1 引言在水利工程设计、施工和运行管理中,存在着大量的评价及决策问题,由于多种因素相互关联、相互制约及难以定量等特点,限制了数量方法的运用,也增大了对这类问题进行正确评价及决策的难度。自从T.L.Saaty在70年代提出AHP(层次分析法)以来,无疑给解决水利工程系统中的各种评价及决策提供了新的途径和方法。AHP方法是综合定性与定量分析,对多目标多准则的系统进行分析评价的一种方法。它将人的主观判断为主的定性分析,以一定的标度进行量化,用数值来显
1 Introduction In water conservancy project design, construction and operation management, there are a large number of evaluation and decision-making problems, due to many factors interrelated, mutual restraint and difficult to quantify and other characteristics, limiting the use of quantitative methods, but also increased the Class problems for the correct evaluation and decision-making difficulty. Since T.L.Saaty proposed AHP (Analytical Hierarchy Process) in the 1970s, it has undoubtedly provided a new way and method to solve various evaluation and decision-making in hydraulic engineering system. AHP method is a comprehensive qualitative and quantitative analysis of multi-objective multi-criteria system analysis and evaluation of a method. It will be the main person of subjective judgments of qualitative analysis, to a certain degree of quantification, the value of significant
