摘要
结合超高层项目平行流水、竖向交叉的施工特点,改进关键链技术缓冲区设置方式,从而优化超高层项目进度管理,缩短工期。首先对资源冲突作出定义,并在资源调节中确定资源约束系数。然后以风险偏好度、信息交互度、奖惩系数三个指标评价超高层各工序,应用熵权-TOPSIS模型得出不确定性系数。基于资源与不确定性约束计算缓冲。最后对实际案例进行蒙特卡洛模拟和对比分析。结果表明,本文方法所得缓冲尺寸较为合理,能够满足项目缩短工期按时完工的需求。
Combining with the construction characteristics of parallel flow and vertical intersection of super highrise project,this paper improves the way of setting buffer zone of key chain technology,so as to optimize the schedule management of super high-rise project to shorten the duration.Firstly,resource conflict is defined and resource constraint coefficient is determined in resource reconciliation.Then three indexes,risk appetite degree,information interaction degree and reward and punishment coefficient,are used to evaluate each process of super high rise,and the uncertainty coefficient is derived by applying entropy weight TOPSIS model.The buffer is calculated based on the resource and uncertainty constraints.Finally,Monte Carlo simulation and comparative analysis are performed for the actual cases.The results show that the buffer size obtained by the method in this paper is more reasonable and can meet the demand of shortening the project duration and completing it on time.
