摘　　要：从实际操作角度出发,本文构建了一种基于变权函数的水质综合评价多属性决策模型。首先,对水质评价中需要考虑的指标关注程度差异、指标表现程度差异及相关的妥协机制均进行了意义明确的参数化描述。其次,在机理上保证了指标权重随样本表现上的差异能进行有控制的再分配,同时,在结果上保证了较高的关注指标的表现对综合评价值始终具有相对较高的影响力,而且在样本表现相近的情形下又保持较高的区分度。最后,结合水质综合评价算例进行了分析与讨论。The paper develops a comprehensive evaluation multi-attribute decision-making model of water quality on the basis of the variable weight function from the perspective of practical operation. Firstly, a univocal parametric description for the differences among the degree of concern and the performance level as well as compromise mech- anism related to indicators is given. Secondly it ensures that the index weight with different performances of the sample can carry out a controlled redistribution in mechanism, which guarantees that performance indicators that are in a high degree of concern always have a relatively large influence on the evaluation. Moreover, it can highly differentiate in the case of samples with the similar performance. Finally, some numerical examples of water quality evaluation are analyzed and discussed.
