An inventory system for perishable commodities (PIS) with finite shelf size and finite waiting room for demands is studied; the maximum shelf life and the maximum waiting time of a demand are assumed to be either constant or exponentially distributed, and the arrival rates for items and for...

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...
