Layup Cell Capacity at 99% layup cell uptime: a worked example

Push layup cell uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. checking whether a layup cell can support production demand

The inputs for this scenario

  • Parts completed per layup cycle: 3 parts / cycle (unchanged)
  • Planned layup cell cycles in the period: 30 cycles (unchanged)
  • Layup cell uptime (availability): 99 % (raised for this scenario; the documented default is 88)
  • Layup first-pass yield: 94 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross layup cell capacity = parts completed per layup cycle × planned layup cell cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 83.75 parts for good layup cell capacity, the number this scenario is built around.
  • At this operating point the engine returns 90 parts for gross layup cell capacity.
  • At this operating point the engine returns 0.9 parts for layup cell capacity lost to downtime.
  • At this operating point the engine returns 5.35 parts for layup cell capacity lost to scrap or rework.

How this compares with the baseline

  • Against the tool's baseline example, where layup cell uptime sits at 88% and the headline result is 74.45 parts, this scenario comes in 12.5% above the baseline at 83.75 parts.
  • It computes good (sellable) layup-cell output by multiplying parts per cycle and planned cycles, then derating that gross figure by cell uptime and first-pass 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 layup cell capacity: 83.75 parts (headline result)
  • gross layup cell capacity: 90 parts
  • layup cell capacity lost to downtime: 0.9 parts
  • layup cell capacity lost to scrap or rework: 5.35 parts
