摘要
在可变模糊集理论的基础上，结合有序二元比较法确定指标权重，提出了退役铀矿山辐射环境质量可变模糊评价法。该方法能够合理的确定样本指标对各级指标标准区间的相对隶属度，通过变化模型参数，确定出样本的评价等级，提高对样本等级评价的可信度。运用该方法对退役铀矿山辐射环境质量进行评价，评价结果表明该方法的可行性及可信度高。
Abstract
Based on the theory of variable fuzzy, combined with the binary comparison method to determine the weight of index, author proposed evaluation of radiation environment variable fuzzy assessment approach in uranium mill tailings. 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 evaluation of radiation environment in uranium mill tailings. The evaluation results show that the method is feasible and high reliability.
