层次分析法(Analysis Hierarchy Process 简称AHP)是由Saaty教授在20世纪70年代提出的一种对非定量事件处理的多目标决策方法,该方法的关键步骤是构造判断矩阵,其量化通常采用1-9标度,有时由于决策者对事物认识的多样性以及客观事物的复杂性,从而使不同决策者对决策对象有不同的偏好,给出的判断矩阵不能很好地反映实际,这样就出现了"不确定性". 相似文献

本文结合模糊的定义阐述了如何构造模糊一致判断矩阵,并进一步构造符合一致性要求的互反判断矩阵从而计算排序向量的方法。此法具有不需要再对判断矩阵进行一致性检验,因素两两比较时不需要具体表示出优或劣的程度,用方根法求取的排序向量不存在误差等优点,并且计算过程清晰、合理。在此基础上,本文将此法运用于供应商选择问题,开发出了供应商选择决策支持系统。 相似文献

上海世博会影响力定量分析是一种社会经济系统的决策分析问题,目前解决这类问题主要有层次分析法、模糊相似选择法、模糊聚类分析法、模糊层次法、模糊综合评判法等.以层次分析法为例,它是一种多层次权重分析决策方法.它既包含定量的计算,又包含定性的分析,具有高度的逻辑性、系统性和实用性.现在,层次分析法已经广泛运用.其关键环节是建立判断矩阵,判断矩阵是否合理、科学直接影响到它的应用效果.但层次分析法在应用中有几点不足:一是判断矩阵的一致性与人类思维的一致性有差异;二是检验判断矩阵的一致性比较困难;三是当判断矩阵不具有一致性时,调整成一致性比较麻烦;四是检验判断矩阵一致性的判断标准(CR<0.1)缺乏科学的依据.而FAHP(模糊层次分析法)可以克服以上不足,是-种比传统层次分析法更科学、更简便的方法.本文便运用此方法结合模糊综合评判法进行定量分析. 相似文献

在多属性大群体决策环境下,针对决策者给出关于决策方案两两比较且可能包含残缺值的模糊偏好关系的决策问题,提出了一种基于相似度聚类的残缺值模糊偏好关系大群体决策方法。此方法首先通过标准化残缺值矩阵,然后定义判断矩阵之间的相似度对大群体进行聚类,再对各个属性下的群体偏好进行集结,通过偏差熵模型确定各个决策属性的权重,集结所有决策属性下的群体偏好,最后得到决策方案的排序结果。文章最后给出了一个算例分析以验证此方法的有效性。 相似文献

基于AHP—Fuzzy算法的供应链合作伙伴选择研究 总被引:1,自引:0,他引:1
AHP—Fuzzy评价方法是一种将AHP方法和模糊数学相结合的评价方法。AHP能综合人的主观定性判断,形成各个决策因素的权重,避免在结构复杂的决策问题上出现逻辑推理失误。模糊数学通过模拟人类做判断的特点,善于处理不精确的、模棱两可的信息。因此,AHP—Fuzzy将层次分析法和模糊评价方法结合起来,能够取长补短,使决策更具科学性。并以供应链合作伙伴的选择为例。 相似文献

One of novel manners to achieve sustainable development is concentrating on circular economy in order to manage greenhouse gas emissions, energy consumption, and waste. It also helps to protect the environment and optimize usage of input resources. The main element of circular economy is closed-loop supply chain which covers both forward and reverse products flows. This study aims to outsource logistics operations in a closed-loop supply chain. An innovative analytical multi-step fuzzy decision-making method is proposed to rank sustainable third-party logistics service providers (3PLSPs). Fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) is first used to evaluate the relationships among the main criteria. Then, fuzzy analytic network process (ANP) is applied to weight the determined set of criteria. In order to develop the hybrid fuzzy DEMATEL-ANP method and to simplify the computation, the expert judgment method is used between the two techniques as a middle step to reduce the number of criteria. As many of the criteria overlap with each other on content and context, expert opinions are used to shortlist and rank the criteria. Finally, the 3PLSPs are ranked through the fuzzy complex proportional assessment (COPRAS) method. To validate the practicability and applicability of the improved decision-making model, a household appliance case study is applied with data obtained from industry experts. In this case, five service providers are considered and ranked, while the first one gets the best score. A sensitivity analysis is performed by altering the criteria weights to validate the proposed approach, data, and the obtained results. In terms business and the environment, this study provides success critical criteria for decision-making problems in circular economy for addressing sustainable development. 相似文献

Quality function deployment (QFD) has been developed by Toyota Motor Corporation in order to reduce time and shorten design
times. QFD is composed of a set of matrices referred to as the house of quality (HOQ). A HOQ matrix can help the cross-functional
team to translate customer requirements (CRs) into engineering goals. The importance of CRs and the relationships between
CRs and technical characteristics (TCs) are obtained by a group of people with vague and fuzzy decision-making processes in
the HOQ. In the conditions, a group decision-making method by using the combination of fuzzy set theory and genetic algorithms
(GAs) can be used in QFD to determine the importance of each TC. Besides, a numerical example is illustrated to show that
this group decision-making method by using the combination of fuzzy set theory and GAs can be reliably and precisely applied
in QFD including TCs at the two-level hierarchy with the consideration of some constraints regarding budget and time limits
of TCs for prioritizing TCs to effectively make decisions with fuzziness and ambiguousness. 相似文献

Owing to the complexity of a construction project, the fuzzy ANP is helpful to deal with interdependent relationships within
a multi-criteria decision-making model. This paper uses the Porter’s diamond model that influences how competitive advantages,
which is a matrix providing a conceptual model for the main framework, as a construct for selecting the location of a regional
hospital in Taiwan to determine its effectiveness. The applicability of our proposed fuzzy ANP model is demonstrated with
a case study that summarizes an intervention in which the model’s framework and basic concepts were applied. 相似文献
