Creator:: Mikkonen, Esko
Abstract:: An extension of the sensitivity analysis of linear programming, called parametric programming is used in determining optimal sawtimber logging system mix. The five logging systems under study are manual log-length, system, log-length processor and harvester systems, manual tree-length system and tree-length harvester system. In conditions where it is not exactly...

Creator:: LeDoux, Chris B.
Abstract:: Helicopter yarding systems have become a popular tool in removing timber from steep slopes, sensitive soils, limited access areas, and environmentally sensitive stands. Little is known about the system's dynamics. This study is part of a research project to explore "advanced" logging systems as to their economic efficiency and environmental...

Creator:: Giles, Robert Steven
Abstract:: LOCCOST is an interactive computer program that predicts stump to mill logging costs, stumpage and net present value of a harvest based on stand data, pond value and logging parameters, entered by the user. The program is intended for use by foresters to evaluate the economics of different stand management...

Creator:: Bergan, Ernest E.
Abstract:: A model (called MERLIN) is presented that can allow the resource manager to consider the combined effects of silvicultural treatments and their effect on expected logging production and costs. This integrated analysis takes place within the framework of personal computer software readily available to most managers. This integration is accomplished...

Creator:: LeDoux, Chris B.
Abstract:: Strip thinning is recognized as a way of commercial thinning young-growth stands. strip thinning has been used worldwide. The purpose of this study was to explicitly evaluate the costs and benefits associated with skyline strip thinning in young Douglas-fir (Pseudotuqo menzesii Franco) stands in the Pacific Northwest and to compare...

Creator:: Nickerson, Devon B.
Abstract:: A problem of interest to forest managers is the optimum arrangement of truck roads and landings for economical logging operations. This problem becomes more complex if,a combined yarding and swinging operation is considered. I,t is possible to formulate a mathematical model to express the cost per unit volume for a...

Creator:: Stirler, Dennis John
Abstract:: There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method. The method chosen for this paper is made up...
