Inventory Model having Polynomial Time Cubic Function Demand with Weibull Distribution as Deterioration Rate

This study examines an inventory model for products or objects that deteriorate over time with a cubic demand and a Weibull degradation rate. The model allows for shortages. Additionally, it demonstrates how the cubic demand function is convex and produces the optimal outcome. The convexity of this model is depicted graphically in three dimensions. In order to confirm the model, an illustration is made. The findings of a sensitivity analysis of the optimal solution with regard to the key variables were provided.
