A model for the determination of optimum setting dimensions for tractor yard/swing operations

Creator:: Nickerson, Devon B.
Abstract:: A problem of interest to forest managers is the optimum arrangement of truck roads and landings for economical logging operations. This problem becomes more complex if,a combined yarding and swinging operation is considered. I,t is possible to formulate a mathematical model to express the cost per unit volume for a...

Linking a growth model with logging production costing

Creator:: Bergan, Ernest E.
Abstract:: A model (called MERLIN) is presented that can allow the resource manager to consider the combined effects of silvicultural treatments and their effect on expected logging production and costs. This integrated analysis takes place within the framework of personal computer software readily available to most managers. This integration is accomplished...

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...

LOGCOST a harvest cost model for southwestern Idaho

Creator:: Giles, Robert Steven
Abstract:: LOCCOST is an interactive computer program that predicts stump to mill logging costs, stumpage and net present value of a harvest based on stand data, pond value and logging parameters, entered by the user. The program is intended for use by foresters to evaluate the economics of different stand management...

A simulation of the comparative costs and benefits of skyline strip thinning

Creator:: LeDoux, Chris B.
Abstract:: Strip thinning is recognized as a way of commercial thinning young-growth stands. strip thinning has been used worldwide. The purpose of this study was to explicitly evaluate the costs and benefits associated with skyline strip thinning in young Douglas-fir (Pseudotuqo menzesii Franco) stands in the Pacific Northwest and to compare...

Modeling biomass transport on single lane forest roads and monitoring GPS accuracy for vehicle tracking under different forest canopy conditions

Creator:: Simwanda, Matamyo
Abstract:: The transportation of wood and biomass resources from landing and other collection locations to processing and distribution sites is a substantial cost within the wood supply chain. These high costs provide a basis for research aimed at improving biomass transportation planning decisions and potentially reducing biomass transportation costs. Chip vans...

A method of selection of cable harvesting machines for Vermont

Creator:: Stirler, Dennis John
Abstract:: There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method. The method chosen for this paper is made up...

A simulation of the operation of a log landing for a heli-stat airship in old-growth timber

Creator:: Gerstkemper, John C.
Abstract:: This paper discusses the development of a computer simulation program for the operation of a log landing for the proposed Helistat airship. The first part of the paper describes the time study used to develop production rates for the chasers, buckers, front-end loaders, and skidders to be used on the...

Simulation of mechanized log harvesting systems

Creator:: Wiese, Christoph
Abstract:: The focus of this research is to develop a personal computer based simulation model of the mechanized logging process, from felling until the log arrives at the sawmill. The SLAM II simulation language is used for modeling, and the main emphasis is on the overall performance of this system, and...

Skyline thinning production rate equations using the thin simulation model

Creator:: Starnes, Lawson W.
Abstract:: This paper shows how ten easy-to-use linear skyline thinning production rate equations were obtained by transforming existing but more cumbersome turn time equations using the THIN simulation model [11). The equations provide reasonable approximations of delay-free hourly production for several cable yarders operating skyline thinnings under a variety of conditions....
