Abstract A few weeks ago, Mr. Schlechte presented a modeling approach for railway capacity allocation based on mathematical programming. The formulation of an optimisation problem in a mathematical programming language makes standard solving techniques applicable (commercial and non-commercial solvers).

Object-oriented modeling approaches are applied in various decision support tools and facilitate the translation of expert knowledge into a problem formulation. Unfortunately, such a representation is not necessarily well suited for problem solving techniques.

This work-in-progress talk intends to compare some aspects of both modeling approaches and proposes a versatile solving technique for an object-orientated representation of the railway capacity allocation problem.
