We present models for inventory systems with perishable commodities (PISs) in which the items are not scrapped after reaching their maximum lifetime but are transferred to a second PIS where they are used to satisfy another random stream of demands. We determine the steady-state distribution of...

We consider a certain class of perishable inventory systems with items and demands arriving at random times. The shelf lifetime of every item is finite and deterministic. Every demand is for a single item and is satisfied by the oldest item on the shelf, if available. Generalizing previous work,...
