Daily Capacity at 99% expected daily uptime: a worked example

Push expected daily uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a production planner needs a daily output commitment for a conveyorized line or assembly cell

The inputs for this scenario

  • Units completed per line cycle: 1 units / cycle (unchanged)
  • Available line cycles per day: 3,000 cycles / day (unchanged)
  • Expected daily uptime: 99 % (raised for this scenario; the documented default is 87)
  • Expected good yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross daily capacity = units per cycle × available cycles per day) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,881 units / day for good daily capacity, the number this scenario is built around.
  • At this operating point the engine returns 3,000 units / day for gross daily capacity.
  • At this operating point the engine returns 30 units / day for daily units lost to downtime.
  • At this operating point the engine returns 89.1 units / day for daily units lost to rejects.

How this compares with the baseline

  • Against the tool's baseline example, where expected daily uptime sits at 87% and the headline result is 2,532 units / day, this scenario comes in 13.79% above the baseline at 2,881 units / day.
  • It computes good units per day from units per cycle times available cycles per day, derated by daily 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 daily capacity: 2,881 units / day (headline result)
  • Gross daily capacity: 3,000 units / day
  • Daily units lost to downtime: 30 units / day
  • Daily units lost to rejects: 89.1 units / day
