Unloading Time at 17% dock and delay allowance: a worked example
What does the result look like when dock and delay allowance reaches 17%? The full calculation is worked below with real intermediate numbers. Use it to plan inbound appointments, set detention expectations, and size receiving labor before a truck arrives.
The inputs for this scenario
- Pallets to unload from the trailer: 26 pallets (unchanged)
- Forklift unloading rate: 1.8 pallets / min (unchanged)
- Dock and delay allowance: 17 % (raised for this scenario; the documented default is 15)
Working through the calculation
- Applying the documented formula (Base unloading time = pallets to unload รท unloading rate) to the inputs above produces each figure below.
- At this operating point the engine returns 16.9 min for required unloading time, the number this scenario is built around.
- At this operating point the engine returns 14.44 min for base unloading time.
- At this operating point the engine returns 17 % for dock and delay allowance.
- At this operating point the engine returns 1.8 pallets / min for unloading rate.
How this compares with the baseline
- Against the tool's baseline example, where dock and delay allowance sits at 15% and the headline result is 16.61 min, this scenario comes in 1.74% above the baseline at 16.9 min.
- A figure at this level is achievable when dock and delay allowance is genuinely sustained, not just peaked for a shift. A single average rate misses reality for damaged, mixed-SKU, or floor-loaded trailers that need hand-sorting before pallets can move.
