摘要
在拓广了灰色关联度建模的理论基础与打破单纯依据曲线相似性来衡量关联性大小的思想框架的基础上 ,采用数理统计中变异系数的计算方法 ,提出了一种改进的灰色关联度量化模型 ,并将其运用到一个实际算例中 ,结果表明它对已有的关联度模型有较大的改进 ,具有良好的性质。最后 ,得出灰色关联度只是刻划线性关系的量化模型 ,应该谨慎使用的结论。
In general view, there are some limitations in the normal gray interconnect degree model, the main goal of this paper is to put forward a revised gray interconnect degree on the basis of broadening the theory basis for constructing gray interconnect degree model and breaking the ideal frame of only using curve’s shape similar to assess the gray interconnect degree, which uses the method of calculating variance coefficient of statistics, and applies it in a practical example, the result proves that the revised model has significant revision compare to the normal ones and has excellent properties. At the end of this paper, the authors point that the gray interconnect degree model can only score the linear relation of different factors, and must be used cautiously.
