Educational & Classroom Lab Equipment worked example

Classroom Lab Inventory Coverage with available educational equipment inventory of 600 units: a worked example

This worked example runs the classroom lab inventory coverage numbers for a tougher week than the baseline: available educational equipment inventory of 600 units instead of the typical 1,200 units. Estimate days of inventory coverage for finished educational lab equipment, student kits, instruments, furniture components, consumables, or installation hardware.

The inputs for this scenario

  • Available educational equipment inventory: 600 units (the input this scenario stresses; the baseline uses 1,200)
  • Average daily school-order demand: 85 units / day (held at the documented default)
  • Planning reserve divisor: 1.1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw inventory days of coverage = available educational equipment inventory รท average daily school-order demand.
  • 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.
  • Inventory 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 available educational equipment inventory sits at 1,200 units and the headline result is 12.83 days, this scenario comes in 50% below the baseline at 6.42 days.
  • Use it during reorder reviews and seasonal demand planning to decide whether current stock spans the lead time ahead. 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)
