为了解决施工进度计划不具备柔性、实施过程中需根据实际进度不断调整变化等问题,在关键链项目管理中引入柔性技术,在其缓冲区设置时考虑实际进度控制中多种不确定性因素,从而提高了柔性关键链缓冲区设置的有效性.首先,基于柔性关键链技术,识别影响施工进度计划的内外部不确定性因素,并对这些不确定性因素进行评估和量化,在根方差法的基础上进行改进,提出了柔性关键链缓冲设置的新方法;然后,采用Monte Carlo模拟法对实例的计算结果的有效性进行验证,并计算出实例项目的完工率以及缓冲消耗情况;最后将新方法结果与C&PM,RSEM方法得到的结果进行对比分析.研究结果表明,这种基于多种不确定性因素的设...

In order to solve the problem that the construction schedule is not flexible, and that the implementation process should be adjusted according to the actual progress, flexi- ble technology is introduced in the critical chain project management, and many uncertain- ties in the actual progress control are taken into account when the buffer is set, which can improve the effectiveness of flexible critical chain buffer settings. Based on the flexible criti- cal chain technology, the internal and external uncertain factors influencing the construction schedule are identified,evaluated and quantified...
