针对横截面数据的灰色关联度分析问题,研究了常用灰色关联度在横截面数据的适用性.提出具有放射变换保序性的灰色距离关联度,实例说明距离关联度的实用性与有效性.将灰色距离关联度推广到系统因素为矩阵的矩阵范数关联度,且在多属性群决策问题的成功应用证明了其合理性.
Aiming at the problem of gray relational analysis of cross-section data, the applicability of common gray relational data to cross-section data is studied, and gray relational relevancy of radiation preserving order preserving property is presented. The practicality and effectiveness of distance associating degree are illustrated by examples. The association degree of gray distance is extended to the matrix norm relation degree whose system factor is matrix, and its rationality is proved by the successful application of multi-attribute group decision making problem.
