摘要
为了有效地控制建筑工程造价,提出基于工程概预算曲线约束的建筑工程造价影响分析方法。依据工程项目成本管控过程中造价的影响因素确定数据来源,构建概预算曲线约束目标模型,并以此得到造价的影响因素,根据建筑工程造价影响参量,基于累积方差贡献度,通过建筑项目成本约束参量自身贡献度进行自适应加权,提取建筑项目成本控制的时间序列特征,得到建筑项目质量、效率与成本优化之间的关联性,从而实现工程造价的管控。通过搭建实验平台对所提方法进行验证,结果显示,利用工程概预算曲线约束分析造价影响因素,能够有效控制建筑工程造价,表现出良好的运行效果。
In order to control the construction cost effectively,this paper puts forward the construction cost control method based on the curve.According to the cost influencing factors in the process of project cost control,the data source is determined,the budget curve constraint target model is constructed,and the cost influencing factors are obtained.According to the construction cost influencing parameters,based on the cumulative variance contribution degree,the self contribution degree of the construction project cost constraint parameters is adaptively weighted to extract the time series characteristics of the construction project cost control.In order to achieve the project cost control,the relationship between the quality,efficiency and cost optimization of the construction project is obtained.The experimental platform is built to verify the proposed method.The results show that the cost influencing factors can be effectively controlled by using the engineering budget curve constraints,which shows a good operation effect.
