【摘要】 在可变模糊集理论基础上,结合二元比较确定指标权重方法,提出地下水质评价可变模糊评价方法,该方法能够合理地确定样本指标对各级指标标准区间的相对隶属度,并且能够通过变化模型及指标权重,确定出样本的评价等级,提高对样本等级评价的可信度。将该方法应用于地下水水质综合评价,评价结果表明,由于考虑了模型参数与权重的可变性,评价结果可信度高。更多还原

【Abstract】 Based on the theory of variable fuzzy set,the variable fuzzy assessment method is established.This method can reasonably identify the relative membership degree between the sample index and standard interval of each level index and determine properly the assessment level of each sample by changing the model and its parameters,so that the reliability of assessment can be improved.The proposed method is applied to groundwater quality evaluation.The evaluation results show that the method and corresponding model are reliable and easy to use.更多还原
