Predicting running skyline performance based on the mechanical capability of the yarder

Creator:: Wilbanks, Samuel James
Abstract:: The objective of this paper is to develop a methodology for determining running skyline yarder performance based on the mechanical characteristics of the yarder and its interaction with the load and the terrain. A code for implementing this procedure on the HP-9020 will be prepared .

An optimization model to allocate forestry incentives funds in teak plantations of the southern-coastal region of Guatemala

Creator:: Pavez, Ricardo
Abstract:: Guatemala is internationally recognized as a country suitable to invest in the forestry industry. The first Guatemalan Forest Incentive Program – PINFOR- was implemented in 1996 to foster local forestry through cost-sharing. However, it lacks both formal land use planning processes and mechanisms to assess economic potential of projects, so...

SkidPC 2000: a mobility, production, and rut depth simulation program

Creator:: Spong, Ben D.
Abstract:: 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...

Rigid link and catenary skyline analysis programs for microcomputers

Creator:: Kendrick, David E.
Abstract:: 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...

Setting forest road maintenance and upgrade priorities based on environmental effects and expert judgment

Creator:: Coulter, Elizabeth Dodson
Abstract:: The prioritization of road maintenance projects is an important forest engineering task subject to limited budgets and competing investment needs. Large investments are made each year to maintain and upgrade forest road networks to meet economic and environmental goals. Many models and guidelines are available for single-criterion analysis of forest...

Estimating machine rates and production for selected forest harvesting machines operating in the western United States and determining the most economical machine combinations under representative conditions in Turkey

Creator:: Akay, Abdullah Emin
Abstract:: During the last decades, there has been increasing interest in ground-based mechanized harvesting systems in the western United States as harvest of second growth increased. A major reason for that interest is that labor productivity using conventional methods decreases with smaller tree size. In Turkey, the application of mechanization is...

Determination of optimum setting dimensions and road standards for uniform terrain

Creator:: Yeap, Yun Huat
Abstract:: The calculation of optimum setting dimensions and road standards simultaneously on a timber sale is a common problem in uniform terrain. Analysis usually begins by evaluating certain road standards under various road spacings and profile geometries. Linear costs, single period entry and simplified skidding patterns are often assumed to permit...

Tactical forest planning using the scheduling and network analysis program (SNAP II)

Creator:: Mafera, Thomas E.
Abstract:: 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...

Minimizing total cost of construction, maintenance, and transportation costs with computer-aided forest road design

Creator:: Akay, Abdullah Emin
Abstract:: The systems currently available for forest road design are not capable of making computer-aided design judgments such as: 1) automated generation of alternative grade lines, 2) optimizing vertical alignment, 3) minimizing total cost of construction, maintenance, and transportation costs, and 4) aiming for least environmental impacts. In recent years, advances...

Timber transportation optimization and vehicle routing: a GIS application in South Africa

Creator:: Oberholzer, S. Francois
Abstract:: 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...
