The inventory-routing problem with uncertain travel times

The central problem studied in this work is the Inventory-Routing Problem (IRP), a combined inventory management and routing problem. One of the main assumptions of this model is that the travel times are predictable and fixed. In this work this assumption is dropped and the IRP is studied subject to uncertain travel times. The only available information is that these travel times are independent and symmetric random variables which can take some value from their support interval
