基于关键链方法的多项目管理

传统多项目管理中的主要问题表现在级联效应、多任务工作、行为效应等三个方面。本文提出五步骤法将关键链管理中的关键链调度、同步化、缓冲管理应用于多项目管理，建立了关键链多项目管理方法(CCMPM)，并构建了由三个项目组成的多项目环境实例，以工期为评估标准，利用模拟软件Crystal Ball 2000．5模拟项目实施过程，1000次模拟结果显示，经CCMPM优化前后项目平均完工时间为320天／295天，完工保证率为90％的工期为330天／301天。

Mult-project Management Based on Critical Chain Method

ATraditional project management encounters many difficulties like cascade effect, multitasking and behavior effect in a multiple projects environment. Applying critical chain scheduling, pipelining and buffer management, this paper establishes a new method, namely Critical Chain Multi-Project Management (CCMPM). A three-project example is used to test the CCMPM. The simulation using the Crystal Ball 2000.5 shows the CCMPM can reduce the average completion time of 1000 runs from 320 days to 295 days, whilst the completion time with 90% reliability using the CCMPM is 330 days, compared with 301 days by traditional approach.
