基于灰色区间层次法的装配式建筑施工可持续水平综合评价

Comprehensive Evaluation of Sustainable Level of Prefabricated Building Construction Based on Grey Interval Analytic Hierarchy Process

基于对装配式建筑可持续发展要求,选择装配式建筑不确定因素最多的施工阶段作为研究对象,从社会影响、环境保护、资源利用、经济目标、施工技术、施工管理6个维度选取24个细化指标建立装配建筑施工可持续水平综合评价指标体系。将区间层次分析法和灰色聚类法结合,构建基于灰色区间层次分析法的装配式建筑施工可持续水平综合评价模型。利用该评价模型对西北某装配式建筑施工可持续水平进行综合评价。结果表明,该装配式建筑施工可持续水平为较好可持续,综合评价结果与该项目实际施工情况基本吻合,验证了该评价模型的可行性和适用性。

Based on the requirements for the sustainable development of prefabricated buildings,the construction stage with the most uncertain factors of prefabricated buildings is selected as the research object.From the six dimensions of social impact,environmental protection,resource utilization,economic objectives,construction technology and construction management,24 detailed indexes are selected to establish a comprehensive evaluation index system for the sustainable level of prefabricated buildings.With the combination of interval analytic hierarchy process and grey clustering method,a comprehensive evaluation model of sustainable level of prefabricated building construction is constructed based on interval analytic hierarchy process-grey weighted clustering method.The evaluation model is used to comprehensively evaluate the construction sustainability level of a prefabricated building in Northwest China.the results show that the construction sustainability level of the assembly project is good sustainable,and the comprehensive evaluation results are basically consistent with the actual construction situation of the project.The feasibility and applicability of the evaluation model are verified.
