4.7 – Adjust the inventory calculations by using the DOH factor. Once the Forecasted Daily Usage is established, the control variable to adjust inventory quantities is the “DOH” in the formula, the replenishment time. Change this variable in the Material Flow chain for that part and the quantities will automatically be recalculated. Caution: quantities will be recalculated for all items with that Material Flow Chain. To change one part only you’ll need to define a new chain.
