摘要
In this paper, an economic order quantity model for deteriorating items with time discounting has been developed for varying demand pattern over a fixed planning horizon. Optimal solutions with complete backlogging and without backlogging are established and has proven that the total variable cost is convex. The main contribution of this paper is based on the assumption of the demand which is the linear function of the instantaneous stock level I(t). In this paper, a new type of demand has been considered which will help us to obtain qualitative insights without much analytical complexity. Optimal solutions of the proposed models are derived and effects of deterioration on the inventory replenishment policies are studied with the help of numerical examples.
