基于敏感性分析的房地产风险投资多目标决策 总被引:1,自引:0,他引:1
房地产风险投资决策是复杂的多目标决策问题,针对其评价指标的属性随项目发展可能的动态变化,提出运用向量夹角余弦建立指标客观性权重给出初始最优选择方案,并运用权重敏感性分析的思想对其进行后最优性分析,最终给出最优方案排序发生变化的指标权重临界值的方法来处理房地产风险决策的多指标评价问题,并通过一个实例指出此类方法应用的可行性。 相似文献

关于银行竞争力评价在上个世纪80年代就已起步,我国95年开始加入这个评价体系。现有的评价体系主要是指标法,即通过对不同的指标加权平均而对银行进行排名。对于不同指标的权重的选择没有统一的方法。数据包络分析方法(DEA)作为处理多个决策单元的多投入、多产出的非参数统计方法.已经在多个领域得到了广泛的应用.但用于银行业的评价分析还很少。本文尝试运用DEA方法对中国银行业运行状况进行有效性评价分析,研究各个银行的投入与产出比是否有效率,这也是DEA评价方法和模型应用的一个新的尝试。本文同时选择不同年份的数据对我国银行业做了一个DEA跟踪分析。 相似文献

VMI环境下制造商与供应商之间的合作竞争过程中存在着知识转移,基于此本文构建了VMI供应商评价指标体系。运用GAHP集中多位专家的决策经验,确定各评价指标的相对重要性;使用聚类分析算法,对已经预处理的大量供应商样本数据进行分类,同时根据分类及指标权重评定等级,减少被评方案,再用GAHP进行选择。最后通过一个例子说明所使用的方法在VMI供应商选择中具有准确、快速且有效的特点。 相似文献

The existing multiple attribute group decision-making approaches based on intuitionistic fuzzy sets (IFSs) or interval-valued intuitionistic fuzzy sets (IVIFSs) are considered as the situation that the weights of experts are given beforehand and the attribute weights are known or unknown. To better describe the uncertain decision environment and solve the corresponding decision problem, multiple attribute group decision-making methods with completely unknown weights of both experts and attributes are proposed in intuitionistic fuzzy setting and interval-valued intuitionistic fuzzy setting. Entropy weight models can be used to determine the weights of both experts and attributes from intuitionistic fuzzy decision matrices or interval-valued intuitionistic fuzzy decision matrices, and then the evaluation formulas of weighted correlation coefficients between alternatives and the ideal alternative are introduced in intuitionistic fuzzy setting and interval-valued intuitionistic fuzzy setting. The alternatives can be ranked and the most desirable one(s) can be selected according to the values of the weighted correlation coefficients for IFSs or IVIFSs. Finally, two numerical examples demonstrate the effectiveness of the proposed methods: they are capable for handling the multiple attribute group decision-making problems with completely unknown weights. 相似文献

基于重要性的顾客满意度指数的测评 总被引:3,自引:0,他引:3
顾客满意度自20世纪80年代从美国引用到中国以来,在中国得到了快速推广和应用。目前学术界根据顾客满意度指数的基本概念,分析了顾客满意度指数测评指标体系,提出了基于重要性的顾客满意度指数的测评方法。该方法根据模糊聚类技术与粗糙集中的相对正域理论,从测评数据中根据属性重要性确定各属性的权重,依此来计算顾客满意度指数。 相似文献

考虑评价环境的复杂不确定性、评价专家的信任行为特征以及群组专家的共识等问题,提出了一种区间Fermatean模糊信任网络群组综合评价方法。首先,针对区间Fermatean模糊评价信息的集成问题,提出了区间Fermatean模糊信息的运算规则,并在此基础上提出了一种区间Fermatean模糊Frank集成方法。其次,考虑到评价专家间信任关系对专家权重和共识达成的影响,构建了基于语言术语的信任网络以计算专家权重,同时设计了个性化反馈机制,进而构建了信任共识交互模型以提高群组共识度。此外,针对评价指标权重未知的情形,提出了区间Fermatean模糊熵权法获取指标权重。最后,通过高校商科类本科生统计设计能力的评价问题验证所提出方法的可行性和优越性。 相似文献

Identifying risks and prioritizing is important for payment service provider (PSP) companies to get banking projects and gain more market share. However, studies regarding the identification of risks and causal relationships are insufficient in the Iranian PSP industry and the industry is unique because of its characteristics. In this study, 30 experts involved with PSP companies are employed as the research sample. Eleven key risks and Forty-six sub-risks are also identified. Subsequently, the fuzzy decision-making trial and evaluation laboratory technique is applied to determine the effective and affected risks and the severity of their effects on each other. Finally, all risks are ranked. Due to the internal interrelationships of the main risks, the weight of each risk is calculated via the fuzzy analytic network process. As the second-level risks have no significant interrelationships, they are ranked via the fuzzy analytical hierarchy process. Moreover, the best-worst method is used to ensure that the obtained rankings are reliable. This study identifies the risks affecting the loss of banking projects and determines the impacts of these risks on each. A sensitivity analysis is then conducted on the weights of the criteria, and the results are compared. 相似文献

In this paper, a kind of multiple attribute group decision making problem is studied, where there is no original information about the weights of importance of the attributes and the decision makers (DMs), and the attribute values are given in the form of interval-valued intuitionistic fuzzy numbers (IVIFNs). To solve this problem, a new method is proposed based on utility theory. In the proposed method, the weights of importance of the DMs and the attributes are all determined by using the intuitionistic indexes of related IVIFNs. And then, the alternatives are compared by using their composite interval indexes which are generated based on utility theory. Finally, two numerical examples are proposed to demonstrate the effectiveness of the proposed method. 相似文献

Hesitancy is the most common problem in decision making, for which hesitant fuzzy set can be considered as a suitable means allowing several possible degrees for an element to a set. In this paper, we study the aggregation of the hesitancy fuzzy information. Several series of aggregation operators are proposed and the connections of them are discussed. To reflect the correlation of the aggregation arguments, two methods are proposed to determine the aggregation weight vectors. Based on the support degrees among aggregation arguments, the weight vector of decision makers are obtained more objectively. To deal with the correlation of criteria, we apply the Choquet integral to get the weights of criteria. A method is also proposed for group decision making under hesitant fuzzy environment. 相似文献
