Scan-to-Production Lead-Time Buffer with average daily case demand of 3,000 cases / day: a worked example

This scenario runs the scan-to-production lead-time buffer calculation on the strong side: average daily case demand of 3,000 cases / day, with every other input held at its documented default. Use it when scan-to-production lead-time buffer in dental, orthodontic and prosthetics manufacturing is being sized for a buffer or safety stock review.

The inputs for this scenario

  • Average daily case demand: 3,000 cases / day (raised for this scenario; the documented default is 1,200)
  • Scan-to-production lead time: 85 days (unchanged)
  • Digital workflow buffer: 1.1 cases (unchanged)

Working through the calculation

  • Applying the documented formula (Lead-time case demand = average daily case demand × scan-to-production lead time) 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 inventory.
  • 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 average daily case demand sits at 1,200 cases / day and the headline result is 12.83 days, this scenario comes in 150% above the baseline at 32.09 days.
  • Use it when setting WIP targets for a digital lab, onboarding a new high-volume clinic account, or diagnosing why finishing cells keep stalling between scan intake and production. 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

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