Abstract

The objective of this study was to propose economic order quantity model for perishable items under inspection with constant demand, without lead time, no shortage, and all screened items in each cycle but the inspection error was occurred. In this proposed model, optimal order quantity with the minimum total cost per time unit was obtained. Furthermore, a numerical example was displayed to the support theoretical study and sensitivity analysis of fraction of perishable items affecting expected total cost per unit time. The results share that a fraction of perishable was increased then the expected total cost per time unit would also be increased.
