Cell Therapy Bioreactor Capacity at 66% expected bioreactor availability: a worked example

This worked example runs the cell therapy bioreactor capacity numbers for a tougher week than the baseline: 66% expected bioreactor availability instead of the typical 92%. Estimate monthly viable culture capacity from available bioreactor runs, planned uptime, and release yield.

The inputs for this scenario

  • Qualified culture volume per bioreactor run: 50 L / run (held at the documented default)
  • Planned bioreactor runs in the period: 18 runs / month (held at the documented default)
  • Expected bioreactor availability: 66 % (the input this scenario stresses; the baseline uses 92)
  • Expected released-run yield: 88 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Scheduled culture capacity = qualified culture volume per run × planned bioreactor runs.
  • Released culture capacity works out to 523 L / month at these inputs, and this is the headline figure for the scenario.
  • Scheduled culture capacity works out to 900 L / month at these inputs.
  • Culture capacity lost to downtime works out to 306 L / month at these inputs.
  • Culture capacity lost to unreleased runs works out to 71.28 L / month at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected bioreactor availability sits at 92% and the headline result is 729 L / month, this scenario comes in 28.26% below the baseline at 523 L / month.
  • Use it during S&OP, campaign sizing, and capital planning to convert scheduled bioreactor time into deliverable, release-eligible culture volume. 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

  • Released culture capacity: 523 L / month (headline result)
  • Scheduled culture capacity: 900 L / month
  • Culture capacity lost to downtime: 306 L / month
  • Culture capacity lost to unreleased runs: 71.28 L / month
