Decision problems in the Forest Products Industry are complex to optimize for several reasons. First, some problems are difficult to solve from a combinatorial point of view and require advanced optimization techniques. Other decision problems involve constraints that are difficult to model, constraints expressed in terms of qualitative preferences, or constraints only expressed by the expert when faced with a tentative solution. Other decision problems are hierarchically decomposed or structured as organizational silos, which involve several decision sub-problems that are complex to coordinate. Yet other decision problems involve collaborative or joint decision processes which involve several stakeholders, many objectives and preferences to tradeoff, as well as private information and constraints to satisfy.

由于多种原因，林产品行业的决策问题很复杂，难以优化。首先，有些问题很难从组合的角度解决，需要先进的优化技术。其他决策问题涉及难以建模的约束、以定性偏好表达的约束或仅由专家在面对暂定解决方案时表达的约束。其他决策问题被分层分解或结构化为组织孤岛，其中涉及多个难以协调的决策子问题。然而，其他决策问题涉及协作或联合决策过程，其中涉及多个利益相关者、需要权衡的许多目标和偏好，以及需要满足的私人信息和约束。
