Lyophilization Capacity at 65% successful cycle yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop successful cycle yield to 65%, then walk the calculation through step by step. Estimate released lyophilized units from shelf loads, containers per load, cycle success, and release yield.

The inputs for this scenario

  • Lyophilizer cycles available: 4 cycles (held at the documented default)
  • Containers per lyophilizer cycle: 480 containers / cycle (held at the documented default)
  • Successful cycle yield: 65 % (the input this scenario stresses; the baseline uses 90)
  • QA released yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross capacity = Lyophilizer cycles available × Containers per lyophilizer cycle.
  • Good output capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross lyophilizer capacity works out to 1,920 units at these inputs.
  • Uptime loss works out to 672 units at these inputs.
  • Yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where successful cycle yield sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to successful cycle yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It applies two flat yield factors and does not model cycle-length variation or cake-quality rejects that depend on formulation, so it is a planning estimate rather than a batch-record figure.
