Perishable Inventory or Perishable Service Model. Quantities of a perishable resource arrive to a system in discrete time periods to satisfy demands. The resource is only available for a single time period, but unsatisfied demands are backlogged. For instance the resource might be food, blood or human organs that perish after a certain time period, or cargo space on an airline that disappears when the airline departs.
