Crew Size Calculator at 65% expected uptime: a worked example

Suppose expected uptime 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 crew size for workforce, labor standards and skills planning using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Parts produced per cycle by the crew: 4 units / cycle (held at the documented default)
  • Available production cycles in the window: 480 cycles (held at the documented default)
  • Expected uptime (availability): 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where expected 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.
  • It computes gross crew capacity from output per cycle and available cycles, then multiplies by uptime and first-pass yield to give good (sellable) capacity. 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.

Results at a glance

  • Good crew size capacity: 1,211 units (headline result)
