在多属性决策问题的求解过程中,大部分多属性决策方法都涉及到属性权重的确定问题.一般可分为主观赋权法和客观赋权法.为兼顾决策者对属性的偏好,同时又力争减小赋权的主观随意性,进而使决策结果更加客观、可靠,本文以层次分析法为基础提出一种主、客观细合赋权方法.该方法基于属性值的规范化决策矩阵和决策对方案近似估计的区间判断矩阵,提出一种模糊线性规划方法确定属性权重.  相似文献

上市公司的经营业绩是股东、债权人和公司员工关注的重要问题,如何正确、公允的评价上市公司的经营业绩,成为财务分析人员的重要工作.目前,对上市公司业绩评价方法主要有单指标法和多指标法.单指标法不能反映特定企业的综合水平,片面性强;多指标法需要对每个指标进行赋权,赋权方法有主观赋权和客观赋权两种.主观赋权主要是通过定性分析分析各指标的相对重要性,这在指标比较少时或许还可行,但当指标比较多时,确定各指标间的相对重要性就有很大的困难,另外主观赋权主观性太强,同样的数据,不同的人会得出不同的结果,因此这种方法在使用上具有局限性.客观赋权主要是运用定量的方法给各指标一定的权数,主要有熵值法、DEA法、因子分析法等.本文根据因子分析法的原理,构建了基于因子分析法的经营业绩评价模型,并以河北省上市公司为对象展开实证研究,为企业经营业绩评价提供有益的探索.  相似文献

熵值法是一种客观赋权方法,它通过计算指标的信息熵,根据指标的相对变化程度对系统整体的影响来决定指标的权重,相对变化程度大的指标具有较大的权重,此方法现广泛应用在统计学等各个领域,具有较强的研究价值。但随着社会的发展、科学的进步及我们研究问题的复杂性越来越高,传统的熵值法已经不能完全满足研究的需要,这样就有必要对它进行一定的改进。本文就针对此问题进行了初步探索,并对改进的熵值法和其它客观赋权法的进行了比较。  相似文献

为提高传统网络风险评估方法的准确性,针对大部分网络风险评估方法未考虑攻击能力值的问题,提出了一种基于项目反应理论的实时网络风险评估方法。该方法利用项目反应理论引入的攻击能力值参数以及服务安全等级参数,对传统攻击威胁值和攻击成功概率计算方法进行改进,并采用三标度层次分析法构建出更准确的服务重要性权重,最终获得符合网络环境的评估态势。仿真结果表明:该方法可以提高评估结果的准确度,并实时地绘制更符合真实网络环境的安全态势图。  相似文献

We propose a group decision making model based on conflicting bifuzzy sets (CBFS) where evaluation are bi-valued in accordance to the subjective assessment obtained from the experts for the positive and negative views. This paper discusses the weighting methods for particular attribute and subattribute with emphasis given to the unification of subjective and objective weights. The integration of CBFS in the model is naturally done by extending the fuzzy evaluation in parallel with the intuitionistic fuzzy. We introduce a new technique to compute the similarity measure, being the degree of agreement between the experts. We end up the paper by demonstrating the applicability of the proposed model to the empirical case of flood control project, one of the project selection problems.  相似文献

In this article, we investigate group decision making problems with interval multiplicative preference relations (including complete interval multiplicative preference relations and incomplete interval multiplicative preference relations). On the basis of the number of judgments and the consistency degree of each interval multiplicative preference relation, we first give a combined weighting method to derive the weights of decision makers. Then, we establish two linear programming models to derive the weight intervals of alternatives from all individual consistent interval multiplicative preference relations and utilize the continuous ordered weighted averaging operator or the continuous ordered weighted geometric operator to aggregate all the values in each weight interval. In addition, we establish a more general model to check the consistency of all individual interval multiplicative preference relations. In the cases where the optimal objective value of the model is not zero, we can get the optimal weights of alternatives directly, and then utilize these optimal weights and the optimal deviation values derived from the model to construct consistent interval multiplicative preference relations. Furthermore, we discuss some special cases of the established models and illustrate our models with a practical example.  相似文献

结合J公司采购现状,针对J公司供应商评价指标体系与方法的不足,采用改进层次分析法的逼近于理想解的排序法综合评判方法,对J公司的供应商评价体系和择优进行相关研究,最后得出了各指标体系的权重。其中,质量、成本、技术、配件及服务和供货这4项指标所占权重最大,而管理文化和安全权重则较低。这与J公司的现有评价指标的设置基本相符。为了公司可持续性发展,公司研究决定将指标体系加入管理文化评价以及安全所评价。公司还成立了专门的部门———安全部,不仅负责本公司的安全评估,也负责供应商的安全评估,并由采购物流部负责供应商管理文化的定期评估。  相似文献

Although there is immense international support for consumer protection, the notion exists that consumer protection can only exist in developed countries with ample fiscal resources and expertise to properly act in the interest of consumers. This conception leaves consumers in emerging and transitional economies in a difficult position as these economies indeed generally lack sufficient funding and the required capacity to educate consumers on their rights. With the South African Consumer Protection Act that came into effect in 2011, South African consumers can now claim to be among the best protected consumers in the world. However, many consumers are still not aware of their consumer rights, and do not have the necessary knowledge to pursue redress when they are dissatisfied. The objective of this research was therefore to explore and describe the relationship between consumers’ knowledge of consumerism (consumer protection) and their consumer complaint behaviour (CCB) concerning their dissatisfaction with a technologically advanced product, in this case, a consumer electronic product. This study attempts to differentiate between subjective consumerism knowledge and objective consumerism knowledge and by extension the measures used. In addition, we explored and described the relationship between demographic variables and levels of subjective and objective consumerism knowledge as well as the combined effect of the two types of knowledge on CCB. The findings revealed that the respondents had a reasonable level of subjective consumerism knowledge relative to a low level of objective consumerism knowledge. No significant relationship was found between subjective consumerism knowledge and demographic variables. However, the factors of race, gender and level of income were related to objective knowledge. A higher level of subjective knowledge could be associated with public action. Respondents with reasonable levels of objective knowledge were also better equipped to take private and public action. CHAID (Chi‐Square Automatic Interaction Detection) analysis highlighted that a combination of subjective and objective knowledge was the best predictor of taking public action only and of taking both private and public complaint action. The study has implications for policy makers, consumer protection organisations, retailers and the individual consumer. Our approach to measuring knowledge of consumerism could possibly be applied in other emerging contexts where consumers generally lack awareness of consumer protection.  相似文献

The structural alignment literature suggests that people place more weight on alignable (vs. nonalignable) attributes when evaluating competing options. The present research proposes that consumers' regulatory orientation moderates this process. Specifically, consumers differentially weight alignable versus nonalignable attributes depending on whether they are prevention or promotion-oriented. Results of four studies indicate that prevention-oriented consumers who tend to construe information at a more concrete level rely more on alignable attributes when evaluating two options as compared to promotion-oriented consumers who tend to construe information at a more abstract level, and are influenced more by nonalignable attributes. The authors further show that consumers' construal level and differential ease of processing the two types of attributes mediate the influence of regulatory orientations on their relative weighting of alignable versus nonalignable attributes and product evaluations.  相似文献

We formulate, estimate, and analyze a model of consumer response to promotions where consumers' receipt of the promotional reward is uncertain. The model incorporates consumers' risk aversion and their subjective assessment of the probability that they will get the reward. It is used to assess the effectiveness of a “conditional rebate”, where the uncertainty arises because the reward is contingent on an external event, versus a traditional rebate, which is similar in all respects except that it is certain. We estimate the model using a conjoint choice experiment. Response to conditional rebates is highly segmented and related to perceived thinking costs and savings and entertainment benefits of conditional rebates as well as to event involvement and gambling proneness. In our application, conditional rebates are more cost effective than certain rebates, mostly because consumers' subjective probability of the event occurring is higher than what market wisdom suggests.  相似文献
