基于DEMATEL的装配式建筑成本影响因素研究

Research on Influencing Factors of Prefabricated Building Cost Based on DEMATEL

高成本是现阶段制约装配式建筑快速发展的重要因素。文章通过对装配式建筑整个建造过程的跟踪调查,从设计、生产、运输、管理和社会五个方面归纳装配式建筑成本影响因素,利用DEMATEL方法对这些因素进行定量分析,分析结果表明,应从技术成熟度、预制率、构件拆分情况、构件运输效率、市场发育程度、国家政策和标准等方面降低装配式建筑的成本,提高装配式建筑发展的核心竞争力。

High cost is an important factor that restricts the rapid development of prefabricated buildings at this stage.Through the follow-up investigation of the whole construction process of the prefabricated building,the article summarizes the influencing factors of the prefabricated building cost from five aspects of design,production,transportation,management and society.The DEMATEL method is used to quantitatively analyze these factors.The analysis results show that the cost of prefabricated buildings should be reduced from the aspects of technology maturity,prefabrication rate,component splitting,component transportation efficiency,market development level,national policies and standards,and the core competitiveness of prefabricated buildings will be improved.
