Sterilization & Sterile Barrier Manufacturing worked example

Changeover Time at 7.2% setup, cleaning, and delay allowance: a worked example in sterilization & sterile barrier manufacturing

This worked example runs the changeover time numbers for a tougher week than the baseline: 7.2% setup, cleaning, and delay allowance instead of the typical 10%. Estimate changeover time for sterilization and sterile barrier manufacturing using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Units to process this changeover run: 120 units (held at the documented default)
  • Sealer processing rate: 12 units / min (held at the documented default)
  • Setup, cleaning, and delay allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base changeover time = changeover time workload รท changeover time completion rate.
  • Required changeover time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base changeover time works out to 10 hr at these inputs.
  • Changeover time allowance applied works out to 7.2 % at these inputs.
  • Changeover time completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, cleaning, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it when scheduling format changeovers, sizing buffers before a change, or setting takt-realistic completion times for a run. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required changeover time: 10.72 hr (headline result)
  • Base changeover time: 10 hr
  • Changeover time allowance applied: 7.2 %
  • Changeover time completion rate: 12 pieces / min
