摘要
本文研究了灰色评判矩阵的拓扑结构,并且在得到灰色评判矩阵的序结构矩阵的基础上,讨论了灰色评判矩阵白化和求解过程的保序性问题.
The rank preservation to the grey judgement matrix and the evaluating, methods on three levels are discussed. The row vectors of grey matrix{i}∈ Rn+ are the base level; according to the priority rank ofder, the elements{ i} classified into the grey rank equivalence classes are the intermediate level while the permutation groups based on the grey class sets are the high level. In order to obtain the solution that can preserve the judge's priority ranking, the first requirement is that the grey judgement matrix should have rank correlation or asymptotic rank correlation, and the second is that the evaluating method of priority weights should be one for preserving the rank.
