摘要
首先通过举例说明“两两对比价值法”存在的问题。“两两对比价值法”没有弄清对抗矩阵Ｒ和ＡＨＰ中判断矩阵间的关系，从而由本方法给出的检验对抗矩阵的一致性及求目标权系数的计算方法均没有科学依据；在能定量表达的目标属性下方案的两两比较法中，“两两对比价值法”给出的“整体比较”人为地改变了给定目标属性下各方案指标值间的比例关系，从而使构造出的对抗矩阵同实际情况相差甚远；“两两对比价值法”的ｒ—ｔ转换是使目标属性的平均相对价值为负值的根本原因。在此分析的基础上，文中给出了一种改进的方法，从而使该方法更加完善、合理。
A few errors in the comparative value methods between each other are pointed out by practical cases: It doesn't understand the relation between confrontation matrix R and judgement matrix in AHP correctly, the methods testing the consistency of confrontation matrix and calculating the weight coefficient of indexes were lack of scientific basis; in the comparative methods between each other under the quantitative indexes, the total comparison artificially changes the proportion relation between the index values of alternatives , which leading to the great difference between confrontation matrix and the practical situation; rt transformation was the essential reason for negative value in average relative value of index. On the basis of the analysis, this paper presents an improved method, it will make the comparative value method more perfect and reasonable.
