摘　　要：为提高项目的综合绩效,基于活动的运营成本进行缓冲确定。提出项目活动弹性的概念,用以表示项目活动适合被提取缓冲的大小,进而确定项目缓冲;在缓冲确定的基础上,提出累计缓冲的概念,并结合滚动期的设置,建立有良好缓冲再分配能力的缓冲监控模型。仿真结果显示:基于项目弹性进行缓冲确定可以大大减少预警频次,尤其是红色预警,并可以改变经典缓冲监控方法红色预警随着项目运行不断增加的趋势;相较于静态缓冲监控法和相对缓冲监控法,项目成本和综合绩效都有了极大的改进,因此能够有效地降低项目成本,保证项目的按时完工。In order to improve the comprehensive performance of the project,the project buffer is determined based on the operating cost of activities.We therefore propose a new concept,Project resilience,to indicate and determine the buffer that should be taken from the activity duration.A buffer monitoring model with good buffer redistribution capability is next established based on the setting of rolling periods and the cumulative buffer.The simulation results show that the proposed method can significantly reduce the warning frequency,especially the red warning frequency,and can improve the adverse trend of traditional buffer monitoring methods that red warning frequency increases with the implementation of the project.Compared with the static buffer monitoring method and the relative buffer monitoring method,the project cost and the comprehensive performance of the proposed method are greatly improved.Therefore,it can effectively reduce the cost of the project and ensure the project completed on time.
