Production Order Release Quantity with net demand to cover of 2,500 units: a worked example

What does the result look like when net demand to cover reaches 2,500 units? The full calculation is worked below with real intermediate numbers. a planner needs to release the right production quantity into the shop

The inputs for this scenario

  • Net demand to cover: 2,500 units (raised for this scenario; the documented default is 980)
  • Expected yield divisor: 0.94 x (unchanged)
  • Lot-size rounding factor: 1.05 x (unchanged)

Working through the calculation

  • Applying the documented formula (Release quantity = net demand to cover ÷ expected yield divisor × lot-size rounding factor) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,793 units for production order release quantity, the number this scenario is built around.
  • At this operating point the engine returns 2,660 units for yield-adjusted demand quantity.
  • At this operating point the engine returns 1.05 x for lot-size rounding factor.
  • At this operating point the engine returns 0.94 x for expected yield divisor.

How this compares with the baseline

  • Against the tool's baseline example, where net demand to cover sits at 980 units and the headline result is 1,095 units, this scenario comes in 155% above the baseline at 2,793 units.
  • A figure at this level is achievable when net demand to cover is genuinely sustained, not just peaked for a shift. It uses a single average yield; if yield varies batch to batch or the process has a fixed minimum loss rather than a percentage, the divisor alone won't capture it.

Results at a glance

  • Production order release quantity: 2,793 units (headline result)
  • Yield-adjusted demand quantity: 2,660 units
  • Lot-size rounding factor: 1.05 x
  • Expected yield divisor: 0.94 x
