Nonwoven Materials & Technical Textiles worked example

Inventory Coverage with roll stock on hand at the slitter of 3,000 units / day: a worked example in nonwoven materials & technical textiles

Push roll stock on hand at the slitter up to 3,000 units / day and the picture changes. This example computes every intermediate figure at that operating point. Use it when inventory coverage in nonwoven materials and technical textiles is being sized for a buffer or safety stock review.

The inputs for this scenario

  • Roll stock on hand at the slitter: 3,000 units / day (raised for this scenario; the documented default is 1,200)
  • Replenishment lead time for fiber/polymer: 85 days (unchanged)
  • Safety-stock multiplier: 1.1 units (unchanged)

Working through the calculation

  • Applying the documented formula (Inventory coverage cycle stock = inventory coverage daily usage × inventory coverage 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 roll stock on hand at the slitter sits at 1,200 units / day and the headline result is 12.83 days, this scenario comes in 150% above the baseline at 32.09 days.
  • It converts on-hand inventory and daily usage into protected days of supply and compares that against the replenishment lead time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close 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
