Textiles & Apparel Manufacturing worked example

Roll Usage Calculator at 98% cutting and application efficiency: a worked example

Push cutting and application efficiency up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use it when roll usage in textiles and apparel manufacturing needs a buy quantity for the next textiles and apparel manufacturing run and you do not want to short the line.

The inputs for this scenario

  • Units of product to cut or coat: 500 units (unchanged)
  • Roll material consumed per unit: 0.08 units / unit (unchanged)
  • Cutting and application efficiency: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Theoretical roll usage amount = roll usage area or quantity × roll usage use per unit) to the inputs above produces each figure below.
  • At this operating point the engine returns 40.82 units for required roll usage quantity, the number this scenario is built around.
  • At this operating point the engine returns 40 units for theoretical roll usage amount.
  • At this operating point the engine returns 0.82 units for roll usage loss allowance.
  • At this operating point the engine returns 98 % for application efficiency.

How this compares with the baseline

  • Against the tool's baseline example, where cutting and application efficiency sits at 85% and the headline result is 47.06 units, this scenario comes in 13.27% below the baseline at 40.82 units.
  • It computes the required roll quantity by multiplying units by consumption per unit and dividing by an application efficiency factor. 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

  • Required roll usage quantity: 40.82 units (headline result)
  • Theoretical roll usage amount: 40 units
  • Roll usage loss allowance: 0.82 units
  • Application efficiency: 98 %
