The transportation network manages product delivery. There are several different kinds
of transportation networks: direct shipping, milk runs, crossdocking and tailored networks
The direct shipping network delivers products from suppliers to their customers. Apparently,
if a shipment consists of a full truckload, it is economical to ship directly from the seller to the buyers.
However, when orders are less than a truckload (LTL), the other three approaches can be considered. For
example, the milk run transportation network shares vehicles among either suppliers or customers, since
any individual order cannot fill a full truck
