The award-winning paper was entitled \u201cAsymptotic Optimality of Tailored Base-surge Policies in Dual-sourcing Inventory Systems,\u0022 co-authored with ISyE assistant professor \u003Cstrong\u003EDavid A. Goldberg\u003C\/strong\u003E. Xin and Goldberg studied dual-sourcing inventory systems, in which one supplier is faster and more costly, while the other is slower and cheaper. Such systems are common in practice, yet notoriously difficult to optimize. Recently, Tailored Base-surge (TBS) policies have been proposed as a heuristic for such models, and shown numerically to perform well as the lead time difference between the two suppliers grows large. This paper provides a theoretical foundation for this phenomenon by proving that a TBS policy is asymptotically optimal as the lead time of the slow supplier grows large.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EXin graduated with his Ph.D. in OR from ISyE (2015), co-advised by Goldberg and Professor \u003Cstrong\u003EAlexander Shapiro\u003C\/strong\u003E; he is now an assistant professor of Industrial and Enterprise Systems Engineering at University of Illinois Urbana-Champaign.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EHao Yan\u003C\/strong\u003E, ISyE Ph.D. student, along with assistant professor \u003Cstrong\u003EKamran Paynabar\u003C\/strong\u003E and Carolyn J.
