Minimizing Investment in Residual Growing Stock for an Uneven-aged Stand with a Target Basal Area Constraint—An Approach

The problem of minimizing the investment in after-cut residual growing stock for an uneven-aged stand subject to a target basal area is formulated and solved as a non-linear optimization model using the Lagrangian approach. The model leads to the determination of an optimally balanced diameter distribution for the residual growing stock and provides information about how sensitive capital investment is concerning changes in the basal area constraint. The procedure is flexible and allows for sensitivity analyses given changes in parameters.
