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-cargo consolidation problem with pivot weight: Models and solution methods
Positional weight (pivot weight) is a conditional weight based on ULD (unit load device) dimensions. It is based on the minimum established weight of a ULD and differs from airline to airline.
18 Φεβ 2023 · For each container type, a minimum weight (pivot weight) is taken as a basis, which is charged regardless of the actual weight. If the actual weight is above this minimum, a surcharge per pound or kilo is levied for the difference ( over pivot weight ).
The cost of using a ULD consists of a fixed charge and depends on the weight of the cargo it contains. A ULD is charged at an under-pivot rate if the total weight is below a threshold limit, called the pivot-weight. Additional weight is charged at the over-pivot rate.
