摘要
为解决工程施工进度管控关键链技术应用中存在的缓冲区计算方法粗略,缓冲区监控方法脱离实际施工的问题,通过引入风险控制系数、资源影响系数、工序复杂系数、工序位置系数以及环境系数五个指标,运用层次分析法和CRITIC(Criteria Importance Through Intercriteria Correlation)客观赋权法构建缓冲区优化模型;将缓冲区消耗率和项目工作链完成进度百分比相关联,建立了缓冲区动态监控机制。运用缓冲区优化模型和动态监控机制改进关键链技术,将改进关键链技术应用于泵站工程施工进度管理。结果表明:该方法所得到的缓冲区尺寸较为合理,可以实现缩短计划工期和实现缓冲区动态监控,为水利工程施工进度管控提供借鉴。
To address the issue in the application of critical chain technology in current construction progress control,where the buffer calcu⁃lation method is rough and the buffer management method is disconnected from the actual construction progress.This paper constructed a buf⁃fer zone optimization model by introducing five factors:the risk control coefficient,resource impact coefficient,process complexity coeffi⁃cient,process location coefficient and environment,and by using the Analytic Hierarchy Process and CRITIC(Criteria Importance Through Intercriteria Correlation)objective weighting method;a dynamic monitoring mechanism for the buffer zone is established by relating the buf⁃fer zone consumption rate to the completion progress percentage of the project work chain.The buffer zone optimization model and the dynam⁃ic monitoring mechanism are used to improve critical chain technology,which is applied to the construction progress management of pump station projects.The results show that the size of the buffer zone obtained by this method is relatively reasonable,which can shorten the planned construction period and realize dynamic monitoring of the buffer zone,and provide a reference for the construction progress control of water conservancy projects.
