The choice of the optimal sawtimber harvesting system (a theoretical approach based on mathematical programming)

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...

Development and comparison of stand-level bucking optimization methods

Creator:: Laroze, André J.
Abstract:: Heuristics based on Monte-Carlo Integer Programming (MCIP) and Tabu Search (TS) techniques were developed for generating easily implementable bucking rules that are applicable to entire stands (as opposed to individual stem classes), and for selecting the rule-set that provides the best feasible solution (given log prices and market constraints). A...

Linking a growth model with logging production costing

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...

LOGCOST a harvest cost model for southwestern Idaho

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...

A method to improve consumer surplus estimates from truncated recreation demand data

Creator:: Weidner, Kerri L
Abstract:: A method is presented in this study for improving empirical travel cost analyses when truncated data are available. The analysis expands upon a Monte Carlo study conducted by Riyadi (1993) which compared the coefficient and consumer surplus estimates for five travel cost estimators using both truncated and censored data. Riyadi...

Countertrade, a transaction costs approach

Creator:: Kelly, Sharon
Abstract:: New types of exchange arrangements are becoming increasingly popular for a wide range of goods traded internationally. Several types of countertrade arrangements have been identified, ranging from pure barter to more elaborate schemes where only a portion of the trade is "paid for" in goods, including bilateral trading agreements with...

Integrating learning from examples into the search for diagnostic policies

Creator:: Oregon State University. Dept. of Computer Science, Bayer-Zubek, Valentina, and Dietterich, Thomas Glen
Abstract:: This paper studies the problem of learning diagnostic policies from training examples. A diagnostic policy is a complete description of the decision-making actions of a diagnostician (i.e., tests followed by a diagnostic decision) for all possible combinations of test results. An optimal diagnostic policy is one that minimizes the expected...

Modeling biomass transport on single lane forest roads and monitoring GPS accuracy for vehicle tracking under different forest canopy conditions

Creator:: Simwanda, Matamyo
Abstract:: The transportation of wood and biomass resources from landing and other collection locations to processing and distribution sites is a substantial cost within the wood supply chain. These high costs provide a basis for research aimed at improving biomass transportation planning decisions and potentially reducing biomass transportation costs. Chip vans...

A method of selection of cable harvesting machines for Vermont

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...

Monte Carlo study of several methods for estimating linear demand for outdoor recreation from censored and truncated data

Creator:: Riyadi, Dedi M. M. (Dedi M. Masykur)
Abstract:: Objective of this study was to compare accuracy of several travel cost methods, by employing Monte Carlo simulations in the single site framework. Estimates from five methods were compared to the "true" travel cost coefficient and "true" consumer surplus. Each method was ranked, using the root mean squared error (RMSE)...
