Uniform doors and service times. Arrival peaks, waiting time, labor, and door compatibility require separate analysis.
BEHIND THE NUMBER
How the calculation works
Service and turnover must be non-overlapping time when a door is unavailable to another truck. The utilization ceiling is an entered planning assumption, not a queueing guarantee. Each door has the same opening hours and can serve the same truck types. The result rounds up to a whole number of doors.
Door workload = trucks x (service + turnover minutes); required doors = ceil(workload / (open hours x 60 x utilization / 100))
When this calculation helps
Door capacity depends on usable time and an entered service duration per truck. Compare workload over the same period rather than dividing a daily truck total by an hourly rate.
Check the interpretation
Average door capacity does not ensure an appointment schedule is feasible. Arrival bunching, different trailer types, yard constraints, and unavailable doors can create queues despite apparent daily headroom. Review the peak window before reducing coverage.
Average workload does not cover arrival peaks, queues, appointments, labor or equipment shortages, or incompatible door types. Model peak time windows separately and validate a real dock schedule before making capacity decisions.
Good to know
Does this predict truck waiting time?
No. Waiting depends on arrival patterns, service variability, appointment rules, and resource constraints. This calculation only divides occupied-door workload by planned available capacity.
Should I include time in the yard?
Only include time that actually occupies the dock door. Yard waiting before door assignment is not door workload.
