摘要项目进度管理对项目的成功与否起着关键的作用。但由于一般项目进度管理方法在管理上的刚性、片面性和低效性，从而越来越难适应现代项目进度管理的要求。因此，本文选择可能弥补一般项目进度管理方法缺陷的关键链技术进行讨论，具有重要的理论与实践意义。在本文中，从关键链的识别、缓冲区大小的设置、缓冲区管理机制的设置等方面入手，构建了基于关键链技术的项目进度管理模型。关键链技术压缩安全时间，设置缓冲区对安全时间进行“聚合”管理与控制，有效地消除了帕金森法则、学生综合症等人为因素的影响。关键词：项目进度 关键链 缓冲区Abstract The project schedule management plays a key role in the success of a project. However, due to the general project schedule management approaches rigidness, sidedness and inefficiency .they are increasingly difficult to meat the progress of modern project management requirements. Therefore, the research on the critical chain technology which may compensate for the defects in the general project schedule management has important theoretical and practical significance. In this thesis, the paper builds a project schedule management model based on the critical chain technology from three aspects, including identifying the critical chains, setting the buffer size, and setting the buffer management mechanism. The critical chain technology compresses the safety time, and sets the buffers to aggregate the safety time. So it effectively eliminates the affects of the man-made factors, such as Parkinson's Law, Murphy's Law and Students' Syndrome and effectively compensates for the deficiencies of the general project schedule management approaches.Key Words：the project schedule the critical chain the buffer 目录0 引言50.1 问题的提出与背景..............................................50.2 国内外讨论现状................................................60.2.1 关键链的识别............................................
