Check out this case study for a coal handling and processing plant model built using ExtendSim. The intent was to be able to test operational strategies for run-of-mine. There were business rules for the three stockpiles and also for the stacker-reclaimer. Maintenance and weather impacts were modelled. Output priorities for product could also be changed, ie train or overland conveyor.
Major required enhancements were changes to business rules and routing for trains and information outputs for many key metrics.
