We have chosen to divide the problem descriptions into three domains: transport, traffic, and
terminal. A transport is an activity where something is moved between point A and B by one
or several modes of transport. Problem areas that fall under the category transport are e.g., route
planning, fleet management, different sorts of scheduling, i.e., functionalities that takes place to
support transportation.
While transport refer to the movement of cargo from one point to another, traffic refers to the
flow of different transports within a network. One train set is thus a transport, or part of a transport,
that takes part in the train traffic flow. Hence, a transport can be part of several traffic networks
(air, waterborne, road, rail) and a traffic network constitutes of several transports. Typical
traffic activities are traffic flow scheduling such as railway slot allocation, air traffic management,
and railway traffic management.
Within for example a transport chain where the cargo is transported by truck, rail, ship, and
truck again, there are interfaces between the different modes. These interfaces represent nodes
for reloading and are referred to as terminals. Terminals can be any fixed place where the cargo
is handled and require access to different kinds of resources. Typical terminal activities are resource
allocation and scheduling of cranes, forklifts and parts of a facility.
