The two-bin inventory system is a simple yet effective method where stock is divided into two bins. The first bin is used for regular consumption, while the second serves as a backup. Once the first bin empties, it signals the need to reorder, and replenishment is made before the second bin runs out. This method reduces complexity and ensures uninterrupted supply. It is ideal for small businesses, hospitals, and warehouses with frequently used items. In logistics, the two-bin system supports easy stock monitoring without expensive software or tools. Its simplicity makes it reliable, cost-effective, and suitable for organizations aiming for lean and efficient inventory control.
