Substantial climate change impacts threaten the persistence of cultural resources globally. The need exists for conceptualizing decision support tools that focus on quantifying and optimizing the managerial priorities to leverage historic preservation and adaptation actions that enhance the continuity of heritage values and sites. Informed by the Structured Decision Making (SDM) approach, this study advances the singular objective Optimal Preservation (OptiPres) Model, a decision support tool for climate adaptation planning of historic buildings by considering three tourism management objectives: (a) maximize accumulated resource value, (b) maximize cost-efficiency, and (c) minimize vulnerability. These objectives are tested under different budget scenarios using a 30-year planning horizon with a subset of buildings located in two historic districts of Cape Lookout National Seashore (CALO), United States. The multi-objective approach demonstrates the OptiPres Model is transformative, transparent, and transferable for providing cultural resource decision support and enhancing the sustainability of cultural heritage globally.

重大的气候变化影响威胁着全球文化资源的持久性。需要将决策支持工具概念化，重点是量化和优化管理优先事项，以利用历史保护和适应行动，增强遗产价值和遗址的连续性。在结构化决策（SDM）方法的指导下，本研究通过考虑三个旅游管理目标，推进了单一目标最优保护（OptiPres）模型，这是一种历史建筑气候适应规划的决策支持工具：（a）最大化累积资源价值， (b) 最大限度地提高成本效益，以及 (c) 最大限度地减少脆弱性。这些目标在不同的预算情景下使用 30 年的规划范围进行测试，其中一部分建筑物位于美国 Cape Lookout National Seashore (CALO) 的两个历史街区。多目标方法表明 OptiPres 模型具有变革性、透明性和可转移性，可提供文化资源决策支持并增强全球文化遗产的可持续性。
