  1. AHP 一、AHP介绍 1、T.L.Satty70年代中期提出 2、是一种整理和综合主观判断的客观方法 3、适用于多目标、多准则的复杂评价问题。 二、AHP的步骤 1、明确问题 2、建立层次结构模型 3、建立判断矩阵及其一致性检验 4、层次单排序 5、层次总排序

  3. 1-9标度法:

  4. 判断矩阵:

  5. 和积法(层次单排序):

  6. 一致性检验:

  7. 1 1/4 2 4 1 8 1/2 1/8 1 CI为判断矩阵B的一致性指标,与B的最大特征根λmax有关: CI=(λmax-n)/(n-1) C1-P中, BW=(0.5455,2.1824,0.2728) × 0.1818 0.7272 0.0910 (BW)1=1×0.1818+1/4×0.7272+2×0.0910=0.5455 (BW)2=4×0.1818+1×0.7272+8×0.0910=2.1824 (BW)3=1/2×0.1818+1/8×0.7272+1×0.0910=0.2728 λmax=1/3(0.5455/0.1818+2.1824/0/7272+0.2728/0.0910)=3 CI=(3-3)/(3-1)=0,因此CR=0/0.58=0<0.1,C1-P具有满意的一致

  8. 层次总排序:
