基于熵值法赋权的新灰色关联度量化模 型简

本文在已有灰色关联理论的基础上，简要阐述了现有的几种典型灰色关联度量化模型，并分别指出了其在比较序列变化率上的缺陷。在此基础上，提出了一种基于熵值法赋权的灰色关联度量化模型。模型主要考察了序列变化率的差异，尤其对于序列间细微差异有较强分辨能力，关联度取值更能被直观接受，并采用熵值法进行权重分配，序列变化中离散程度大的折线段因熵值较大赋予的权重相对较小，因此更能平衡地体现序列间的差异，并将其反映到关联度值中。

Novel Grey Incidence Computation Model Based on Entropy Method

Based on the theories of Grey incidence theory, this paper summarizes several representa- tive Grey incidence computation models of present and points out their indications in the sequence change rate respectively. On this foundation, a new Grey incidence computation model based on entropy method is proposed. The modle mainly studies the differences of sequence change rate. Especially, it has strong discrimination ability for subtle differences in sequence, and correlation values are accepted more intui- tively. With entropy method, the segments, which has large degree of dispersion, get a small weight as its entropy is bigger.
