Domain-specific

• Transshipment
  • Second, it changes the geometry of feasible network designs: because transshipment at a hub can consolidate flow from many origins and disaggregate it to many destinations, a hub-and-spoke network is cheaper than a full point-to-point mesh once origin-destination flow density drops below the break-even threshold for a direct service.

    This sourceHub consolidation economics and the flow-density threshold at which routing through a hub beats direct point-to-point service.

Mechanisms

• Relay Hub Network
  • It is the logistics principle of hub-and-spoke consolidation

    This sourceFormulates the hub-location problem underlying hub-and-spoke consolidation through selected hub facilities.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
