基于关键链技术的项目进度管理研究综述

Review of A Technology Based on Critical Chain for Project Scheduling

关键链技术是在约束理论基础上发展起来的一种新型项目进度管理技术。该技术不仅考虑了工序的执行时间和工序间的紧前关系约束,而且还考虑了工序间的资源冲突,强调了在项目执行过程中的动态管理以及整个项目流程的持续改进。作为一种新的项目进度管理技术,已经引起了众多学者的关注和探索。文章通过对现有文献的梳理,归纳出基于关键链技术的项目进度管理的三个研究方向:关键链如何确定、缓冲区的大小如何确定和关键链技术在项目管理中的应用,并详细介绍了三个方向的研究进展,同时提出基于关键链技术的项目进度管理需要进一步研究的几个方向。

The critical chain is a new technique that applies the Theory of Constraints to project management. It not only takes into account the activity durations and precedence relations, but also considers resource conflicts among project activities. It stresses the importance of the dynamic management in the process of project implementation and the continuous improvement of the whole project procedure. As a new project scheduling technique, it has aroused many scholars＇ concerns and explorations. Based on a critical analysis of the existing literature, this paper sums up three research directions of a technology based on critical chain for project scheduling： how to determine the critical chain, how to determine the size of the buffer and critical chain project management application. Moreover, this paper introduces research process on the three studies in detail. Finally, the paper indicates suggestions for further research.
