Raw Material Quarantine Days with raw material units in quarantine of 600 pieces: a worked example

This worked example runs the raw material quarantine days numbers for a tougher week than the baseline: raw material units in quarantine of 600 pieces instead of the typical 1,200 pieces. Estimate raw material quarantine duration from inventory awaiting release, daily material release rate, and any acceleration factor.

The inputs for this scenario

  • Raw material units in quarantine: 600 pieces (the input this scenario stresses; the baseline uses 1,200)
  • Material release rate: 85 pieces / day (held at the documented default)
  • Release acceleration factor: 1.1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base quarantine days = Raw material units in quarantine รท Material release rate.
  • Protected days of supply works out to 6.42 days at these inputs, and this is the headline figure for the scenario.
  • Unprotected days works out to 7.06 days at these inputs.
  • Material units in quarantine works out to 600 pieces at these inputs.
  • Daily usage works out to 85 pieces / day at these inputs.

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 50% below the baseline at 6.42 days.
  • Use it when sizing raw material safety stock, evaluating QC release throughput, or justifying an accelerated or risk-based release program. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Protected days of supply: 6.42 days (headline result)
  • Unprotected days: 7.06 days
  • Material units in quarantine: 600 pieces
  • Daily usage: 85 pieces / day
