The study of highlead logging operations through the use of
statistical models is investigated, and their potential use for estimating
and control of operations examined.
During the preliminary phases of the study 16 work elements
and 26 influencing variables are identified and measurement criteria
developed for each. A coding system...
To abstract the fundamental market structures of stumpage sold from the Siuslaw National Forest, a three-equation structural model with different assumptions on private cut was empirically derived. Under the private cut price-fixed assumption, the structural model can be simplified as a single-equation model with stumpage price as dependent variable and...
A dynamic programming algorithm (MS PATH) was used to develop a stand level optimization model, FPS Optimizer. The model incorporates a late-seral constraint on the profit maximizing objective function utilizing a four-descriptor structural index as a proxy. This index, the 'Old-Growth Index', rates the late-seral structural quality of a given...
Competitive bid sales of U.S. Forest Service in the Pacific Northwest
timber resources have significant effects on the economies of
Oregon, Washington, and Idaho. These sales contribute to the economic
vitality of small regions or communities dependent upon timber as a primary
resource input. Any changes in the price or...
The number of sawmills in the coastal lumber-producing area
of British Columbia diminished from 364 In 1955 to 162 in 1968. In
the interior of the province the reduction in plant numbers was from
2125 to 740. Over the same period lumber production in the province
increased from 4.9 billion...
Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...
