【摘要】 随着经济全球化导致市场竞争的日趋激烈,项目管理的内容也越来越复杂,对于项目管理的要求也越来越高。现代项目管理要求周期更短、准时完工率更高、成本更低。传统的项目方法已经无法完全满足现代项目管理的实际需求。基于约束理论的关键链项目管理方法作为一种全新的项目管理方法已经在多个欧美企业获得成功,并也逐步引起了国内许多企业的重视。与传统的项目管理方法相比,关键链项目管理方法在许多方面有显著的优点,能有效地管理项目中的不确定性,缩短项目周期,提高项目效率。由于充分考虑了人的行为因素,关键链项目管理方法较之传统方法更具实用性。关键链的识别是关键链项目管理方法的重要部分,然而现有的关键链识别方法多并没有考虑到项目活动工期的随机性,为此本文提出了一种基于统计学理论的关键链识别方法。试验证明,该方法行之有效,能够在很好的控制项目工期的同时兼顾计划的实用性。缓冲管理是约束理论应对不确定性的有效途径,关键链项目管理方法同样采用设置缓冲区的方法来应对项目的不确定性因素。现有的缓冲大小确定方法未能完全考虑到项目中各个活动自身的特性,为此本文提出了一种自适应的缓冲设置方法,并通过试验证明,该方法能够有效地缩短项目中的汇入缓冲大小,并能有效避免因为缓冲设置产生的新的资源冲突。更多还原

【Abstract】 Because of fierce market competition due to the development of economic globalization,current method of project management become more and more complex, and the requirement for project management also become more and more severe.The project management require shorter project duration, higher just-in-time completion rate,and less cost.Conventional method for project planning and scheduling cannot meet the practical needs of modern project management.The Critical Chain Project Management(CCPM) based on Theory of Constrained(TOC) has been recognized and researched in North America and Europe,and more and more researchers and enterprisers are focusing on the field in China.CCPM is advanced in many aspects. It can manage the uncertainty in the project more efficiently, shorter project duration, and higher management efficiency.Considered the human behavior CCPM are more practical in project execution.The most important part of CCPM is to identify the Critical Chain. Conventional methods for identifying critical chain ignore the randomicity of duration of project activities.In this thesis a method to identifying the critical chain based on statistics is proposed. It is proved that this method is effectively used, and it can not only control the project duration but also be practical.Buffer management is a valuable method to management for uncertainty in TOC, it’s also adopted in CCPM. But conventional method of buffer management ignore the character of each tasks.In this thesis an adaptive method for buffer management is proposed. Test also has been made to prove that this method can shorter the size of feeding buffer and escape the resource conflict because of feeding buffer.更多还原
