It's a pipeline. Check out this [1] paper about the Taco Bell scheduling system. It's forecasting (stats, but would probably be called ML if paper wasn't in 1998) -> queuing theory (markov chains, sometimes formula-based, sometimes simulated) -> scheduling (normally mixed integer linear programming) [1] http://pubsonline.informs.org/doi/abs/10.1287/inte.28.1.75 http://pubsonline.informs.org/doi/abs/10.1287/inte.28.1.75
