Distributionally Robust Inventory Control When Demand Is a Martingale

Demand forecasting plays an important role in many inventory control problems. To mitigate the potential harms of model misspecification in this context, various forms of distributionally robust op…

JD.com pioneered same-day delivery as a standard service in China’s business-to-consumer e-commerce sector in 2010. To balance the urgent need to meet growing demands while maintaining high-quali…

On a Deterministic Approximation of Inventory Systems with Sequential Service…

ervice-level constraint is often used as a metric to directly control the quality of service (e.g., managing the probability of stockout) in practice. Many inventory problems with service-level con…

Technical Note—Understanding the Performance of Capped Base-Stock Policies …

Single-sourcing lost-sales inventory systems with lead times are notoriously difficult to optimize. In this paper, we propose a new family of capped base-stock policies and provide a new perspectiv…
