摘要
为科学有效地管理和控制装配式钢结构住宅的成本,从成本发生的源头入手,识别并筛选出25个影响因素,构建了基于解释结构模型的装配式钢结构住宅成本影响指标体系,清晰直观地分析各因素之间的相互影响关系.同时,引入理想点法计算各因素的组合权重,以此得出了主要的影响因素.研究结果显示,钢构件及"三板"构件采购的经济性等6个影响因素对装配式钢结构住宅成本的影响较大,故被确定为成本管理的关键要素.为实现对成本的有效管控,根据分析结果,从控制钢构件及"三板"构件的成本等4个方面提出了改进建议.
Abstract
To scientifically and effectively manage and control the cost of prefabricated steel frame residential buildings,an approach was initiated by addressing the source of cost generation,identifying,and subsequently screening 25 influencing factors.This led to the construction of an impact indicator system for prefabricated steel frame residential building costs based on the Interpretive Structural Modeling(ISM)methodology.The system elucidates the interrelationships among these factors in a clear and intuitive manner.Concurrently,the Ideal Point Method was employed to compute the combined weights of each factor,thereby revealing the principal influencing factors.The research findings indicate that six factors,including the economic feasibility of steel component procurement and that of"Three-board"(referring to prefabricated wall,floor,and roof panels)element acquisition,exert substantial influence on the cost of prefabricated steel frame housing,hence being designated as critical elements for cost management.In order to effectuate effective cost control,according to analysis result,improvement recommendations were put forth in four domains,chief among them being the containment of expenses associated with steel components and"Three-board"elements,derived from the analytical outcomes.
