• Finally, for a given route and schedule the number and types of
parts to be loaded per tugger tour need to be determined (DL2-
loading). OEMs aim at a JIT loading plan, so that exactly the number
and types of parts being consumed by the stations to be served
during two successive stops are loaded on a tugger’s wagons. However,
considering the limited capacity of a tugger such plans might
not always be feasible and preceding tours have to deliver additional
parts. In the resulting decision problem inventory at the stations
should be reduced, while given station demands and limited
tugger capacity are considered as constraints. Again, this problem
is heavily interdependent with the former two problems, although,
in practice, they are typically solved sequentially.
