摘要

针对目前我国预制装配式建筑评价偏重于 "装配率 "的问题,本文提出了适合我国预制装配式建筑的绿色评价方法,从绿色设计、智能建造、装配式建筑质量和综合效益四个方面确定评价指标体系。此外,采用 DEMATEL 法优化指标权重,再采用 AHP-EWM(层次分析法-熵权法)确定指标体系权重,对评价指标集进行量化分级。最后,本文以陕西省西安市胡坨村公租房项目为例,运用评价方法进行了绿色评估,并对项目各阶段提出了改进建议。

Research on green assessment method of AHP-EWM prefabricated building based on DEMATEL optimization
In view of the problem that the current evaluation of prefabricated buildings in China focuses more on the “assembly rate”, this paper puts forward a green assessment method suitable for prefabricated buildings in China, which determines the evaluation index system according to four aspects: green design, intelligent construction, assembled building quality and comprehensive benefit. In addition, the DEMATEL method is used to optimize the index weight, and then the AHP-EWM (Analytic Hierarchy Process-Entropy weight method) method is used to determine the weight of the index system, and the evaluation index set is quantified and graded. Finally, taking Hutuo village public rental housing project in Xi’an city of Shaanxi Province as an example, this paper uses the evaluation method to conduct a green assessment, and gives suggestions for improvement in each stage of the project.
