指出了关键路线法 (CPM)现存在的问题 ,介绍了近年来在国外兴起的项目关键链管理 (CCPM)的基本思想和对 CPM的改进。项目关键链管理的基本思想是根据概率理论和组织行为学理论 ,以 5 0 %的概率估计工期 ,将单个工序的不确定因素统一放在项目缓冲区考虑。将关键链作为项目管理的重点 ,通过项目缓冲区和项目汇入缓冲区的管理来减少延误 Points out the problems existing in the key line method (CPM), and introduces the basic idea of ​​CPM (Project Critical Chain Management) that has arisen abroad in recent years and the improvement of CPM. The basic idea of ​​project key chain management is to estimate the construction period with a probability of 50% according to the theory of probability and the theory of organizational behavior, and to consider the uncertainties of a single operation in the project buffer uniformly. Use key chains as the focus of project management and reduce delays through the management of project buffers and project import buffers
