基于变权集对分析的室内空气品质的评价研究

摘要

The indoor air quality was evaluated by measuring the indoor pollutant concentration.Three basic factorsof indoor air quality, such as concentration, evaluation grade and weight coefficient, were analyzed by seven basic factors in this paper.By establishing set pair analysis model, the degree of similarity and difference between the evaluation object and the evaluation standard was described by the connection degree.Based on the existing basic weights, the variable weight formula was introduced to make the concentration of pollutants change synchronously with the evaluation grade.This method was used to evaluate the indoor air quality of four buildings in a district, the result was more scientific and reasonable.The evaluation method was more comprehensive and intuitive for indoor air quality.%对室内中的污染物浓度进行测量,科学评价室内空气品质.分析了室内空气质量七种污染物的浓度、评价等级、权重系数三个基本要素.通过建立集对分析模型,用联系度来描述评价对象与评价标准的同异程度,评价结果清晰地显示了集合之间的关系结构.在已有基本权重的基础上,引入变权公式,使污染物的浓度随评价等级同步动态变化.并用该方法对某小区的四栋楼的室内空气质量进行综合评价,该分析结果更加科学合理.该评价方法对室内空气质量评价更加全面、直观.
