Decoiler Utilization at 98% target utilization: a worked example

This scenario runs the decoiler utilization calculation on the strong side: 98% target utilization, with every other input held at its documented default. Use it when a slitting or cut-to-length supervisor checks how hard the decoiler is loaded against its target.

The inputs for this scenario

  • Decoiler hours run: 360 hr (unchanged)
  • Decoiler hours available: 480 hr (unchanged)
  • Target utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Decoiler utilization = decoiler hours run รท decoiler hours available) to the inputs above produces each figure below.
  • At this operating point the engine returns 75 % for decoiler utilization, the number this scenario is built around.
  • At this operating point the engine returns 23 points for utilization gap.
  • At this operating point the engine returns 360 value for decoiler hours run.
  • At this operating point the engine returns 480 value for decoiler hours available.

How this compares with the baseline

  • Against the tool's baseline example, where target utilization sits at 85% and the headline result is 75 %, this scenario lands almost exactly on the baseline at 75 %.
  • Use it shift-by-shift or weekly to benchmark a single decoiler or compare two coil lines feeding the same downstream process. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Decoiler utilization: 75 % (headline result)
  • Utilization gap: 23 points
  • Decoiler hours run: 360 value
  • Decoiler hours available: 480 value

Run it with your numbers

  • Every input above is editable in the live Decoiler Utilization calculator, which recalculates instantly and can be shared with the inputs intact.
