基于模糊层次分析模型的高校室内空气质量评价与分析

EVALUATION AND ANALYSIS ON THE INDOOR AIR QUALITY OF COLLEGES BASED ON FUZZY ANALYTIC HIERARCHY PROCESS

随着室内空气污染问题越来越受重视,对室内空气进行环境评价以了解室内空气品质成为急需解决的问题。基于层次分析法和模糊综合评判法,提出了模糊层次分析法(FAHP),并应用于高校室内空气品质评价。对某高校室内的甲醛、氨、TVOC、苯、甲苯、二甲苯进行测定,并对测定数据先后采用单一层次分析法和模糊层次分析法进行评价。其中模糊层次分析法是通过对污染物相对重要性比较,建立判断矩阵,经运算和一致性检验得出各污染物权重向量,再确定评价集合,构造各污染物的隶属函数,得到单因素评价矩阵,各污染物的隶属度与其权重的乘积即为评价结果。与单一层次分析法的评价结果对比,模糊层次分析法能够更全面、客观地反映高校室内空气品质的实际状况。

More and more attention has been paid on the indoor air pollution scientific evaluation system of the indoor air environment becomes an urgent problem. Based on analytic hierarchy process and fuzzy comprehensive evaluation method, fuzzy analytic hierarchy process( FAHP) was proposed and applied to the indoor air quality evaluation of colleges. After measuring concentration of formaldehyde,ammonia,TVOC,benzene,toluene,xylene in indoor air,a single analytic hierarchy process model,and then the fuzzy analytic hierarchy process model were used in turn to evaluate these data. FAHP is to establish judgment matrix by the comparison of the relative importance of pollutants,calculate and consistency check each pollutant weights vector,then determine the evaluation set,construct the subordinate function of each pollutant and single factor evaluation matrix. Multiplying the subordinate degree by the weight of each pollutant,the evaluation result can be gained. The evaluation result is compared with that of single analytic hierarchy process, indicating that FAHP can comprehensively and objectively reflect the actual condition of indoor air quality in the colleges.
