The history determines the inventory level for the replenishment signal – in the reorder level procedure it’s the reorder point and in Kanban it’s the container quantity.

What is the difference between reorder point and safety stock?
Safety stock provides a buffer of inventory for you to dip into when the above circumstances occur, while reorder point provides a buffer of time for you to restock on merchandise. This means fewer rush fees owed to suppliers, less operational chaos, and a more efficient use of warehouse space.
