| 摘 要： | 基于主观赋权法和客观赋权法对于水质评价有各自的优点和缺点,采用基于遗传算法的组合评价模型,通过该模型将多种评价方法进行组合,并利用遗传算法优化各评价方法的权重,根据评价指标函数值评价出各样本的优劣.通过对评价实例的对比分析,表明该组合评价模型的评价结果更符合实际.

| Abstract: | In view of the merits and defects of the subjective weighting methods and the objective weighting methods in water quality evaluation, the combinational evaluation model based on the genetic algorithm is applied to combine many kinds of evaluation method. The genetic algorithm is used to determine the optimum weight of the model. According to the evaluated values, the excellence and disadvantage of each sample can be presented. Through contrasting and analyzing those values, it is shown that the result of the combinational evaluation method is up to the reality. |
