Repair Turnaround Time at 75% queue, test, and paperwork allowance: a worked example

What does the result look like when queue, test, and paperwork allowance reaches 75%? The full calculation is worked below with real intermediate numbers. a depot repair or service operations lead needs to estimate turnaround time for a repair queue

The inputs for this scenario

  • Repair orders in queue: 72 orders (unchanged)
  • Repair completion pace: 0.28 orders/min (unchanged)
  • Queue, test, and paperwork allowance: 75 % (raised for this scenario; the documented default is 65)

Working through the calculation

  • Applying the documented formula (Base repair processing time = repair orders รท repair completion pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 450 turnaround hr for repair turnaround time, the number this scenario is built around.
  • At this operating point the engine returns 257 turnaround hr for base repair processing time.
  • At this operating point the engine returns 75 % for queue, test, and paperwork allowance.
  • At this operating point the engine returns 0.28 orders/min for repair completion pace.

How this compares with the baseline

  • Against the tool's baseline example, where queue, test, and paperwork allowance sits at 65% and the headline result is 424 turnaround hr, this scenario comes in 6.06% above the baseline at 450 turnaround hr.
  • A figure at this level is achievable when queue, test, and paperwork allowance is genuinely sustained, not just peaked for a shift. It models a single steady completion pace; if repair complexity varies widely or technicians are pulled to field calls, actual turnaround will swing around this estimate.

Results at a glance

  • Repair turnaround time: 450 turnaround hr (headline result)
  • Base repair processing time: 257 turnaround hr
  • Queue, test, and paperwork allowance: 75 %
  • Repair completion pace: 0.28 orders/min
