层次分析法改进及其在橡胶林种植对流域输沙影响评价中的应用
Improvement of AHP and Its Application to Impact Assessment of Rubber Plantation on Sediment Transport in Watershed
摘要
Abstract
The analytic hierarchy process(AHP) is widely used in the calculation of index weight and decision;but there are limitations in the construction of the judgment matrix and the consistency test.For the two key issues as numerical scale and consistency test in traditional AHP and its improved methods,an unlimited scale method is proposed to fully consistent with the original intention of experts in determining the relative importance among the factors,and constructed entirely consistency matrix by way of passing,to adjust the maximum difference in original matrix when it does not content with the consistency.The assessment index weight application examples of watershed sediment transport impact of rubber plantation in Yunnan Province show that the modified method not only reduces the difficulty of experts to determine the value of the matrix,but also resolve the issue that matrix does not content with the consistency while retaining the maximum information on the original matrix.关键词
