摘要
在集对分析法原理的基础上,建立熵权集对分析模型评价空气质量。首先建立了空气质量的评价指标与分级标准,其次利用信息熵原理确定了各项大气污染物指标所占权重,再结合同异反联系度函数确定了空气质量评价等级。应用该模型评价成都市空气质量,并将所得结果与其他方法进行对比,验证了模型的准确性。
A set pair analysis model based on entropy weight is built to evaluate air quality, which is on the principle of set pair analysis method. Firstly we set an evaluation index and a classification standard of air quality, then determined the weight of each air pollution index by means of information entropy principle, and combined the same-indefinite-contrary connection degree function to determine the rating of air quality. The model was used to assess the air quality in Chengdu, and the results were compared with other methods to verify the accuracy of the model.
