End Effector Test Capacity at 65% test cell uptime: a worked example

This worked example runs the end effector test capacity numbers for a tougher week than the baseline: 65% test cell uptime instead of the typical 90%. Estimate end effector test capacity for surgical robotics manufacturing using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • End effectors tested per cycle: 4 units / cycle (held at the documented default)
  • Available test cycles in the window: 480 cycles (held at the documented default)
  • Test cell uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • End effector first-pass yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where test cell 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.
  • Use it for capacity planning, committing test throughput to a production schedule, or targeting the biggest loss between uptime and yield. 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

  • Good end effector test capacity: 1,211 units (headline result)
  • Gross end effector test capacity: 1,920 units
  • End effector test capacity downtime loss: 672 units
  • End effector test capacity yield loss: 37.44 units
