摘　　要：为提高关键链项目缓冲监控信号的可靠性,提出一种基于资源冲量的缓冲监控模型。该模型建立输入资源与项目进度的关系式,基于资源冲量计算项目执行实时速率,预估项目执行时间,并根据资源实际供应情况和缓冲消耗量判断项目延误风险。仿真结果表明,缓冲监控模型在面对不同类型的活动时都有良好的监控表现,减少因为错误的预警信号而产生的监控成本,及时地预警可能发生的延误,提高缓冲监控信号的可靠性。To improve the accuracy of buffer monitoring signal,a buffer monitoring model with resource impulse is proposed.The model establishes the relationship between input resources and project schedule,calculates the realtime rate of project execution based on resource impulse,estimates the project execution time,and judges the risk of project delay according to the actual resource supply and buffer consumption.The simulation results show that the buffer monitoring model in this paper can have good monitoring performance in the face of different types of activities,reduce the monitoring cost caused by the wrong warning signal,and timely warn the possible delay,improve the reliability of the buffer monitoring signal.
