Repairable stocking and expediting
What is it about?
Repairable spare parts are a major inventory investment aimed to keep equipment such as aircraft, MRI scanners and manufacturing plants up and running. The performance of the inventory system depends on the number of repairables and policies in the repair shop. This paper explains how to optimize these two decisions for different demand scenarios.
Why is it important?
The interaction between stocking and repair is modeled in a tractable manner and insights about optimal policy are obtained. This paper also gives insight into the structure of optimal dual sourcing policies under a base-stock level constraint. Finally is shows that smart use of expediting is an effective buffer next to inventory to deal with uncertain and fluctuating demand.
