Ammunition Demand Forecast Gap Calculator with available primer and case and projectile capacity for the period of 2,100,000 units: a worked example

This scenario runs the ammunition demand forecast gap calculator calculation on the strong side: available primer and case and projectile capacity for the period of 2,100,000 units, with every other input held at its documented default. a planner needs to quantify the gap between available supply and forecast demand

The inputs for this scenario

  • Available primer/case/projectile capacity for the period: 2,100,000 units (raised for this scenario; the documented default is 840,000)
  • Forecast demand for finished rounds or components: 920,000 units (unchanged)
  • Reference (baseline) forecast demand: 920,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Supply surplus or shortfall = available component supply or capacity - forecast demand) to the inputs above produces each figure below.
  • At this operating point the engine returns 128 % demand gap for demand forecast gap, the number this scenario is built around.
  • At this operating point the engine returns 1,180,000 units for supply surplus or shortfall.
  • At this operating point the engine returns 2,100,000 units for available component supply or capacity.
  • At this operating point the engine returns 920,000 units for forecast demand.

How this compares with the baseline

  • Against the tool's baseline example, where available primer and case and projectile capacity for the period sits at 840,000 units and the headline result is -8.7 % demand gap, this scenario comes in 1,575% above the baseline at 128 % demand gap.
  • Use it during monthly or quarterly S&OP reviews, before committing powder and primer allocations, or when validating whether current capacity can cover a new government or commercial contract. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Demand forecast gap: 128 % demand gap (headline result)
