; Random Seed : Treatments are basically assigned in priority order. It is possible to let the system enforce deviation from this order by, with a certain probability, skipping a treatment for a treatment unit and go to the next unit in the priority list. The reason for doing this is to account for non-predictable behaviour, since not all forest owners are following the "management handbook". This means that two identical scenarios (i.e. identical assumptions and input data) will give different results, which sometimes makes conclusions difficult to draw. Setting the random seed to a number larger than 0 will give the same result for two identical scenarios.

; Normal Production : Function parameters for the so called Normal Production. This function is essentially a stand-level growth function. It is not used in growth calculations but only in RegWise to determine the distribution of growth over a rotation. The result is used to determine thinning volume targets based on stand age, in combination with (so far) a pre-defined distribution of the accumulated amount of thinning in a stand at a certain age.

This control table is specific and essential for RegWise and contains settings for determining harvest levels in scenarios and priority functions for allocating activities to treatment units. Scenario Settings is used instead of the Treatment Program Generator control table in PlanWise - while the Treatment Program Generator generates a variety of alternative treatment programs to each treatment unit (to enable optimization) RegWise creates only one specific treatment program for each treatment unit.

For usage, see Helpdoc.
