There are a plethora of acronyms and terms commonly used within logistics and supply chain, below is a list of those specifically relevant to this on-line resource:

Term

Acronym

Definition

Advanced Shipment Notification

ASN

An electronic notification of pending deliveries like an electronic packing list, and usually sent through Electronic Data Interchange (EDI). The goal is to provide information to the receiving warehouse operation well in advance of physical delivery. By providing a list of all of the bar-coded ID numbers of the shipping units and the contents of each, the scanning of the pallet labels can facilitate a quick and efficient good receipt process.  For more information visit GS1
 

Backhaul

Generally a backhaul is any return load taken after the delivery has been made. An example of this would be the collection of supplier loads from a supplier's premises by a retailer for delivery into the retailer’s own RDC.
 

CanBus

Controller area network. A high speed communications network designed to support control functions between electronic devices distributed throughout the vehicle.
 

Computerised Vehicle Routing and Scheduling

CVRS

Integrated technology systems solutions for transport fleet management, often providing real-time data for improved supply chain visibility and fleet productivity.
 

Cross Dock

A system where products for store orders are not put away into the warehouse racking to be picked later, but they are processed into store orders either by the supplier or on arrival at the RDC. This can entail breaking down the inward delivery into store ready consignments or if the consignments are pallet sized moving the pallets across the docking area for loading onto the store delivery vehicle. This movement of product across warehouse vehicle docking bays gives the process its name.
 

Distribution Centre

DC

A warehouse that is the sole stocking point for the distribution system that it services.
 

Double Decker

Double-deck trailers are semi-trailers with either a fixed, hinged or moveable (floating) second floor, which enables them to carry more palletised goods. In general, a double decker can carry 40 pallets as opposed to 26 pallets for a standard trailer.
 

Drag

The retarding force exerted on a moving vehicle by the air around it. This is often referred to as air resistance.
 

Drop deck trailer

A drop-deck trailer is a trailer on which the floor drops down a level once clear of the tractor unit. The most common types of drop-deck trailer are flatbeds and curtain sided.

5PL

A key function of the 5PL is to aggregate the demands of the 3PL into a bulky volume for negotiating more favourable rates with airlines and shipping companies regardless of which generation of logistics solution belongs to all.
 

Fourth Party Logistics Company

4PL

Will directly provide many of the supply chain operations and be an asset owner. They may have some geographical limitations and thus employ 3PLs for some operations.

Standardised as part of the GSM phase 2 development, represents the first implementation of packet switching within GSM, which is essentially a circuit-switched technology. Rather than sending a continuous stream of data over a permanent connection.
 

Geofence

Virtual perimeter encompassing an area in a vehicle tracking or transport management system. If a vehicle equipped with GPS either passes or leaves the geofence, the vehicle tracking or transport management system can record a timestamp or trigger a process such as an automated message or interface to another system.
 

Global Positioning System

GPS
