Five antithetic pairs of simulation replications have been executed. Preliminary
output shows that the simulated average of the combined lignite and waste volume
is in very good agreement with the actual one. The differences range from -4.3 %to 2.5 %. Still, a refinement of the model in regard to the interaction among the
processes for the selection of material type, the BWE advance, and the selection
and implementation of the excavated material conveying sequences, is needed.
