模糊数学在室内空气质量评价中的应用

Application of Fuzzy Mathematics on Indoor Air Quality Evaluation

随着生话水平的提高和生活方式的改变,人们在室内生活的时间越来越长,室内空气质量的优劣直接影响到人们的工作和生活。尤其是近年来,出现了大规模的装修热,因此而引起的室内空气污染问题也日益突出。为了能够更客观直接准确的反映出室内空气质量好坏,本文依据国家标准GB／T18880-2002中的标准值,将空气质量分为五个等级。并根据模糊数学的基本原理,选取评价因子,建立室内环境质量模糊综合评价隶属函数,确定了模糊矩阵,把它应用于室内环境质量的综合评价中。

As the improving of living standard and changing of life style , people spend more and more time inside the room, thus the quality of indoor air directly affects people＇s work and life. Especially in recent years, thanks to a fever of decorating appeared in large scale ,the problem of indoor air pollution became more and more serious. In order to reflect the quality of indoor air more objectively and correctly ,this article divides the quality of air into five level according to the standard value in National standard GB/T（ 18880 -2002）, And according to fuzzy mathematics basic principle, pick up the factors about evaluation establish the membership function on the overall evaluation membership function of indoor environmental quality define fuzzy matrix and apply it to comprehensive evaluation of indoor environmental quality.
