Adhesive Inventory Shelf Life with usable adhesive inventory on hand of 120 cartridges, kg, or ml: a worked example

This worked example runs the adhesive inventory shelf life numbers for a tougher week than the baseline: usable adhesive inventory on hand of 120 cartridges, kg, or ml instead of the typical 240 cartridges, kg, or ml. Estimate protected days of adhesive supply from inventory on hand, daily usage, and shelf-life safety factor.

The inputs for this scenario

  • Usable adhesive inventory on hand: 120 cartridges, kg, or ml (the input this scenario stresses; the baseline uses 240)
  • Average daily adhesive usage: 18 units/day (held at the documented default)
  • Shelf-life safety factor: 1.25 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Unprotected days of supply = usable adhesive inventory รท average daily adhesive usage.
  • Shelf-life protected days works out to 5.33 days at these inputs, and this is the headline figure for the scenario.
  • Unprotected inventory days works out to 6.67 days at these inputs.
  • Usable adhesive inventory works out to 120 units at these inputs.
  • Average daily adhesive usage works out to 18 units/day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where usable adhesive inventory on hand sits at 240 cartridges, kg, or ml and the headline result is 10.67 days, this scenario comes in 50% below the baseline at 5.33 days.
  • Use it when setting reorder points, planning around an adhesive's expiry dates, or deciding whether to hold buffer stock of a long-lead bonding material. 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

  • Shelf-life protected days: 5.33 days (headline result)
  • Unprotected inventory days: 6.67 days
  • Usable adhesive inventory: 120 units
  • Average daily adhesive usage: 18 units/day
