Weekly Capacity at 64% expected weekly uptime: a worked example

Suppose expected weekly uptime falls to 64%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate good units per week from daily output assumptions, production days, uptime, and yield.

The inputs for this scenario

  • Planned daily line output: 5,200 units / day (held at the documented default)
  • Production days per week: 5 days / week (held at the documented default)
  • Expected weekly uptime: 64 % (the input this scenario stresses; the baseline uses 89)
  • Expected weekly good yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross weekly capacity = planned daily output × production days.
  • Good weekly capacity works out to 16,141 units / week at these inputs, and this is the headline figure for the scenario.
  • Gross weekly capacity works out to 26,000 units / week at these inputs.
  • Weekly units lost to downtime works out to 9,360 units / week at these inputs.
  • Weekly units lost to rejects works out to 499 units / week at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected weekly uptime sits at 89% and the headline result is 22,446 units / week, this scenario comes in 28.09% below the baseline at 16,141 units / week.
  • It computes good units per week from planned daily output times production days, derated by weekly uptime and good yield. 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 weekly capacity: 16,141 units / week (headline result)
  • Gross weekly capacity: 26,000 units / week
  • Weekly units lost to downtime: 9,360 units / week
  • Weekly units lost to rejects: 499 units / week
