Trailers, Truck Bodies & Specialty Vehicles worked example

Compliance Inspection Time at 12% documentation and setup allowance: a worked example

Push documentation and setup allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when compliance inspection time in trailers, truck bodies and specialty vehicles is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • DOT/FMVSS checkpoints to inspect: 120 units (unchanged)
  • Checkpoints cleared per hour: 12 units / hr (unchanged)
  • Documentation and setup allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base compliance inspection time time = required work รท processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where documentation and setup allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes base inspection time from checkpoint count divided by throughput, then inflates it by a documentation and setup allowance. 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

  • Adjusted run time: 11.2 hr (headline result)
  • Base run time: 10 hr
  • Allowance applied: 12 %
  • Process rate: 12 pieces / min
