Single-Use Bioprocess Assemblies worked example

Capacity Gap at 65% assembly line uptime: a worked example in single-use bioprocess assemblies

Here is what the math looks like when conditions slip. We hold every other input steady and drop assembly line uptime to 65%, then walk the calculation through step by step. Estimate capacity gap for single-use bioprocess assemblies using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Assemblies produced per weld/build cycle: 4 units / cycle (held at the documented default)
  • Available build cycles in horizon: 480 cycles (held at the documented default)
  • Assembly line uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass integrity yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where assembly line uptime 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 assembly line uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes uptime and first-pass yield are independent and steady; correlated failures (a bad tubing lot driving both scrap and rework downtime) will make real good capacity lower than the model shows.

Results at a glance

  • Good capacity gap capacity: 1,211 units (headline result)
  • Gross capacity gap capacity: 1,920 units
  • Capacity gap downtime loss: 672 units
  • Capacity gap yield loss: 37.44 units
