An optimal policy for deteriorating items with time-proportional deterioration rate and constant and time-dependent linear demand rate

In this paper, an economic order quantity (EOQ) inventory model for a deteriorating item is developed with the following characteristics: The optimal cycle time and the optimal order quantity have been derived by minimizing the total average cost. A simple solution procedure is provided to illustrate the proposed model. The article concludes with a numerical example and sensitivity analysis of various parameters as illustrations of the theoretical results.
