Yard management: the queue you own and rarely measure

The ground outside is a buffer with a price

Holding vehicles in the yard smooths arrivals against the pace at which doors can work, which is genuinely useful. It stops being useful when the yard becomes the default answer to a congested building, because every hour a vehicle stands may be chargeable, and because a full yard blocks the manoeuvring space that makes the doors work at all. The size of the yard, in effect, sets how much unevenness the site can absorb before the road outside becomes the overflow.

Knowing what is actually out there

Control begins at check-in: which vehicle, whose trailer, carrying what, sealed or not, loaded or empty, and where it has been parked. Recording that against a marked bay position, and updating it as the trailer moves, is what turns the yard into an inventory rather than a car park. Sites without it spend a surprising share of the shift walking the yard looking for a trailer that somebody moved.

Shunting is a scheduled job

Moving trailers between parking, doors and the gate is real work with a queue, and a busy site benefits from a dedicated machine and driver rather than borrowing whoever is free. The move list should be prioritised by what the doors need next, not by the order in which requests arrived, which means the person controlling doors and the person controlling moves need to be working from the same picture. Where shunting is treated as a favour, doors wait.

The gate is a security control

The perimeter is where identity is checked, where seals are inspected and recorded, and where unauthorised access is prevented, and it is also the point at which most losses could have been stopped. Practical controls include verifying the driver and the collection against the booking, checking seals against the paperwork on both entry and exit, keeping pedestrians out of vehicle areas, and having a defined procedure when something does not match. Recording the check is what makes it useful afterwards.

When trailers quietly become storage

Using loaded trailers to hold stock during a peak is a common expedient and an expensive habit. The equipment is not designed as a store, the goods are less secure and less accessible, temperature-sensitive product may be at risk once the unit stops running, and standing charges accumulate under the transport contract. Where it is used deliberately, it belongs in the capacity plan with an agreed limit and a date by which the goods will come inside.

Frequently asked questions

What is the first sign that a yard is out of control?

Time spent looking for trailers. When loaders ask where a unit is, or a shunter searches bay by bay, the record has stopped matching the ground, and door productivity will already be suffering even if nobody has attributed it yet.

Should pedestrians ever cross the yard?

Only on defined, marked routes with clear separation from vehicle movements, and drivers should have a designated waiting area rather than wandering to find a supervisor. Mixing people and manoeuvring vehicles is among the most serious hazards a logistics site carries.
