of power, time, and information; and the basic points for a methodic negotiation process. Some aspects of negotiation have been selected from the management literature. Systems approaches that could contribute to negotiation and benefit from its findings are recalled, integrated into TSI/ LSI, which seems to offer a conceptual and procedural guide to a systemic view of negotiation as a wheel for management, as suggested in the final section.     

新不确定度量下的冲突证据融合

针对证据高度冲突的情况下,DS证据理论在实际应用中出现错误融合结果的问题,提出基于不确定度的冲突解决方法.首先分析现有的不确定度量方法的不足,研究基本概率赋值本身所包含的信息,提出一种新的对证据不确定性度量的方法;依据新的不确定度量,结合证据距离生成权重来修正待组合证据体,再利用Dempster规则完成证据组合,可有效解决证据高度冲突情况下的信息融合问题,最后通过算例验证了该方法的有效性.     

谈判支持系统研究综述

针对谈判支持系统(Negotiation Support Systems,NSS)研究中的几个基本问题进行了分析和评述,包括谈判的定义、谈判行为理论模型、谈判问题的研究方法、NSS的起源和发展、NSS的研究方向等.并根据目前的发展现状,分析了NSS体系结构,提出了NSS未来的发展模式和配置方案.     

面向动态联盟协商支持的研究

动态联盟已经成为企业实施敏捷制造的重要手段。在动态联盟构建，实施及解体的整个生命周期中，存在着很多决策问题，需要各联盟企业共同协商解决。本文分析动态联盟中多方协商的特点，基于多人多目标协商对策理论对多方协商机制进行了数学描述，给出最大均衡满意度协商对策解的定义，提出一种满足Pareto最优的最大均衡满意度协商对策解的求解方法。     

解决冲突的图形模型在谈判支持系统中的应用
