Effective management of perishable inventory systems is often strewn with challenges, especially when a strong trade-off relationship exists between shortage and wastage of perishables: A smaller inventory increases the chance to lose sales (leading to higher expected shortage cost), while a...

We derive the stationary distribution of the regenerative process W(t), t ≥ 0, whose cycles behave like an M / G / 1 workload process terminating at the end of its first busy period or when it reaches or exceeds level 1, and restarting with some fixed workload $$a\in (0,1)$$ . The result is...

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...
