Weekly Capacity at 99% expected weekly uptime: a worked example

Push expected weekly uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a planner needs to compare weekly demand with realistic production line capacity

The inputs for this scenario

  • Planned daily line output: 5,200 units / day (unchanged)
  • Production days per week: 5 days / week (unchanged)
  • Expected weekly uptime: 99 % (raised for this scenario; the documented default is 89)
  • Expected weekly good yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross weekly capacity = planned daily output × production days) to the inputs above produces each figure below.
  • At this operating point the engine returns 24,968 units / week for good weekly capacity, the number this scenario is built around.
  • At this operating point the engine returns 26,000 units / week for gross weekly capacity.
  • At this operating point the engine returns 260 units / week for weekly units lost to downtime.
  • At this operating point the engine returns 772 units / week for weekly units lost to rejects.

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 11.24% above the baseline at 24,968 units / week.
  • It computes good units per week from planned daily output times production days, derated by weekly uptime and good yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Good weekly capacity: 24,968 units / week (headline result)
  • Gross weekly capacity: 26,000 units / week
  • Weekly units lost to downtime: 260 units / week
  • Weekly units lost to rejects: 772 units / week
