水源水质模糊评价中的综合赋权和折减系数赋权

Indices combination and coefficient reduction in fuzzy assessment of raw water quality

在水源水质评价中,权值的确定对评价结果的合理性至关重要。在客观定权和主观定权的基础上,提出对二者综合的赋权方法和折减系数赋权法。实例检验表明,二者基本上可以避免单纯使用主观或客观赋权的不足,使评价结果更趋合理。

The assignments of the weight parameters in raw water quality assessment are very important to the rationality of the result. On the basis of the subjective methods and objective methods, an integrated method and a coefficient-reducing method will be offered in this paper. The success of practice shows that these two methods can generally avoid the weak points of the two traditional methods and can make the result of assessment more reasonable.
