Sterilization & Sterile Barrier Manufacturing worked example

Production Ramp Readiness at 99% expected line uptime during ramp: a worked example in sterilization & sterile barrier manufacturing

Push expected line uptime during ramp up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when production ramp readiness in sterilization and sterile barrier manufacturing is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Sterile barrier units per seal cycle: 4 units / cycle (unchanged)
  • Available seal cycles in the period: 480 cycles (unchanged)
  • Expected line uptime during ramp: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass yield during ramp: 97 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where expected line 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.
  • It computes good, shippable capacity from output per cycle and available cycles, discounted by expected uptime and first-pass yield. 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

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