U.S.-Chile: Solution Approaches to Forest Management Problems

小行星9314779 该美洲计划奖将支持宾夕法尼亚大学的Monique Guignard- Spielberg博士和智利大学的Andres Weintrab博士进行研究合作，为北美和智利森林的管理问题设计有效的解决方法。 中期至长期综合管理决策，如木材砍伐、修建通道、木材运输等，必须在存在环境制约因素（如野生动物栖息地和砍伐区）的情况下做出。 研究结果将提供更好的工具，设计有效的解决方法，面对这些限制，并将推进最先进的解决硬组合规划问题。 有效管理自然资源在全世界变得越来越重要，特别是在智利，智利拥有强大的林业。 在该项目中，智利方面将专注于生态学以及与森林环境密切相关的特殊代码的设计和开发，而美国方面将专注于高效建模，通过拉格朗日技术获得整数最优值的严格界限，并设计拉格朗日生态学。 ***

9314779 Guignard-Spielberg This Americas Program award will support Dr. Monique Guignard- Spielberg, of the University of Pennsylvania, and Dr. Andres Weintrab, of the University of Chile, in a research collaboration to design efficient solution methods for management problems in North American and Chilean forests. Medium to long range integrated management decisions, such as timber cutting, building of access roads, timber transportation, and others, must be made in the presence of environmental constraints such as wildlife habitats and cutting areas. Research results will provide foresters with better tools for devising efficient solution methods in the face of these constraints and will advance the state of the art in solving hard combinatorial programming problems. Efficient management of natural resources is becoming increasingly important around the world and in Chile in particular, with its strong forestry industry. For this project, the Chilean side will focus on heuristics and the design and development of special codes intimately bound to the forestry environment, while the U.S. side will concentrate on efficient modelling, obtaining tight bounds on the integer optima via Lagrangean techniques and designing Lagrangean heuristics. ***
