考虑资源切换的多项目关键链进度计划制定与表示

Multi-project Critical Chain Scheduling and Graphic Denotation Considering the Switch of the Resource

多个项目的项目进度计划制定过程中,项目之间存在着资源的冲突,瓶颈资源相比在项目内工作间的切换,在项目间的切换通常需要更多的时间,如何科学合理地制定资源调度计划,使得多项目整体的最终完工时间最短,是多项目项目管理面临的一个重要问题。本文在传统单项目关键链计划技术的基础上,将瓶颈资源在并行项目间的切换时间赋予资源缓冲区并使之串联起并行项目,进而在不同切换方案中选取最优。与此同时,对传统的项目进度计划图进行了改进,提出了时间轴关键链项目进度计划图的概念,使得关键链项目计划与控制有了更加便捷直观的体现。

The conflicts of resources among projects exist in the process of multi-project scheduling. Compared with switching among the works in one projects, the switching of the bottleneck resources require much more time typically. So how to make reasonable resource scheduling plan in order to guarantee the final completion time of the projects to be the shortest is a significant problem of multi-project management. Based on the traditional scheduling technology of critical chain of single project, this paper will add the switching time of bottleneck resources among parallel projects in resource buffers as bridges to connect the projects and then choose the best one of different switching schemes. At the same time, the article also improves the traditional project schedule planning graphs. Time Axis critical chain project schedule plan is presented to make it more convenient and intuitive of critical chain project scheduling and control
