Shelf Life Remaining with daily shipment or depletion rate of 3,000 units / day: a worked example

This scenario runs the shelf life remaining calculation on the strong side: daily shipment or depletion rate of 3,000 units / day, with every other input held at its documented default. Use it when deciding whether ingredients, WIP, finished goods, or customer orders have enough shelf life left to ship, consume, or hold.

The inputs for this scenario

  • Daily shipment or depletion rate: 3,000 units / day (raised for this scenario; the documented default is 1,200)
  • Usable shelf life left at receipt: 18 days (unchanged)
  • Date-code safety stock buffer: 2,500 units (unchanged)

Working through the calculation

  • Applying the documented formula (Shelf Life Remaining cycle stock = daily shipment or usage rate × remaining usable shelf life) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.07 days for protected days of supply, the number this scenario is built around.
  • At this operating point the engine returns 167 days for unprotected days.
  • At this operating point the engine returns 3,000 pieces for inventory.
  • At this operating point the engine returns 18 pieces / day for daily usage.

How this compares with the baseline

  • Against the tool's baseline example, where daily shipment or depletion rate sits at 1,200 units / day and the headline result is 0.03 days, this scenario comes in 150% above the baseline at 0.07 days.
  • Use it when receiving a perishable lot, planning rotation, or deciding whether short-dated stock can clear before it breaches a customer's minimum-life requirement. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
