AHP法在水利工程设计方案优选中的应用

AHP method was applied for optimization design of water conservancy engineering

以水利工程中某水库除险加固为例,采用层次分析法(AHP)对工程存在的风险进行分析。根据模型中各层次因素的相对重要性差异,定量表示客观现实情况,通过计算确定每一层次全部因素相对重要性权值,得到了各方案相对最高层目标的重要性次序组合权值,为定性问题的定量解决提供了理论依据和方法。计算结果表明:应用AHP法确定方案二最优。

In the case of danger-removing and strengthening of a reservoir, Analytic Hierarchy Process（AHP） was applied to engineering risk a- nalysis. The relative importance of each level factors in the model, on the basis of objective reality judgment, gave quantitative explain that the relatively important weights of all factors at each level were calculated and determined. The relative importance of the top goal of the program or- der combination weights was got subsequently, and it provided the solution of the theoretical basis and method of the quantitative of the qualitative problem. The results show that scheme 2 is the most advantageous.
