MODEL INVENTORI BARANG FARMASI YANG DETERIORATING PADA TINGKAT PERMINTAAN MENGGUNAKAN FUNGSI TRIGONOMETRI COSINUS YANG MEMPERTIMBANGKAN TINGKAT PENYIMPANAN
In this study, a deteriorating inventory model of pharmaceutical goods with a demand level using a cosine function that considers the storage level is developed. The mathematical model formulation in this research is assisted by WolframAlpha software while the numerical calculation uses the help of Google Colab software. The results showed that the sensitivity analysis carried out affected the final value, resulting in an up and down trend depending on the parameter whose value was changed. The optimal values generated in this study for seasonal demand patterns and cycle length are 2.000000800 and 0.99999629 with an average minimum total cost of $299.50941951 per cycle. This research can support pharmaceutical inventory management in making the right decision. Keywords : Inventory Model, Deteriorating, Demand Level, Pharmaceutical Goods, Sensitivity Analysis.
