层次分析模型在室内空气质量评价中的应用研究

当前评价方法没有考虑室内空气质量界线的模糊性,不能真实反映室内空气品质,导致评价结果不准确.提出基于层次分析模型的室内空气质量评价方法,建立室内空气质量评价目标层、准则层和措施层三层递阶的层次结构模型,构造判断矩阵,计算特征向量,得到各自的层次总排序结果,结合室内空气质量评价各指标权重,计算空气各污染物的隶属函数,求导室内空气质量最终评价值.实验结果表明,所提方法获得的室内空气质量评价值与实际调查监测值一致,能够真实反映室内空气质量状况,具有较高的可靠性.

Application of Analytic Hierarchy Process in Indoor Air Quality Evaluation

The current evaluation method does not consider the fuzziness of indoor air quality boundary,and can not truly re-flect the indoor air quality, resulting in inaccurate evaluation results. The indoor air quality evaluation method based on AHP model was proposed to the establishment of indoor air quality target layer,criterion layer and measures three layers of hierarchical structure model of evaluation,construct judgment matrix,calculate feature vector,get the results of their level of total order,ac-cording to the air quality in the room to evaluate the weight of each index,calculate the membership function of each pollutant the air,indoor air quality of the final evaluation value of derivative. The experimental results show that the indoor air quality evalua-tion value obtained by the proposed method is consistent with the actual monitoring value, which can truly reflect the indoor air quality and has high reliability.
