First, the distributor's product mix was collected, along with its sales history and current inventory. This information could be processed and analyzed for the next steps.

2.3 Inventory Management: Defining the Replenishment Model
Above all, when analyzing the products and their demand, the use of safety stock and replenishment point was defined . As well as, a replacement model, to meet the needs of lack of product in ready stock. And lack of knowledge of when to place a new order for a certain product;
