一个动态的，确定性的过程，聚合成较大的收获块的个别森林经营单位，允许模拟的管理行为，支持在美国西部俄勒冈州的森林政策的合理描绘的发展。这里描述的方法动态地将各个管理单元聚合成收获块（战术目标），然后将块拟合到可变（用户定义的）明确的大小分布（战略目标）。这项工作的一个重要目标是，管理行为（聚合方法和最近的清除的大小分布）是建模或模拟，而不是优化，用于政策分析的目的。根据木材资源的估值以及确定采伐区块的大小是否符合皆伐规模分布，选择管理单位进行皆伐采伐，并将其列入采伐区块。管理行为的密切代表有助于决策者和土地所有者评价现行政策的替代办法，并在执行森林政策之前开始“仔细考虑”这些政策。
A dynamic, deterministic process for aggregating individual forest management units into larger harvest blocks was developed to allow a simulation of management behavior in support of the development of reasonable portrayals of forest policies in western Oregon, USA. The method described here dynamically aggregates individual management units into harvest blocks (a tactical goal), and the blocks are then fit to a variable (userdefined) clearcut size distribution (a strategic goal). One important objective with this work is that management behavior (the method for aggregation and the size distribution of recent clearcuts) is modeled or simulated, not optimized, for policy analysis purposes. Management units are selected for clearcut harvest and included in harvest blocks based on a valuation of the timber resource, and a determination of whether the size of the block is consistent with a clearcut size distribution. A close representation of management behavior facilitates a process whereby policy makers and landowners can evaluate alternatives to current policies, and begin to "think through" forest polices prior to implementing them.
