An economic analysis and optimization of forest biomass processing and transportation at the operational level is presented. Renewable sources of energy have captured the interest of public and private institutions to develop cost-effective supply chains to reduce dependence on fossil fuels. The production of energy from forest harvest residues constitutes...

An economic analysis and optimization of forest biomass processing
The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...
Two manuscripts are presented, each examining the potential impacts of emerging technologies on the economic feasibility of fuels reduction treatments on federal forest lands. Both manuscripts were prepared as part of the larger effort funded by the Institute for Working Forest Landscapes under the “Opportunities for biochar production to reduce...
A computer program package to estimate cable yarding
payload capability was made. The package was intended to
expand applicability of existing packages and to be user
friendly. It has six system options: live skyline, standing
skyline, running skyline, slackline, multispan and highlead.
In the standing skyline and multispan analyses, load...
Skyline logging is a commonly used method of harvesting
logs, particularly on steep slopes. Logging systems
planners frequently solve two kinds of skyline analysis
problems. The first is the maximum payload problem and the
second is the standing skyline load path problem. Computer
assisted skyline analysis techniques have been available...
Approximately 750 million acres, or one-third, of the total area in the United States is in forest land. The United States Forest Service, a 34,000 person agency of the Department of Agriculture, is responsible for the management of roughly 20 percent of the forest land in the United States. The...
Large woody debris recruitment to streams from adjacent riparian forests influences stream
channel morphology, sediment routing, and fish habitat. A mathematical model was developed
to 1) determine whether the trees in a stand adjacent to a stream, upon falling, would provide
large woody debris of a specified size to the...
In Pakistan, forest land is either owned by government or at least managed by provincial forest service if it is private land. Timber is logged by contractors and delivered by small four wheel drive trucks over low standard roads to a transfer yard, where it is unloaded to await transport...
SkidPC 2000, written in Visual Basic Version 6.0, is an updated version of the 1987 DOS program that calculates the mobility and productivity of ground-based logging vehicles over a ground profile. As in the original program, the user enters the vehicle and operational conditions and the program will calculate the...
Evaluating different timber transport configurations for a large road network is a challenging
task. Road curves are often too sharp to allow access to certain configurations. This paper
evaluates the feasibility of using a geographical information system (GIS) road data set as a basis
for determining the accessibility of plantation...
