Abbildung von Infrastrukturkosten in der Eisenbahnbetriebssimulation

When dimensioning installations, the discipline of railway operations research is increasingly having to include the costs of infrastructure throughout the whole of its service life. This is an aim that can only be attained if cost-evaluation elements are integrated in the models produced by railway operations research. It has to be possible to give consideration to the various components of infrastructure costs (depreciation, interest payments and maintenance) in order to be able to weigh up different forms of financing. The authors take the example of a planning and simulation tool called RailSys® to show how a module for computing all the components of life-cycle costs can be added to such a program system. This is done by adding technical attributes to the modelled data structure with its vertices and edges. In , order to avoid having to capture all this data manually (which is very labour-intensive), procedures have I been introduced to permit the standardized and automated assignment of data, while still guaranteeing a good level of precision. The detailing in the emulation and the computation are based on both the influence of the overall costs and the data underlying the railway operational simulation. With this addition to the planning system, it is going to be easy in future to determine and operate an optimally dimensioned and favourably-priced infrastructure.
