Port, Crane & Terminal Equipment worked example

Structural Steel Yield at 99% target structural steel yield rate: a worked example

What does the result look like when target structural steel yield rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when structural steel yield in port, crane and terminal equipment needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Conforming steel members produced: 8 count (unchanged)
  • Total steel members fabricated: 250 count (unchanged)
  • Target structural steel yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Structural steel yield rate = structural steel yield count ÷ total structural steel yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for structural steel yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for structural steel yield gap to target.
  • At this operating point the engine returns 8 count for structural steel yield count.
  • At this operating point the engine returns 250 count for total structural steel yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target structural steel yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target structural steel yield rate is genuinely sustained, not just peaked for a shift. It is a simple accept ratio and does not weight defects by severity, rework hours, or member criticality, so a low yield of minor cosmetic rejects looks the same as a low yield of load-path failures.

Results at a glance

  • Structural steel yield rate: 3.2 % (headline result)
