Assembly Bay Utilization at 98% target bay utilization: a worked example in construction machinery & attachments

What does the result look like when target bay utilization reaches 98%? The full calculation is worked below with real intermediate numbers. balancing shop floor bay capacity against attachment production demand

The inputs for this scenario

  • Scheduled assembly bay hours: 146 hours (unchanged)
  • Available assembly bay hours: 180 hours (unchanged)
  • Target bay utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Assembly bay utilization = scheduled assembly bay hours ÷ available assembly bay hours × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 81.11 % for assembly bay utilization, the number this scenario is built around.
  • At this operating point the engine returns 16.89 points for assembly bay utilization gap to target.
  • At this operating point the engine returns 146 count for scheduled assembly bay hours.
  • At this operating point the engine returns 180 count for available assembly bay hours.

How this compares with the baseline

  • Against the tool's baseline example, where target bay utilization sits at 85% and the headline result is 81.11 %, this scenario lands almost exactly on the baseline at 81.11 %.
  • A figure at this level is achievable when target bay utilization is genuinely sustained, not just peaked for a shift. Scheduled hours are not the same as productive hours — a bay can be 95% scheduled but still lose time to rework, fit-up errors or waiting on plate.
