- Accurate DEA models of obtaining the highest and lowest efficiency score of each DMU are proposed firstly.As a result, an interval efficiency score of each DMU is gotten. 首先建立了求解每个DMU的最高效率值和最低效率值的确定型DEA模型,从而求得每个DMU的区间效率值。
- Interval Efficiency Score 区间效率值
- The efficiency score is a general indication of how much more output the virtual output maximizer could achieve. 效率值(efficiency score)是指虚拟产出最大仓库(virtual output maximizer)比本仓库所多产出的量。最佳值是1.;0。
- The efficiency score is a general indication of how close your operation is to the virtual input minimizer. 效率值代表你仓库的运作离虚拟投入最小仓库的接近程度。
- For example, an input minimizer efficiency score 0.85 indicates that the inputs could be reduced to 85% while maintaining the same, if not surpassing the current level of output. 例如,一个投入最小仓库的效率值是0.;85,意味者产出不超过现有水平的情况下,仓库可以减少投入到原来的85%25,而维持现有状况。
- Analyzing competition ability by DEA can not only get the relative efficiency score of every DMU objectively and reasonably, but also improve the performance of the non-effective, and elevate the reliability and efficiency of insurance companies. 而竞争的胜败主要在于各保险公司竞争力的强弱。 运用DEA方法来评价我国保险公司的竞争力,不仅能客观、合理地给出各保险公司的相对效率,还可以提供把非DEA有效的保险公司发展为DEA有效的保险公司的改进方案,为提高竞争力提供有力依据。
- Data Envelopment Analysis(DEA) previously developed by means of linear programming formulation can merely be used for measuring the relative maximal efficiency score for decision making units(DMUs) in either input oriented or output oriented way. 单目标的传统DEA只能从投入或产出角度测算决策单元的相对最高效率。
- Then extends the efficiency measurement to the stochastic situation based on the expected value approach and presents the definition of the expected efficiency score, and finally a instance is given. 进一步提出了随机条件下决策单元的期望有效性指数概念和相对有效性评价的期望值方法,最后给出了计算实例。
- For example, an output maximizer efficiency score 1.25 indicates that the output level could be increases to 125% while consuming the same amount, or even less, of the input resource. 例如,产出最大仓库的效率值是1.;25意味着消费同样甚至更少的投入资源,产出水平还可以再提高到原来的1
- We formulate a CCR model with an interval efficiency which consists of efficiencies obtained from the cross efficiency, then all the DMUs are ranked by an interval ranking approach. 基于交叉效率方法,本文得出了决策单元的区间效率值并进行了排序。
- In the fuzzy DEA model whose inputs and outputs are fuzzy and efficiency score is precise, all DMUs could not be ranked when the number of efficient units is no less than two. 摘要在输入、输出数据为模糊数而效率值为准确值的模糊DEA模型中,会出现有两个以上有效单元,从而无法对所有决策单元进行全排序的情形。
- The second stage, we use efficiency scores as explained variable and environmental variable as explainable variable, than calculate slack variable. 第二阶段以投入变数作为被解释变数,利用环境变数为解释变数,计算差额变量;
- Latecomers will not be admitted until the interval. 迟到者在休息时间方可入场。
- A brief, indefinite interval of time. 瞬间一个短暂的、不确定的时间间隔
- Maybe he is a little less efficient scoring wise, but thats nitpicking. 可能得分方面效率降低了,不过这算挑剔。
- There is an hour's interval to the next train. 下一火班车还要过一小时才开。
- Because equilibrium among indicator scores is important for research evaluation, the author then corrected the efficiency scores of the universities with an extremely high ratio of its efficiency score to its total score based on a certain rule. 由于各指标得分的均衡程度是科研评价中的一项重要内容,因此作者接着对效益得分占总得分过高的部分高校的效益得分进行了基于一定规则的修正,并给出了修正后的高校人文社会科学研究竞争力评价结果。
- We had a quick drink in the interval. 我们在中间休息时匆匆喝了点东西。
- We changed seats in the interval. 中间休息时,我们交换了一下座位。
- A minor key, scale, or interval. 小调音、短音阶或短音程
