A model for the determination of optimum setting dimensions for tractor yard/swing operations

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...

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...

A simulation of the comparative costs and benefits of skyline strip thinning

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...

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...

Simulation of mechanized log harvesting systems

Creator:: Wiese, Christoph
Abstract:: The focus of this research is to develop a personal computer based simulation model of the mechanized logging process, from felling until the log arrives at the sawmill. The SLAM II simulation language is used for modeling, and the main emphasis is on the overall performance of this system, and...

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...

Optimization of cable logging layout using a heuristic algorithm for network programming

Creator:: Chung, Woodam
Abstract:: Designing timber harvesting units is a challenging task. The task requires decision making on logging equipment, landing site, cable road profile, road location, and transportation system. Traditionally forest planners have done the task manually. However, the manual method makes it difficult to examine many alternatives and the harvest plans depend...

Mathematical model for determining the position and line tensions for a tethered logging balloon

Creator:: Avery, Robert B.
Abstract:: A program was developed on a desktop computer to determine the cable tensions and position of a balloon tethered by two or more guylines. The program was specifically applied to the analysis of the static load lifting capability of the Pendulum Swing Balloon System. This system uses a tethered balloon...

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...

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

A coupled hydrologic-geomorphic model for evaluating effects of vegetation change on watersheds

Creator:: Duan, Jinfan
Abstract:: This work describes the modeling framework and initial results for CLAWS (Coupled Landscape And Water System), a physically-based, spatially-distributed hydrologicgeomorphic model that has been coupled with a vegetation dynamics simulation. Spatial variability of topography, soil, vegetation, and climate drive a hydrology module that calculates the water budget at given time...

A multivariate control solution to the mixed species/diameter class thinning and final rotation problem

Creator:: Cousar, Paul K.
Abstract:: The algorithm RLS-PLUS was developed to yield solutions to the multivariate control problem of diameter and species optimization for mixed conifer and hardwood stands. The problem is specified with twenty-five state variables consisting of five species groups with four merchantable diameter classes and one unmerchantable class. This gives twenty diameter...

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)...

Using a heuristic programming method for incorporating wildlife habitat constraints into spatial harvest scheduling on the Elliott State Forest

Creator:: Lennette, Marie
Abstract:: The Elliott State Forest, located in the Coast Range of Oregon, is currently revising their Habitat Conservation Plan (HCP). Many of the constraints in the HCP are spatial, requiring identification of specific parcels in order to limit activity along habitat reserves, limit harvest opening size, and to coordinate activities within...

Local and downstream effects of contemporary forest harvesting on streamflow and sediment yield

Creator:: Zégre, Nicolas P.
Abstract:: This dissertation is a collection of three manuscripts that serve to fill the knowledge gaps and advance methods of detecting the effects of contemporary forest harvesting in experimental catchment studies. While there is a preponderance of studies evaluating the environmental effects of forest harvesting in the western United States, few...
