Linwei Xin is an Associate Professor in the School of Operations Research and Information Engineering (ORIE) at Cornell University. Prior to Cornell, he was an Associate Professor of Operations Management at the University of Chicago Booth School of Business. He specializes in inventory and supply chain management, where he designs cutting-edge models and algorithms that enable organizations to effectively balance supply and demand in various contexts with uncertainty. 

Xin’s research using asymptotic analysis to study stochastic inventory theory is renowned and has been recognized with several prestigious INFORMS paper competition awards, including First Place in the George E. Nicholson Student Paper Competition in 2015 and the Applied Probability Society Best Publication Award in 2019.

Xin’s recent interest focuses on AI for supply chains, driven by labor shortages, global supply chain disruptions, e-commerce growth, and environmental sustainability. He leverages various tools such as deep learning, LLMs, optimization and probability theory, to address emerging challenges arising from AI-driven automation. His work targets problems in inventory management, robotics and automation in modern warehousing, dual-sourcing, real-time order fulfillment, omnichannel, transportation network design, and solar grazing.

Xin actively collaborates with industry stakeholders to address emerging real-world challenges in online retailing and e-commerce fulfillment, resulting in tangible, real-world impacts. For example, his research on implementing state-of-the-art multi-agent deep reinforcement learning techniques in Alibaba’s inventory replenishment system was selected as a finalist for the INFORMS 2022 Daniel H. Wagner Prize, with over 65% algorithm-adoption rate within Alibaba’s own supermarket brand Tmall Mart. His research on designing dispatching algorithms for robots in JD.com’s intelligent warehouses was recognized as a finalist for the INFORMS 2021 Franz Edelman Award, with estimated annual savings in the hundreds of millions of dollars.

Xin currently serves as an associate editor for Operations Research, Management Science, Manufacturing & Service Operations Management, and Naval Research Logistics.

Xin earned his Ph.D. in Operations Research from the Georgia Institute of Technology in 2015 and a bachelor’s degree in Mathematics from Zhejiang University in 2008.
