Abstract
Integrated scheduling of intermodal transport operations within global supply chains combines flexible land transport schemes with overseas transport running a given timetable. This paper proposes a heuristic scheduling method based on the construction of a cost-weighted graph for each shipment, containing only feasible paths regarding time and capacity. In this way, the scheduling task is formulated as a shortest path problem which can be solved in polynomial time by the well-known Dijkstra’s algorithm. The approach is also suitable for larger problem instances, which is demonstrated by means of an example scenario.
