Trailers, Truck Bodies & Specialty Vehicles worked example

Weight Estimate with severity of weight overrun of 15 score: a worked example

What does the result look like when severity of weight overrun reaches 15 score? The full calculation is worked below with real intermediate numbers. Use it when weight estimate in trailers, truck bodies and specialty vehicles needs a defensible ranking against other trailers, truck bodies and specialty vehicles risks for the next review.

The inputs for this scenario

  • Severity of weight overrun: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood of weight overrun: 4 score (unchanged)
  • Detectability before shipment: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Weight Estimate risk score = severity × 0.40 + occurrence × 0.35 + detection × 0.25) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 lb for risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for severity.
  • At this operating point the engine returns 4 score for occurrence.
  • At this operating point the engine returns 3 score for detection.

How this compares with the baseline

  • Against the tool's baseline example, where severity of weight overrun sits at 6 score and the headline result is 4.55 lb, this scenario comes in 79.12% above the baseline at 8.15 lb.
  • A figure at this level is achievable when severity of weight overrun is genuinely sustained, not just peaked for a shift. This is a relative prioritization score, not an actual weight in pounds; a high score flags where to investigate but does not tell you how many pounds over target a unit will be.
