摘　　要：在传统的灰关联理论分析基础上,从两个方面进行改进:一是省略了数据预处理,使计算过程简化;另一是在计算关联系数ξi,j时对分辨系数ρ的取值做了合理的判定,同时采用模糊数学中的广义权距离来计算关联度ri,j,使评定精度提高,从而得到了新改进的灰关联分析法,并对该方法计算步骤进行分析。最后采用该方法对四栋大楼的室内空气品质进行评定分析。实践证明,该方法具有简单、可靠、准确等优点,有很强的实用性,为更客观地评价室内空气品质提供了一种新的方法和思路。The research of applying the fuzzy grey relational to analysis the factors affecting indoor air quality was introduced in this paper. The old grey relational analysis was improved from two aspects. The one aspect, disposing data was omitted in order to simplify problem. The other aspect, identification coefficient reasonably was estimated with improving relational coefficient. At the same time, adopted the method of generalized weighted distance in fuzzy theory, the new grey relational degree was calculated in order to advancing evaluating precision. Thus a new improved approach to the grey relational degree was gained. Then calculating processes of the method was analyzed and exhibited. Finally, as was know, being made fuzzy and grey, the indoor air quality of four building could be evaluated and analyzed by this method, on the condition to get a favorable effect. The evaluation result indicated that 1〉3〉2〉4. The practice had testified that the new improved method enjoyed a series of advantages, such as being scientific, original, simple, reliable, adaptable and accurate etc, so the method should be greatly popularized. Therefore, a new approach and idea were being to introduce to get more objective evaluation of indoor air quality.
