Nozzle Count at 65% nozzle station or crew uptime: a worked example

Suppose nozzle station or crew 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 good nozzle assembly or installation output from nozzles per cycle, available cycles, uptime, and accepted yield.

The inputs for this scenario

  • Nozzles completed per cycle: 12 nozzles / cycle (held at the documented default)
  • Available nozzle build or install cycles: 40 cycles (held at the documented default)
  • Nozzle station or crew uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Accepted nozzle yield: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross nozzle count = nozzles completed per cycle × available nozzle build or install cycles.
  • Good output capacity works out to 306 units at these inputs, and this is the headline figure for the scenario.
  • Gross capacity before uptime and yield works out to 480 units at these inputs.
  • Availability loss works out to 168 units at these inputs.
  • Reject or rework allowance works out to 6.24 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where nozzle station or crew uptime sits at 90% and the headline result is 423 units, this scenario comes in 27.78% below the baseline at 306 units.
  • It multiplies per-cycle nozzle output by available cycles for gross capacity, then derates that by station uptime and accepted yield to give good shippable output. 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 output capacity: 306 units (headline result)
  • Gross capacity before uptime and yield: 480 units
  • Availability loss: 168 units
  • Reject or rework allowance: 6.24 units
