What is the formula used to calculate Days of Supply (DOS)?

The formula for calculating Days of Supply (DOS) is determined by dividing the Total Fuel On Hand by the Fuel Use Per Day. This calculation provides a clear indication of how many days the available fuel supply will last based on the current consumption rate.

Using this formula allows you to assess the sustainability of fuel resources and effectively plan for resupply or adjustments in fuel consumption. For instance, if you have 1,000 gallons of fuel on hand and your operation uses 100 gallons per day, the calculation would show that you have 10 days of supply remaining.

This understanding is crucial for operational planning and logistics in a tactical environment, where fuel availability can impact mission success and operational readiness.
