导流方案目标权重的确定及定性目标量化

Rational Definition of Objective Weight Coefficients and Quantification of Qualitative Objectives in Multiobjective Decision of Diversion Schemes

目标权重系数的合理确定，直接影响到导流方案多目标决策结果的准确性，意义重大。采用了带有自调节功能的改进层次分析法（ＩＡＨＰ），该方法自然满足一致性，能使决策者较容易做出比较判断，避免主观臆断性，从而科学、合理地确定目标的权重。定性目标的量化，是个困扰决策者的难题，应用了模糊数学和集值统计原理，对定性目标作出切合实际的量化。

Rational definiteness of objective weight coefficient directly influences the accuracy ofresults of multiobjective decision in the diversion schemes. By employing the Improved AnalyticHierarchy Process(IAHP ) with self-regulating function in this paper,the weight coefficients ofmultiobject in the diversion schemes can be easy reasonably determined avoiding subjective conjecture.This method is naturally satisfied with consistency. Furthermore , by using fuzzy mathematics and thetheory of set Occurrence statistics ,the qualitative objective,i.e, difficulty-easiness of construction ,isquantitated to fit in with reality and a dependable basis for multiobjective decision on diversion schemeis provided.
