Three strategies for tree bucking at the harvest site: consequences for the sawmill

Creator:: Acker, Timothy A.
Abstract:: The timber shortage in the Pacific Northwest is forcing sawmill owners to improve the competitiveness of their harvesting and processing operations. A computer simulation and financial statement analysis were used to compare the processing efficiency and profitability of three bucking strategies: log cost minimization (traditional 40-foot preferred-length logs); hauling length...

Log cost allocation for multiple mill merchandising systems

Creator:: Leatherman, Louis M.
Abstract:: Co-located mills that share a log resource through a single merchandising facility are challenged with the task of allocating the costs of joint-products in order to determine log cost for each mill during a given period. While allocating joint-costs is inherently arbitrary, some allocation must be made to include raw...

The effect of edging red alder lumber on cut stock production

Creator:: Schott, Kermit A.
Abstract:: It has been observed that edging flitches into lumber unnecessarily reduces the yield of cut stock. This research investigated the yield of cut stock from unedged red alder (Alnus rubra) flitches, and compared it to yields attained from boards subjected to a variety of edging strategies: conventional, light-edging, actual, severe...

The choice of the optimal sawtimber harvesting system (a theoretical approach based on mathematical programming)

Creator:: Mikkonen, Esko
Abstract:: An extension of the sensitivity analysis of linear programming, called parametric programming is used in determining optimal sawtimber logging system mix. The five logging systems under study are manual log-length, system, log-length processor and harvester systems, manual tree-length system and tree-length harvester system. In conditions where it is not exactly...

Determining labor and equipment costs of logging crews

Creator:: Bushman, Stephen P.
Abstract:: Small, independent logging contractors can benefit from cost control and cost planning. This report details the labor and equipment cost components of a logging crew. Records, both required and available for determining costs, are discussed. Recommended costing procedures are illustrated. Although the study took place in the Pacific Northwest, the...

Filling a rough-mill cutting order using a fuzzy logic controller

Creator:: Anderson, James D.
Abstract:: Because of their high cost, reducing the number of boards used to fill an order of dimension parts is an important goal in a lumber rough mill. FLCO (Fuzzy Logic Cutting Order) is a computer program that achieves this goal. Using the concepts of fuzzy logic control, FLCO provides a...

A fuzzy logic controller design and simulation for a sawmill bucking system

Creator:: Delgado, Fidel
Abstract:: This document investigates, justifies, designs, and simulates the application of a fuzzy logic controller/optimizer in a sawmill bucking system application that is the first production station where stems coming from the mountains are processed in a sawmill. One of the areas of success in the application of fuzzy logic is...

Performance analysis of the hardware and software components of an optical scanning system for monitoring lumber sizes

Creator:: Leavengood, Scott A.
Abstract:: In recent years, the forest products industry has been forced to cope with a supply of raw material that is declining in both quality and quantity. In addition, log prices are escalating rapidly. Because log costs may represent as much as 90 percent of the overall production costs of lumber...
