Abstract:
Identifying optimal harvesting (thinning and clearcutting) schedule for a forest stand (stand-level) is of great importance to forest managers and researchers. However, providing highly reliable optimal harvesting schedules still requires considerable computation time. This study aimed to develop a simulated-annealing-based method to provide a highly reliable optimal schedule for harvesting in a short time. In practice, the optimal number of harvesting events in a rotation may not be large. Therefore, 1) treating harvesting ages as well as the thinning intensity as control variables, and 2) searching the optimal number of thinning events iteratively, the dimension of the scheduling problem was virtually reduced. The method was developed through a comparison with a reliable method for a model with fixed harvesting ages.
