摘要
对已有的端点型三角白化权函数进行改进,构建了一类中心点型三角白化权函数,进而对两类白化权函数的灰类交叉特性、聚类系数和端点选取等方面进行比较研究,结果表明中心点型白化权函数优于端点型白化权函数最后以高校学科建设综合实力评估为例对两类方法进行对比分析,说明了新方法的有效性.
In this paper, a new grey evaluation method based on reformative triangular whitenization weight function is researched. The end-point triangular whitenization weight function proposed is revised. And a new enter-point triangular whitenization weight function is constructed. Then several aspects, such as the cross- ing properties of grey cluster, clustering coefficient and rules for choosing end-point, of the two whitenization weight functions are compared. The results indicated that the center-point triangular whitenization weight function precede end-point triangular whitenization weight function roundly. Finally, an example about evaluation subject construct of universities is proposed for further analyzing the two methods. It is indicated that the new method is effective.
