TWO-GRADE FUZZY SYNTHETIC EVALUATION METHOD OF INDOOR AIR QUALITY
Evaluation analysis of indoor air quality (IAQ) is generally concerned about certain aspects and cant reveal the problems of the whole conditions entirely. Based on relevant IAQ standards and theories of two-grade fuzzy synthetic evaluation, the method and process to evaluate IAQ have been comprehensively discussed through four aspects, which were physical, chemical, radiant and biological properties. The evaluation process is carded out as follows: Firstly, fuzzy synthetic evaluation model is founded, representative evaluation object set and evaluation object factor set are chosen. Secondly, evaluation levels of IAQ are determined, and then membership grades are calculated, the factor weight is distributed according to the knowledge and experience of the experts. Finally, two grade fuzzy synthetic evaluation of IAQ is obtained. An example of its application is provided, and the result shows that this method is of high precision and offers a new approach to supply more objective evaluation of IAQ.
