A deteriorating inventory model with a temporary price discount

Inventory models considering a temporary price discount have recently become an active area of research. In this study, an extension is made to consider the fact that some commodities may deteriorate during storage. The models also incorporate three additional assumptions that have been neglected by researchers. Two models for the exponentially deteriorating items with a temporary price discount are developed for a regular and non-regular inventory replenishment time. Our goal in this research is to maximize the total cost saving during the temporary price discount order cycle. A numerical example is provided to illustrate the theory.
