Operations Research in Forest Harvesting
Operations research techniques such as mathematical programming, simulation, and the development of planning systems can contribute to decision-making in forestry management. Computers have dramatically changed the possibilities and practice of data collection, storage, analysis, and presentation but the difficulty of obtaining access to them has until recently limited their use. Development of...

متن کاملland use planning for forest management for multiple use (harvesting, ecotourism and protection) (case study: patom district of kheyrud forest )
nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. the study area is patom district of...
متن کاملHarvesting Small Trees and Forest Residues
Eight countries collaborated and shared technical information on the harvesting of small trees and forest residues in a three year program. Proceedings and reports from workshops and reviews are summarized in a review of activities and harvesting systems of the participating countries. Four databases were developed for harvesting and transportation of these materials.
متن کاملThinning and Harvesting in Stochastic Forest Models
This paper analyzes a stochastic forest growth model in which the manager is able to first thin the forest to promote better growth before harvesting. Both Wicksell single thinning-andharvesting cycle and Faustmann on-going rotation problems are considered. The Wicksell problem is analyzed by first restricting the class of decision times to (thinning,harvesting) pairs that bound the growth away...
