项目融资是一种新兴的融资模式,是适用于基础设施项目的一种重要筹资手段。由于项目融资的实现过程是一个存在着很大不确定性的过程,因此投资者必然承担较大的风险。分析了项目融资风险的来源并运用不确定决策理论建立区间数多属性评价模型,对项目融资风险进行定量分析,为投资者在选择项目时进行科学的投资决策提供参考。 相似文献

A Generic Framework for Automated Multi-attribute Negotiation 总被引:1,自引:0,他引:1
Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides
an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes
the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute
negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete
information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation
with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work. 相似文献

城镇化是当前中国的一项重要发展战略,城镇化水平是衡量一个国家或地区城镇化状况的重要指标。影响城镇化水平的因素众多,在这些众多的影响因素中有些因素具有模糊性和随机性,本文采用区间多属性评价方法对中国城镇化水平进行评价,试图充分考虑这些模糊信息和随机信息,更加全面地反映一个地区的城镇化水平。 相似文献

Multi-attribute negotiation is an important mechanism for distributed decision makers to reach agreements in real-world situations. It allows the possibility of reaching “win-win” solutions for both parties, who trade off different attributes in a solution. Existing research on multi-attribute negotiations has mainly focused on the situations when negotiation parties have complete information about each other's preference. This paper presents a model with incomplete information, while considering Pareto-efficiency and computational efficiency. A non-biased mediator, who applies query learning to maintain near Pareto-efficiency without heavy computation, is adopted in the model. In addition, the mediating mechanism proposed in the model overcomes the difficulty of preference elicitation which usually arises in the preliminary step of a multi-attribute negotiation. Our model also reduces the negotiation complexity by decomposing the original n-dimensional negotiation space into a sequence of negotiation base lines. Agents can negotiate upon a base line with rather simple strategies. The experimental results show that near Pareto-efficient agreements can be reached effectively. 相似文献

在多属性决策优化问题中,往往存在很多不确定信息。本文针对不确定的属性权重,在前人研究的基础上,将专家的主观权重和来自物理学的熵权相结合,产生新的不确定多属性决策问题权重确定方法。介绍相关概念,提出结合的方案,并论证新方法的可行性。 相似文献

一种产品服务系统商业模式择优方法 总被引:1,自引:0,他引:1
提出了一种基于形态学矩阵和二元语义多准则妥协优化解(VIKOR)方法的产品服务系统(product-service system,PSS)商业模式方案开发、评价和选择的系统性方法。在分析PSS类型特征及其商业模式元素的基础上,通过形态学矩阵组合设计来获得可行的PSS商业模式待选方案;在确定PSS商业模式方案决策层次模型的基础上,采用综合考虑主、客观权重的二元语义VIKOR方法,对PSS商业模式方案进行多属性群决策。最后,通过实例说明了该方法的可行性和实用性。 相似文献
