1 Ιουλ 2015 · The air-cargo consolidation problem under the pivot-weight scheme (ACPW) is characterized by a pivot weight and two unit costs, respectively, the under-pivot rate and the over-pivot rate. The pivot weight Uj is a weight threshold of a ULD, below which the cargo is charged the under-pivot rate.

1 Ιουλ 2015 · We formulate a mixed integer program, and propose four solution methodologies for the air-cargo consolidation problem under the pivot-weight scheme (ACPW). These are exact solution approaches based on branch-and-price, a best-fit decreasing loading heuristic, and two extended local branching heuristics (a multi-local tree search and a ...
Simply put, pivot weight refers to the minimum chargeable weight for a specific type of container or Unit Load Device (ULD) used in air cargo. Shipments that fall below the pivot weight for a particular ULD are charged a higher rate per kilogram, known as the under-pivot rate.
The air freight volumetric weight, or dimensional weight, is an estimated weight value based on a package’s length, width and height. It is a theoretical weight calculated using a minimum air cubic conversion factor chosen by the freight carrier.
31 Ιουλ 2015 · In this problem, customer's individual unit load devices (ULDs) are charged a penalty cost if the loaded weight fails to fall within an acceptable range; this penalty incentivizes proper...
A Unit Load Device (ULD) is either an aircraft pallet and pallet net combination, or an aircraft container. ULDs are removable aircraft parts subject to strict civil aviation authorities’ requirements from design, testing, production, and operations, to repair and maintenance.
Pivot Weight. To avoid companies stretching the regulation maximum capacity weight of a Unit Load Device (ULD), freight companies may charge for shipments that exceed limits - this threshold is called the pivot weight. Chargeable Weight.
