Specialty Films, Membranes & Barrier Materials worked example

Capacity Gap at 99% expected line uptime: a worked example in specialty films, membranes & barrier materials

What does the result look like when expected line uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when capacity gap in specialty films, membranes and barrier materials is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Good film output per coating cycle: 4 units / cycle (unchanged)
  • Available coating cycles: 480 cycles (unchanged)
  • Expected line uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass yield: 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 expected line uptime 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 expected line uptime is genuinely sustained, not just peaked for a shift. It assumes uptime and yield are independent multipliers and uses steady-state averages, so it will not reflect a specific bad shift or the interaction between a slow line and rising scrap.

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
