Abstract
This study aims to formulate an inventory model for deteriorating pharmaceutical items with demand rates following a sine trigonometric function. The methodology includes mathematical modeling, convergence proof, numerical calculations using WolframAlpha and Google Colab, and sensitivity analysis on parameter variations. The optimal values of inventory time and cycle length are 0.9999941 and 0.4288565 respectively, with a minimum average total cost of $2,099,541.610747 per cycle. Sensitivity analysis reveals that parameters such as holding and shortage costs significantly affect total cost, while others show solution stability. This research provides a solid foundation for decision-making in pharmaceutical inventory management.
