Improved timber harvesting through better planning: a GASP IV simulation analysis.
ABSTRACT INCREASING constraints placed on timber harvesting operators demand the use of sound planning. To demonstrate the usefulness of computer simulation as a planning tool a GASP IV simulation model—SAPLOS (Simulation APlied to LOgging Systems)—was used to examine the operational phases of three logging systems on the steep slopes of the U.S. Appalachian hardwood region. Through use of this tool, the logging manager can evaluate alternate harvesting systems before field work begins and thus prevent costly work delays.
