摘要
以环境污染指数为基础 ,提出了综合集成方法———模糊关联分析法 (FRA) ,并将其应用于大气环境质量评价之中。该方法融合了模糊综合评判法 (FCE)和灰色关联法 (GR)的优点 ,能够处理模糊性和不确定性信息 ,在亦此亦彼的现象中寻求差异 ,判断出在上一层次中亦此亦彼的信息 ,在下一层次可能是非此即彼。通过实例分析和与其它方法的比较 ,该方法评价结果客观。
Based on environmental pollution index, a synthesized method, fuzzy relation analysis (FRC), is obtained by combining fuzzy comprehensive evaluation and gray relation method,and it is applied to air environmental quality assessment. The method is used to deal with uncertain information, so that finding the difference between illegibility. Through empirical study and comparing FRC with other methods, the result of evaluation is very rational and impersonal.
