摘　　要：考虑链中包含的工序数大小、工序执行时间不确定程度和开工柔性程度三个与具体项目相关的属性,研究关键链项目计划缓冲设置。以项目计划周期和完工保证率为评价目标,通过仿真实验方法评价属性对项目计划的影响。根据仿真实验结果分析,提出缓冲设置的改进方法。算例表明与切粘法和根方差法相比改进方法可显著改善项目计划性能。Three attributes relevant to a specific project, including the number of activities in chain, their uncertain duration and flexible start time , were introduced into critical chain project management for buffer sizing. By means of simulation, the impact of these three attributes on project scheduling in terms of two performance indicators： project duration and on time completion was evaluated. Based on analyzing the simulation experiments, a revised method for buffer sizing was proposed. The case indicates that the performance of project scheduling is significantly improved by using the revised method.
