基于层次分析法的室内空气质量影响因素研究

Research on factors influencing indoor air quality based on analytic hierarchy process

为解决室内空气质量安全问题,分析了人、物以及环境3个总指标中的8项因素,确定因素的等级划分,采用层次分析法对室内环境质量安全进行评价。综合考虑确定影响室内空气质量安全的人的因素、物的因素、环境的因素为影响室内环境质量安全的主要因素,在此基础上把复杂因素看作一个系统。通过分析影响室内空气因素的特征属性、信息来源,划分出相互联系的有序层次,将决策经验量化,互相比较各因素间重要度,构造判断矩阵,计算得出基本指标的重要度并进行一致性检验。结果表明:二氧化碳、二氧化硫、氮氧化物为权重排序前三的影响因素。

In order to solve our indoor air quality and safety issues,analysis of human and environmental factors such as the three general indicators of the eight factors to determine the factor classification.The environmental quality and safety of indoor environment were evaluated by AHP.Considering the factors that affect the safety of indoor air quality,the factors of the environment and the environmental factors are the main factors that affect the safety of the indoor environment.On this basis,the complex factors are regarded as a system.By analyzing the characteristics of the indoor air factors,the source of information,the order of the interrelated order,the decision-making experience is quantified,the importance of each factor is compared with each other,the judgment matrix is constructed,and the importance of the basic indicators is calculated and consistent sex test.The results showed that carbon dioxide,sulfur dioxide and nitrogen oxides are the first three influencing factors of weighting.
