基于改进AHP定权的优序法在地下水水质评价中的应用

基于三标度提出的改进层次分析法(AHP)降低了传统方法构造判断矩阵的主观性,通过特定的数学变换将判断矩阵转化为一致最优阵避免了繁琐的逻辑一致性检验过程,给出确定权重系数的一种简单计算方法。最后通过实例验证,基于改进AHP定权的优序法计算简单、方便,在地下水水质评价中能够合理地给出各水体样本的污染程度和类别。

Application of weighted priority order method based on improved AHP to groundwater quality assessment

Improved Analytic hierarchy process based on three-mark method weaken the subjectivity in the course of constructing and judging matrix through traditional methods,a complex consistency test process was avoided by the mathematical transformation which judgment matrix is translated into consistency matrix,the paper gave a simple calculation method of weight coefficient.Finally,through the practical examples,it prove that the weighted priority order method can reasonably show the degree and category of the pollution of various water bodies.
