The single-period inventory model applies to inventory situations where demand is uncertain. true…

➤ How do you calculate the optimal order quantity in the single-period (newsvendor) model?
Calculate the optimal order quantity using the critical fractile rule. Compute underage cost Cu and overage cost Co, then find the fractile Cu/(Co+Cu). The optimal Q is the inverse cumulative distribution at that fractile: Q* = F^{-1}(Cu/(Co+Cu)). Use the demand distribution (normal, Poisson, empirical) accordingly.
