This inventory is grouped with the ABC Classification method to obtain Category A drug brands, such as: Folamil Genio, Cefxon Injection, Osfit DHA, and Lancit Tablet. After that, the inventory group will be forecasted with the Exponential Smoothing, Moving Average, and Linear Regression methods.

Then the category A drug is controlled by selecting three of the most optimum methods between the Economic Order Quantity (EOQ), the Periodic Order Quantity (POQ), and the Min-Max method.
