Creator:: Moss, J. Alexander
Abstract:: The focus of this research concentrates on enhancement of the LOGSIM mechanized log harvesting system simulator. Enhancement of software focuses on overall improvement of the user environment as well as improvement of the performance and capabilities of the simulation package. An enhanced version of the front-end interface program is developed...

Creator:: Aedo-Ortiz, Dario M.
Abstract:: This study concerns the use of a discrete-event simulation model for analyzing the production of a mechanized forest harvest system. The simulation models a field collection data set of a harvester-forwarder system which was previously collected by the Forest Engineering Department of Oregon State University. The computer software consisted of...

Creator:: Scott, Thomas M. (Thomas Matthew), 1958-
Abstract:: The potential gains that could be realized from optimizing timber harvesting are significant. To a great extent it is these initial functions that dictate the quality of future manufacturing steps. Timber harvesting systems are defined by the operations they contain and the equipment that perform them. For any given harvesting...

Creator:: Durston, Thomas A.
Abstract:: Multispan skyline logging systems are cable systems designed to yard logs over steep terrain having a constant or convex slope. An intermediate skyline support is used to raise the skyline high enough to achieve ground clearance without overstressing the skyline. Certain improvements in performance can be realized by providing intermediate...

Full Text:: published user-friendly computer programs capable of analyzing a variety of typical skyline logging

Creator:: Eldred, Peter D.
Abstract:: The planning of harvests and management activities for forested lands has traditionally been done with either binary search or linear programming. Since both these techniques have some advantages over the other, they have remained in wide use. Hoganson and Rose (1984) have suggested a technique that theoretically could overcome some...

Creator:: Nelson, John Douglas
Abstract:: Procedures are developed for integrating short-term, area-based plans with long-term, strata-based harvest schedules. These procedures were tested on a 4000 hectare tract of forest land in British Columbia. It is shown that a combination of these two approaches to forest planning provides a spatially feasible short-term solution that is also...

Creator:: Campbell, Thomas M.
Abstract:: Time studies of logging equipment are important to determine production rates, calculate logging costs and locate operating inefficiencies. However, using present time study techniques, they are also costly and time consuming to complete. This project will develop a new data gathering and storage technique using the HP-75 portable computer to...
Resource Type:: Capstone Project

Creator:: Calkin, David E.
Abstract:: An integrated model combining a wildlife population simulation model, and timber harvest and growth models was developed to explore the tradeoffs between the likelihood of persistence of a wildlife species and timber harvest values on a landscape in the Central Oregon Cascades. Simulated annealing, a heuristic optimization technique, was used...
