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。Sections 1 through 3 of the full pater explain our algorithm mentioned in the title, which we believe is new and better and whose core consists of： ＂In order to overcome the subjective limitation in traditional grey evaluation, a new model for comprehensive evaluation, i. e. , entropy weight comprehensive evaluation model, was established; the modified weight values corresponded to different evaluation indexes. And the model was applied to evaluating the performance of embedded computer. All kinds of factors having influence on embedded computer performance were established and the weight of each factor was calculated objectively with an entropy weight-based coefficient method combined with analytic hierarchy process. ＂ Finally, an empirical analysis, presented in section 4, demonstrates preliminarily that our model avoided the drawback of the traditional grey evaluation, whose subjectivity is relatively strong, thus showing that our model is indeed more effective.
