关键链多项目进度计划优化

摘要

CCPM (Critical Chain Project Management) considered people's behavior factors in project scheduling, but project scheduling theory didn't directly relate to people's behavior factors, therefore it was difficult to include them and got effective project network planning. The relationship of people's behavior factors and critical chain project scheduling, people's behavior factors on critical chain multi-project scheduling were analyzed. Then a mathematical optimization model, heuristic scheduling rules were proposed, and activity selection method was designed by adopting reverse topological sort for multi-project network, which based on critical chain multi-project planning to solve this problem. Further the relevant optimization algorithm was presented. Finally a case study was conducted to illustrate the solving processes of approach which revealed that it's effective to overcome the people's bad behavior, balance the resources for multi-project, and reduce the transfer of resources among projects.%关键链项目管理考虑了人的行为因素对项目进度计划的影响,但项目调度理论并不直接与人的行为因素相关,很难获得包融人的行为因素的有效项目网络计划.分析了人的行为因素与关键链项目调度的关系以及对关键链多项目调度的影响,在关键链多项目进度计划的基础上提出优化多项目进度计划的数学模型和启发式优先调度规则,设计了以逆向拓扑排序方式选择调度集的过程,给出了相应的优化算法.通过实例验证了该优化方法能够克服人的不良行为因素对关键链多项目进度计划的影响,具有对多项目资源进行平衡、减少资源在项目间的转移等效果.
