| 摘要: |
| 为了克服传统的灰色综合评判中主观赋权的局限性,借鉴信息熵的思想,提出了熵权确定权重的方法,构造了基于熵权法的灰色综合评价模型,该模型运用熵权法和层次分析法相结合确定各个因素的权重系数,利用灰色评估原理和方法进行定量分析,并将该模型应用到嵌入式计算机性能评价模型中。案例表明,该方法避免了传统灰评估方法的主观性太强,使灰评估模型既具有客观性,同时具有专家的经验判断,提高了嵌入式计算机性能评估的可靠性,为嵌入式计算机性能综合评价提供了新方法。 |

| Abstract: |
| Sections 1 through 3 of the full pater explain our algorithm mentioned in the title, which we believe isnew and better and whose core consists of:"In order to overcome the subjective limitation in traditional grey evalua-tion, a new model for comprehensive evaluation, i.e., entropy weight comprehensive evaluation model, was estab-lished; the modified weight values corresponded to different evaluation indexes.And the model was applied to eval-uating the performance of embedded computer.All kinds of factors having influence on embedded computer per-formance were established and the weight of each factor was calculated objectively with an entropy weight-based co-efficient method combined with analytic hierarchy process.".Finally, an empirical analysis, presented in section4, demonstrates preliminarily that our model avoided the drawback of the traditional grey evaluation, whose subjec-tivity is relatively strong, thus showing that our model is indeed more effective. |
