Production Ramp Planner at 99% achieved uptime during ramp: a worked example in ppe & infection control products

What does the result look like when achieved uptime during ramp reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when production ramp planner 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

  • New-line output per cycle at target rate: 4 units / cycle (unchanged)
  • Ramp-period cycles available: 480 cycles (unchanged)
  • Achieved uptime during ramp: 99 % (raised for this scenario; the documented default is 90)
  • First-pass yield during ramp: 97 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where achieved uptime during ramp 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 achieved uptime during ramp is genuinely sustained, not just peaked for a shift. It models a single ramp point, not the full learning curve; you should re-run it at each ramp stage as uptime and yield improve week over week.

Results at a glance

  • Good production ramp planner capacity: 1,844 units (headline result)
  • Gross production ramp planner capacity: 1,920 units
  • Production ramp planner downtime loss: 19.2 units
  • Production ramp planner yield loss: 57.02 units

Run it with your numbers

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