Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Occupied door-hours (door·h)

Door hours with a trailer occupying the door; overlapping use or inconsistent capacity bases can produce values above available hours.

Available door-hours (door·h)

Total scheduled door-hours available in the same period.

Compute dock-door utilization as occupied door hours over available door hours. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Utilization (%)

Occupied door-hours as a percentage of available door-hours.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.
