讲座题目：Optimal Intraproject Learning

报告人：赵文辉，上海交通大学安泰经济与管理学院教授

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