摘　　要：针对项目计划阶段资源约束影响项目进度和项目执行过程中的资源短缺导致工期延误的问题,提出了基于替代资源变异度的增量缓冲设定方法。首先,基于关键链项目各项工序的资源供应风险确定是否使用替代资源;其次,根据资源供应风险和替代资源变异度计算缓冲大小,确定最优工期,改进项目进度网络;最后,通过案例模拟仿真证明了本文所提方法在改善项目进度计划,降低执行过程中的资源风险对项目工期的影响及提高按时完工率等方面的有效性。To avoid the project delay caused by resource constraints at the project planning stage and the resource shortage during the project implementation,an incremental buffer sizing method based on alternative resource variability is proposed. Firstly,based on the resource-supply-risk of each critical chain activity,we determine whether or not to utilize alternative resources. Secondly,according to the resource supply risk and the alternative resource variability,we calculate the buffer size,determine the project duration and optimize the project progress network. Finally,we prove that the proposed method can improve the project schedule effectively,reduce the impact of resource risk on the project duration and improve the on-time completion rate.
