Robot Batch Capacity at 99% expected cell uptime: a worked example

Push expected cell uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when committing to a batch size on a robot cell so the good parts the batch will actually produce is on one page, not the brochure number.

The inputs for this scenario

  • Parts per robot cycle: 4 parts / cycle (unchanged)
  • Cycles per batch window: 600 cycles (unchanged)
  • Expected cell uptime: 99 % (raised for this scenario; the documented default is 88)
  • Expected first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross batch capacity = parts per robot cycle x cycles per batch window) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,305 good parts / batch for good batch capacity, the number this scenario is built around.
  • At this operating point the engine returns 2,400 good parts / batch for gross batch capacity.
  • At this operating point the engine returns 24 good parts / batch for batch uptime loss.
  • At this operating point the engine returns 71.28 good parts / batch for batch first-pass yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected cell uptime sits at 88% and the headline result is 2,049 good parts / batch, this scenario comes in 12.5% above the baseline at 2,305 good parts / batch.
  • It computes good parts delivered per batch by multiplying parts-per-cycle and available cycles, then derating for 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 batch capacity: 2,305 good parts / batch (headline result)
  • Gross batch capacity: 2,400 good parts / batch
  • Batch uptime loss: 24 good parts / batch
  • Batch first-pass yield loss: 71.28 good parts / batch
