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 ...
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. We propose a solution methodology based on Lagrangian

1 Ιουλ 2015 · A mixed-integer linear programming model is presented and a heuristic for solving the multi-period freight consolidation problem for a third-party logistics provider that transships multiple products from multiple suppliers to a single end customer is proposed.
international air cargo business, shipments are usually consolidated into containers; those are the ULDs. A ULD is charged depending on whether the total weight exceeds a certain threshold, called the pivot weight. Shipments are charged the under-pivot rate up to the pivot weight. Additional weight is charged at the over-pivot rate. This scheme ...
