Technical Note—Asymptotically Optimal Control of Omnichannel Service Systems with Pick-up Guarantees

Both walk-in and online customers appear in many service systems such as restaurants. Online customers are often given a target time for pick up, and the quality of the food/beverage can degrade if it is ready before the arrival of online customers. This distinctive feature brings essential difficulties in the analysis and control of such systems. In “Technical Note: Asymptotically Optimal Control of Omnichannel Service Systems with Pick-up Guarantees,” Gao, Huang, and Zhang study the optimal control problem of such service systems based on a two-class single server queueing model. The paper proposes a nearly-optimal policy that keeps the server idle when the queue of online customers drops below a threshold and there are no walk-in customers.
