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.

Aeronautics for Introductory Physics’ approach to contextual physics teaching and learning does not rely upon building mental models that are unique to flight – rather, it is founded on the ideas of traditional physics instruction, paralleling the
A student will slide a disk of mass mdisk toward the rod with velocity v0 perpendicular to the rod, and the disk will stick to the rod a distance x from the pivot. The student wants the rod-disk system to end up with as much angular speed as possible.
