模糊综合评判密闭环境空气质量的方法研究

Air quality assessments by Fuzzy Multifactorial Evaluation in closed environment

由于密闭环境中各组分对人身心健康的影响具有一定的随机性和模糊性,所以很难用一个严格准确的方法对密闭环境内的空气质量进行评判,文中将模糊综合评判的原理和方法应用到对密闭环境空气质量评价中,并利用层次分析法确定了权重系数,较好地解决了如何确定加权系数这一难题。最后根据对密闭环境空气质量等级划分,用上述方法对一实例空气质量进行了评价,评价结果能比较客观地反映真实情况,从而为改善密闭环境空气质量提供了一种科学方法。

The air quality in a closed environmental is hard to be assessed with a strict and standard method because the air influence in a closed environmental on personal health is stochastic and uncertain. Fuzzy Multifactorial Evaluation was applied to evaluate the air quality in a closed environment, and the weight number was ascertained by using Analytical Hierarchy Process, which is difficulty to be solved. By this new method, the air quality in a closed environment can be evaluated according to their grades. The assessment is reliable and effective. It provides a scientific method for improving the quality of the closed environmental air.
