This article deals with the problem of determining the optimal run time for an economic production quantity (EPQ) model with deteriorating items. The limited display area is assumed to reflect the fact that most manufacturer's outlets have limited shelf space in the proposed model. A mathematical model is formulated to manifest the extended EPQ model for maximizing profits. Theorems 1 and 2 are established to show several intuitively reasonable managerial results. Finally, two numerical examples are given to demonstrate the applicability of the proposed model.
