1 lip 2015 · In the international air cargo business, freight is usually consolidated into containers, called Unit Load Devices (ULDs). The transportation charge of a ULD depends on whether the total weight exceeds a certain threshold, called the pivot weight.
1 lip 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.
