Definition

A single‑period inventory decision model for perishable or single‑opportunity products in which a decision maker chooses an order quantity Q before observing random demand; the optimal Q maximizes expected profit (or minimizes expected cost) and is determined by the critical‑fractile relation linking underage and overage costs to the demand distribution.
