Sterilization & Sterile Barrier Manufacturing worked example

Cleanroom Utilization at 98% target cleanroom utilization: a worked example in sterilization & sterile barrier manufacturing

Push target cleanroom utilization up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use it to judge whether the cleanroom in Sterilization & Sterile Barrier Manufacturing is a bottleneck or has spare capacity.

The inputs for this scenario

  • Cleanroom production hours logged: 320 hr (unchanged)
  • Cleanroom scheduled available hours: 400 hr (unchanged)
  • Target cleanroom utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Utilization = hours in use รท hours available) to the inputs above produces each figure below.
  • At this operating point the engine returns 80 % for utilization, the number this scenario is built around.
  • At this operating point the engine returns 18 points for gap to target.
  • At this operating point the engine returns 320 value for used amount.
  • At this operating point the engine returns 400 value for available amount.

How this compares with the baseline

  • Against the tool's baseline example, where target cleanroom utilization sits at 85% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • It computes cleanroom utilization as production hours divided by available hours, then reports how many percentage points you are below your target. 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

  • Utilization: 80 % (headline result)
  • Gap to target: 18 points
  • Used amount: 320 value
  • Available amount: 400 value

Run it with your numbers

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