The interstate rail network in Australia is mostly single-line track, with occasional crossing loops to allow trains to pass or overtake. It is therefore important to coordinate the movements of trains. Train plans are traditionally developed manually, and it can take many weeks to develop a single feasible plan. Researchers at CIAM have spent many years developing methods and tools to automate scheduling trains and maintenance on railway networks. These scheduling problems are too large and too complex to be tackled by mathematical programming techniques; instead, we have developed practical solution techniques using network search heuristics, genetic algorithms, Problem Space Search, and Cross Entropy Optimisation.
We have also applied similar techniques to crew rostering and to the scheduling of truck movements in underground mines.
