| 摘 要： | 针对现有组合评价法只是对组合评价系统一个层面上问题的讨论,组合过于简单,缺乏系统性的问题,提出了一种基于综合评价方法属性层次的新的组合评价方法.首先,在误差的平方和的期望最小的意义下,构造最优化模型,在此基础上将差异度引进事后检验;其次,给出了最优化模型的证明;最后,用实例说明了此模型的有效性.

| Abstract: | The existing combination evaluation method only discusses the problem of combination evaluation system from one level,the combination is too simple and lacks of the systemic problem.So a new combination evaluation method is proposed based on the attribute hierarchical comprehensive evaluation method.Firstly,the optimization model is constructed under the significance of the smallest square error sum,and the difference degree is introduced to test afterward.Secondly,the optimization model is proved.Finally,the effectiveness of this model is explained by using examples. |
