Less-than-truckload shipping or less than load (LTL) is the transportation of an amount of freight sized between individual parcels and full truckloads. [1] Parcel carriers handle small packages and freight that can be broken down into units less than approximately 150 pounds (68 kg). Full truckload carriers move entire semi-trailers. Semi ...
At any given time, 14 different aircraft are designated at 7 UPS Airlines hubs, equalizing flight distance and time between locations. Four of the six aircraft types flown by the airline are used for hot-spare service (excluding the 747-400 and 747-8).

The spoke–hub distribution paradigm (also known as the hub-and-spoke system) is a form of transport topology optimization in which traffic planners organize routes as a series of "spokes" that connect outlying points to a central "hub".
A map that attains this infimum (i.e. makes it a minimum instead of an infimum) is called an "optimal transport map". Monge's formulation of the optimal transportation problem can be ill-posed, because sometimes there is no T {\displaystyle T} satisfying T ∗ ( μ ) = ν {\displaystyle T_{*}(\mu )=\nu } : this happens, for example, when μ ...
Route capacity is the maximum number of vehicles, people, or amount of freight than can travel a given route in a given amount of time, usually an hour. It may be limited by the worst bottleneck in the system, [ 1 ] such as a stretch of road with fewer lanes. [ 2 ]
The minimum distance d is the distance along a great circle that runs through s and t. It is calculated in a plane that contains the sphere center and the great circle, , =, where θ is the angular distance of two points viewed from the center of the sphere, measured in radians.
