...A/F
Ratio of actual to forecasted demand. A ratio of 0.5 means that only 50% of what was forcasted came in as actual orders. A/F = 0.75 means that 75% of forecasted orders came in, A/F = 1 that 100% came in, and so forth. This is true for all three products.

...uncertainties
Exept for scrap rates in the workstations. These are set to a certain percent, i.e. each unit leaving a station has this percent change of being scrapped. This uncertainty has little impact on the results of the simulation.

...times
The reason for this is that certain assumptions must be made regarding the future sharing of common ressources in production. A more powerful algorithm would probably do a better job, but there is reason to believe that the uncertain future makes it impossible to quote 100% correctly.
