摘要: 应用关键链项目管理方法时,由于项目的复杂性,在确定关键链和非关键链后,进一步插入汇入缓冲时,常常会出现资源再次冲突,需要对计划进行重排,重排后又出现关键链断裂、汇入缓冲起不到保护作用等问题。针对这些问题,本文采用分散缓冲法制定项目调度计划,并用项目实例证明了方法的可行性和通用性,且设计仿真实验将分散缓冲计划与重排后的关键链调度计划进行比较,结果发现当项目活动时间的变化性较小时,应用分散缓冲法还可以获得较好的项目绩效。

Abstract: In the application of critical chain buffer management, when the critical chain and non-critical chains are identified, some resource conflictions emerge again because of the complexity of project, which is to be solved by rescheduling. After rescheduling some new problems emerge, gaps may be created in the critical chain and some feeding buffers appear unavailable for protection. This paper aims to set up a project plan by the scattered buffers method to avoid those problems. And project examples are used to prove the feasibility and universality of this method. Furthermore, simulation experiments are designed to compare the scattered buffered plan with rescheduled critical chain plan. The results of the experiments show that scattered buffered plans perform better in the projects with small activity duration variability.

Key words: project management, critical chain, scattered buffer, centralized buffer
