Abstract

In railway simulation, given timetables have to be checked against various criteria, mainly correctness and robustness. Most existing approaches use classical centralized simulation techniques. This work goes beyond that in two main aspects: We use constraint satisfaction to get rid of deadlock problems and the simulation is done distributedly for better performance. This should make it possible to solve very large railway simulation problems.
