Reuse Loop Turnover at 99% loop availability: a worked example

What does the result look like when loop availability reaches 99%? The full calculation is worked below with real intermediate numbers. a team needs to verify reusable asset availability and loop velocity for a reuse loop

The inputs for this scenario

  • Assets completed per reuse loop cycle: 45 assets / cycle (unchanged)
  • Available reuse loop cycles: 72 cycles (unchanged)
  • Loop availability: 99 % (raised for this scenario; the documented default is 92)
  • Usable return yield: 96 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross reuse loop turnover = assets completed per reuse loop cycle × available reuse loop cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,079 good units for good reuse loop turnover, the number this scenario is built around.
  • At this operating point the engine returns 3,240 good units for gross reuse loop turnover.
  • At this operating point the engine returns 32.4 good units for reuse loop turnover lost to downtime.
  • At this operating point the engine returns 128 good units for reuse loop turnover lost to rejects or rework.

How this compares with the baseline

  • Against the tool's baseline example, where loop availability sits at 92% and the headline result is 2,862 good units, this scenario comes in 7.61% above the baseline at 3,079 good units.
  • A figure at this level is achievable when loop availability is genuinely sustained, not just peaked for a shift. It assumes availability and yield are steady averages over the period; seasonal return spikes, a backlog of assets stuck in the field, or a one-off contamination event will break the steady-state estimate.

Results at a glance

  • Good reuse loop turnover: 3,079 good units (headline result)
  • Gross reuse loop turnover: 3,240 good units
  • Reuse Loop Turnover lost to downtime: 32.4 good units
  • Reuse Loop Turnover lost to rejects or rework: 128 good units
