The problems facing forest companies have become significantly more complex for several reasons: (1) management for environmental resources involves impacts on processes with varying time and spatial scales; (2) protection and enhancement of many environmental values require optimization of spatial configurations hence involving very large problems; (3) the management for multiple values involves more complex sets of constraints and objectives; and (4) lack of information (e.g. lack of precise data) and knowledge (e.g. uncertainty with respect to long term biological impacts) increase the importance of treating risk and uncertainty explicitly. In addition to facing complex choices of silvicultural strategies, many forest companies must cope with interference in their forest arrangement from "overlapping" tenure holders which have rights to exploit other resources on the same forest. The objective of our research program is to develop models that will assist both industry and government to find optimal management strategies that take explicit account of the institutional arrangements that regulate forest operations. We plan to develop more efficient algorithms to identify optimal spatial assignment of land use activities using new institutional designs (e.g. zoning). We also plan on refining these models to include the potential impacts of significant natural processes (fire, succession). An important issue facing many forest companies is the issue of overlapping tenures. Governments often provide the rights of using different resources on forest lands to different companies. For example, different companies are assigned rights to different resources (e.g. forestry and oil and gas). The exploitation of different resources on the same land by different companies can lead to conflict and significant waste if done without coordination. We plan to model the decisions facing forest companies under different overlapping tenure regimes and explore a variety of cooperative joint planning options. We will consider a variety of alternative distributional mechanisms (cost-sharing mechanisms) to identify a fair distribution of payoffs and costs among the tenure holders. The models will be tested through a sequence of case studies in Ontario, BC and Alberta.

由于以下几个原因，林业公司面临的问题变得更加复杂：（1）环境资源管理涉及不同时间和空间尺度的过程影响； （2）很多环境价值的保护和提升需要优化空间配置，涉及的问题非常大； (3) 多重价值管理涉及更复杂的约束和目标； (4) 缺乏信息（例如缺乏精确数据）和知识（例如长期生物影响的不确定性）增加了明确处理风险和不确定性的重要性。除了面临造林战略的复杂选择之外，许多林业公司还必须应对有权开发同一森林上其他资源的“重叠”土地使用权持有人对其森林安排的干扰。我们研究计划的目标是开发模型，帮助行业和政府找到最佳管理策略，明确考虑监管森林经营的制度安排。我们计划开发更有效的算法，以使用新的制度设计（例如分区）来确定土地利用活动的最佳空间分配。我们还计划完善这些模型，以纳入重要自然过程（火灾、演替）的潜在影响。许多林业公司面临的一个重要问题是权属重叠问题。政府经常向不同的公司提供使用林地上不同资源的权利。例如，不同的公司被分配对不同资源（例如林业、石油和天然气）的权利。如果不协调，不同公司在同一土地上开发不同资源可能会导致冲突和严重浪费。我们计划对林业公司在不同的重叠权属制度下面临的决策进行建模，并探索各种合作联合规划方案。我们将考虑各种替代分配机制（成本分摊机制），以确定权属持有人之间收益和成本的公平分配。这些模型将通过安大略省、不列颠哥伦比亚省和阿尔伯塔省的一系列案例研究进行测试。
