Raw Material Quarantine Days with raw material units in quarantine of 3,000 pieces: a worked example

Push raw material units in quarantine up to 3,000 pieces and the picture changes. This example computes every intermediate figure at that operating point. Use it when GMP, QA, QC, validation, manufacturing, or operations teams need a quick planning estimate to plan warehouse space, sampling priority, and production risk from unreleased GMP materials.

The inputs for this scenario

  • Raw material units in quarantine: 3,000 pieces (raised for this scenario; the documented default is 1,200)
  • Material release rate: 85 pieces / day (unchanged)
  • Release acceleration factor: 1.1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Base quarantine days = Raw material units in quarantine รท Material release rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 32.09 days for protected days of supply, the number this scenario is built around.
  • At this operating point the engine returns 35.29 days for unprotected days.
  • At this operating point the engine returns 3,000 pieces for material units in quarantine.
  • At this operating point the engine returns 85 pieces / day for daily usage.

How this compares with the baseline

  • Against the tool's baseline example, where raw material units in quarantine sits at 1,200 pieces and the headline result is 12.83 days, this scenario comes in 150% above the baseline at 32.09 days.
  • It converts quarantined raw material units into days of protected supply by dividing units by the release rate, then adjusting for any release-acceleration factor. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Protected days of supply: 32.09 days (headline result)
  • Unprotected days: 35.29 days
  • Material units in quarantine: 3,000 pieces
  • Daily usage: 85 pieces / day
