He and his coauthors created an&＃160;algorithm that, as it turns out, could save Alibaba more than $2.6 million a year.&＃160;The paper,&＃160;&＃8220;Predicting Human Discretion to Adjust Algorithmic Prescription: A Large-Scale Field Experiment in Warehouse Operations,&＃8221;&＃160;is under revision in&＃160;Management Science. The Olin Award, which includes business school recognition and a $10,000 prize, is&＃160;intended to promote scholarly research that has timely, practical applications for complex management problems. Conventional bin-packing algorithms prescribe which items to pack in which sequence in which box.&＃160;They focus on the best use of a&＃160;box&＃8217;s volume.&＃160;But here&＃8217;s the&＃160;problem: Those algorithms tend to overlook how humans might deviate from&＃160;instructions and create delays.&＃160;Workers&＃160;might&＃160;not organize items as the algorithm prescribes&＃160;if, for instance,&＃160;packing&＃160;a box&＃160;is complex because it includes&＃160;numerous&＃160;items or items with unusual shapes.&＃160; It takes the algorithm and the executors of the algorithm&＃8212;the people delivering the outcomes. &＃160; Dennis Zhang, assistant professor of operations and manufacturing management &＃8220;I call this particular characteristic artificial intelligence and human collaboration," he said. "Such particular characteristics allow us to design better algorithms.&＃8221;&＃160; Here a some takeaways from the research: The new algorithm predicts which orders will confuse workers and adjusts the box size to a larger one.&＃160; The cost of box material may increase, but more savings come from fewer&＃160;packing&＃160;delays.&＃160; AI and robotics can improve human work by providing more support for the decisions people make while working.&＃160; Last year, Zhang and&＃8239;Jake Feldman, assistant professor of operations and manufacturing management, received the award. They used data from Alibaba to test the benefits of&＃8212;and recommend a solution for&＃8212;presenting buyers the optimum variety of products available for purchase with individual online retail stores.&＃160; In this year&＃8217;s winning research, the idea is not to strive for autonomous automation, the authors wrote. &＃8220;We believe that AI and robotics can improve human work by providing more decision support while always empowering human judgment, oversight and discretion.&＃8221;&＃160; Zhang presented his research virtually to members of the Olin community and guests on June 25. Coauthors of the paper are Jiankun&＃160;Sun of Imperial College Business School,&＃160;Haoyuan&＃160;Hu of the Alibaba Group and Jan A. Van&＃160;Mieghem&＃160;of Northwestern University. Olin Award 2020—Dennis Zhang The 2020 Olin Award is presented to Dennis Zhang, assistant professor of operations and manufacturing management, for his paper.
