Capacity Gap at 99% line uptime after changeovers & jams: a worked example in ppe & infection control products

What does the result look like when line uptime after changeovers & jams reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when capacity gap in ppe and infection control products is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Mask/respirator units per production cycle: 4 units / cycle (unchanged)
  • Available machine cycles in the shift: 480 cycles (unchanged)
  • Line uptime after changeovers & jams: 99 % (raised for this scenario; the documented default is 90)
  • First-pass yield after seal & filtration checks: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross capacity gap capacity = capacity gap output per cycle × available capacity gap cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good capacity gap capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross capacity gap capacity.
  • At this operating point the engine returns 19.2 units for capacity gap downtime loss.
  • At this operating point the engine returns 57.02 units for capacity gap yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where line uptime after changeovers & jams sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when line uptime after changeovers & jams is genuinely sustained, not just peaked for a shift. It assumes a steady cycle rate and fixed uptime/yield; real ramp periods, material stockouts and batch quality swings can push actual output below the model.

Results at a glance

  • Good capacity gap capacity: 1,844 units (headline result)
  • Gross capacity gap capacity: 1,920 units
  • Capacity gap downtime loss: 19.2 units
  • Capacity gap yield loss: 57.02 units
