讲座标题问题:Optimal Intraproject Learning

晓喻人:赵文辉,上海勾串院安泰经济与营院通饬

略:Motivated by a project management problem faced by the Consumer Business Group of Huawei Corporation, we study the application and optimization of intraproject learning. Under intraproject learning, information gained from completing some tasks in a project is used to complete similar later tasks in the same project more efficiently. This is possible when, for example, the difficulty of the tasks becomes better understood, or the efficiency of the resources used becomes better known. While the project management literature suggests the potential value of using this information within the same project, our work is apparently the first to model and optimize intraproject learning. Since lessons learned consume time, companies may underinvest in intraproject learning. To address this issue, we model the tradeoff between investing time in learning from completed tasks and achieving reduced durations for subsequent tasks, to minimize total project cost. We show that this problem is highly intractable. We develop a heuristic that finds near optimal solutions, and a strong relaxation that allows some learning from partially completed tasks. For the project at Huawei Corporation, our model and algorithm provide a greater than 20% improvement in project duration. More generally, our procedure finds learning solutions that enable reductions in project duration averaging 7% for projects with 40 tasks and 22% for those with 200 tasks. Our sensitivity analysis results identify project characteristics where intraproject learning is most worthwhile. In doing so, they motivate project managers to understand and apply intraproject learning to improve the performance of their ongoing projects.
