报告主题：Optimal Intraproject Learning
Motivated by a project management problem faced by the CBG of Huawei Corporation, we study the problem of intraproject learning, where information gained from certain completed tasks in a project may be used to complete similar later tasks in the same project more efficiently. 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.
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 intractability of the model and 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 more than 20% improvement in project duration. In general, our model and algorithm provide 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 beneficial, thus motivate project managers to understand and apply intraproject learning to improve the performance of their ongoing projects.
