基于项目团队效能评估的关键链动态缓冲设置研究

Research on dynamic critical chain buffer sizing based on evaluation of project team effectiveness

缓冲对于吸收关键链中的不确定性起到重要作用,而项目团队效能的阶段性特征以及不稳定的动态变化给缓冲设置带来诸多不确定性问题。提出了一种考虑项目团队效能的动态缓冲设置方法,该方法通过评估项目团队动态效能,设定项目团队效能调整系数,对缓冲进行动态设置,使缓冲更具针对性和灵活性。通过算例介绍了该方法的使用过程,并通过MATLAB模拟证实了该方法的有效性和实用性。

Buffer plays an important role to absorb the uncertainty in the critical chain. However, stage characteristics and unstable dynamic changes of the team effectiveness bring various uncertain problems to buffer sizing. A dynamic buffer sizing based on evaluation of project team effectiveness method is proposed to deal with these problems. The method sizes buffer dynamically through evaluating project team effectiveness and setting team effectiveness coefficient, which make the proposed method more realistic and flexible. Finally, a case study is carried out to demonstrate application of the proposed method. And MABTLAB is conducted to validate effectiveness and practicability of the proposed method.
