基于熵权-TOPSIS法地下空间装修环境质量模糊评价

Fuzzy Evaluation of Environmental Quality for Underground Space Decoration Based on Entropy Weight-TOPSIS Method

针对地下空间装修过程环境质量评价存在的不确定性问题,利用熵权优化的优劣解距离模型和模糊综合评价法定量分析了某地下工程装修过程的湿度、温度、风速、甲醛和粉尘对环境质量的影响.研究表明,各影响因素权重不同,对比计算结果,可用定量指标直观判别环境质量和影响环境质量的主要因素;贴近程度S可以直接判别各种环境的质量优劣,贴近程度S越接近1,环境质量越好.风速为S主要影响因素,风速较低的样本环境S值为0.85,提高风速的样本环境S_(max)值为0.89,环境质量随风速的增大而提高.将该方法应用于地下工程装修过程环境质量的评价,其结果可为地下工程的管理和相关政策的制定提供依据.

In response to the uncertainty issue in environmental quality evaluation during the decoration process of underground spaces,a distance model based on entropy weight optimization was used to quantitatively analyze the impact of humidity,temperature,wind speed,formaldehyde,and dust on environmental quality during the decoration process of an underground project using fuzzy comprehensive evaluation method.The results show that the weights of each influencing factor are different,and compared with the calculation results,quantitative indicators can be used to visually identify the environmental quality and the main factors affecting environmental quality.The degree of proximity S can directly determine the quality of various environments,the closer the degree Sis to 1,the better the environmental quality,and the calculation Sprovides a basis for adjusting and judging the environmental quality;The S_(max)value of the sample with low wind speed was 0.85,and the ambient S_(max)value of the sample with increased wind speed was 0.89,and the environmental quality increased with the increase of wind speed.The method is applied to the evaluation of environmental quality in the decoration process of underground engineering,and the results can provide a basis for the management of underground engineering and the formulation of related policies.
