Sterilization & Sterile Barrier Manufacturing worked example
Sterilization Cycle Capacity at 65% sterilizer availability: a worked example
Suppose sterilizer availability falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate sterilization cycle capacity for sterilization and sterile barrier manufacturing using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
The inputs for this scenario
- Product units loaded per sterilization cycle: 4 units / cycle (held at the documented default)
- Sterilizer cycles available in the period: 480 cycles (held at the documented default)
- Sterilizer availability (uptime): 65 % (the input this scenario stresses; the baseline uses 90)
- Load-release first-pass yield: 97 % (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Gross sterilization cycle capacity = sterilization cycle capacity output per cycle × available sterilization cycle capacity cycles.
- Good sterilization cycle capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
- Gross sterilization cycle capacity works out to 1,920 units at these inputs.
- Sterilization cycle capacity downtime loss works out to 672 units at these inputs.
- Sterilization cycle capacity yield loss works out to 37.44 units at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where sterilizer availability sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
- It computes good (releasable) sterile units by multiplying units-per-cycle and available cycles into gross capacity, then derating for sterilizer uptime and load-release first-pass yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
