Optimal ordering policies for deteriorating items with controllable deterioration rate and time dependent quadratic demand

This paper presents a deterministic inventory model for deteriorating items when the deterioration rate is controllable using preservation technology and the demand rate is a quadratic function of time. The optimal cost of the system is calculated allowing shortages. Further it is assumed that the holding cost is a linear function of time. A numerical example is given and the robustness of the model is tested through sensitive analysis.
