Cut-To-Length Throughput at 99% line efficiency: a worked example

Push line efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a cut-to-length operator or planner needs a defensible sheets-per-hour rate before committing a delivery date.

The inputs for this scenario

  • Sheets cut: 1,200 sheets (unchanged)
  • Run time: 8 hr (unchanged)
  • Line efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Cut-to-length rate = sheets cut รท run time) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 sheets/hr for effective cut-to-length rate, the number this scenario is built around.
  • At this operating point the engine returns 150 sheets/hr for raw throughput.
  • At this operating point the engine returns 99 % for line efficiency.
  • At this operating point the engine returns 8 hr for run time.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 135 sheets/hr, this scenario comes in 10% above the baseline at 149 sheets/hr.
  • It computes the effective cut-to-length production rate by dividing sheets cut by run time and multiplying by line efficiency. 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

  • Effective cut-to-length rate: 149 sheets/hr (headline result)
  • Raw throughput: 150 sheets/hr
  • Line efficiency: 99 %
  • Run time: 8 hr
