I'd imagine that like weather predicting, the best way to simulate a complex system is to slightly vary the starting conditions and sample the results. Obviously it's not going to be perfect, but it gives a clear idea about what things to worry about. Reading the article, it seems that the purpose of the twin isn't simulation, it's mapping. That data can then be used as the input to simulation of your choice.
