关键链项目计划制定中的工期裕量问题研究

Study on Duration Buffer in Critical Chain Project Management

摘要: 合理准确地确定工期裕量的大小是成功实施关键链项目管理的关键。在对作业工期、工期裕量等分析研究的基础上, 剖析了现有两种工期裕量确定方法 C&P 和RSE 的特点, 给出了确定工期裕量的新方法, 最后运用 Monte Carlo 模拟技术, 验证了本文提出的方法的有效性和实用性

Abstract: To reasonably and accuratly estimate the size of duration buffer is the key to successfully carry out the critical chain project management (CCPM). Based on the study of activity duration and duration buffer, a new method to estimate duration buffer is proposed after analyzing the characteristic of C&P (cut and paste method) and RSE ( root square error method). Finally, the validity and function of the newmethod is tested and verified by the Monte Carlo imi2 tated technique
