Panel Throughput at 65% line efficiency: a worked example

Suppose line efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Panel Throughput measures how many finished panelboards or switchgear assemblies your line actually turns out per hour, both at raw pace and after accounting for real-world efficiency losses.

The inputs for this scenario

  • Panels completed in the shift: 1,200 units (held at the documented default)
  • Productive assembly runtime: 8 hr (held at the documented default)
  • Line efficiency (uptime and yield): 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw panel throughput = completed output รท runtime.
  • Effective throughput works out to 97.5 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units / hr at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 27.78% below the baseline at 97.5 units / hr.
  • Divides completed output by productive runtime for raw throughput, then multiplies by an efficiency factor to give effective panels per hour. 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

  • Effective throughput: 97.5 units / hr (headline result)
  • Raw throughput: 150 units / hr
  • Efficiency: 65 %
  • Runtime: 8 hr
