基于SEM-FAHP的装配式建筑预制构件供应商选择

Research on Supplier Selection of Precast Element inPrefabricated Buildings Based on SEM-FAHP

合理优选预制构件供应商是保障装配式建筑质量水平的重要前提。首先,运用文献梳理和专家访谈法构建了装配式建筑预制构件供应商评价指标体系,并运用结构方程进行模型拟合及添加因子路径,最终确定了预制构件供应商评价指标模型;其次,运用模糊层次分析法构建了预制构件供应商选择模型;最后,结合实例对预制构件供应商进行了分析。结果表明:该方法具有一定的科学性和合理性,能为装配式建筑预制构件供应商的选择提供有效的指导。

Reasonable selection of precast element suppliers is an important prerequisite to ensure the quality of prefabricated buildings.First,the precast element supplier evaluation index system is constructed by using the carding and expert interview methods,and the structural equation is used to fit the model and add factor paths.Finally,the precast element supplier evaluation index model is finally determined.The analytic hierarchy process builds a precast component supplier selection model.Finally,the precast component supplier is analyzed with examples.The results show that the method is scientific and reasonable,and can provide effective guidance for the selection of suppliers of prefabricated building components.
