保序性和目标权重计算方法

RANK PRESERVATION AND EVALUATION METHODS OF WEIGHTS

围绕保序性要求，介绍了证券矩阵序结构的评价和先检验矩阵序结构相关程序，后计算目标相对权重（优先权）的求解步骤，并且对几种计算目标权重的方法作了一些分析、比较。

This paper is written for the rank preservation of evaluating of priority weights and the rank structure of positive reciprocal or approximately positive reciprocal matrices that are inconsistent. We show that the satisfying rank structrue of a matrix is the important condition to preserve rank of solutions. Therefore, in the first step we had better test the rank correlation of the rank structure matrix, and the second we evaluate the priority weights. The rank correla-tion of matrix A can be checked easily.
