Comparing Adjacency Constraint Formulations for Randomly Generated Forest Planning Problems with Four Age-Class Distributions

摘要

Three types of adjacency constraint formulations-pairwise, Type I ND (nondominated), and NOAM (new ordinary adjacency matrix)-were compared on 900 hypothetical, randomly generated, spatially explicit forest management problems with between 50 and 350 stands. Forests were generated using four age-class distributions, nominally called immature, regulated, overmature, and old-growth. Management planning problems with adjacency constraints were formulated for these forests in Model 1 format based on planning horizon consisting of three 20 yr periods.
