Cell Therapy Bioreactor Capacity at 99% expected bioreactor availability: a worked example

Push expected bioreactor availability up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a cell therapy or gene therapy team is checking whether qualified bioreactor slots can cover a monthly batch plan

The inputs for this scenario

  • Qualified culture volume per bioreactor run: 50 L / run (unchanged)
  • Planned bioreactor runs in the period: 18 runs / month (unchanged)
  • Expected bioreactor availability: 99 % (raised for this scenario; the documented default is 92)
  • Expected released-run yield: 88 % (unchanged)

Working through the calculation

  • Applying the documented formula (Scheduled culture capacity = qualified culture volume per run × planned bioreactor runs) to the inputs above produces each figure below.
  • At this operating point the engine returns 784 L / month for released culture capacity, the number this scenario is built around.
  • At this operating point the engine returns 900 L / month for scheduled culture capacity.
  • At this operating point the engine returns 9 L / month for culture capacity lost to downtime.
  • At this operating point the engine returns 107 L / month for culture capacity lost to unreleased runs.

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 7.61% above the baseline at 784 L / month.
  • It computes monthly released culture capacity by multiplying qualified volume per run by planned runs, then derating for bioreactor availability and released-run 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

  • Released culture capacity: 784 L / month (headline result)
  • Scheduled culture capacity: 900 L / month
  • Culture capacity lost to downtime: 9 L / month
  • Culture capacity lost to unreleased runs: 107 L / month
