This paper explores a deterministic inventory mathematical model for deteriorating items with cubic demand function with respect to time. In the model, shortages are also allowed. Further, it shows that the cubic demand function is convex and gives the optimal solution. A 3-Dimensional graphical representation is used to show the convexity of this model. An illustration is also given to verify the various effects of parameters that are used to calculate the total inventory cost.
