  • 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...

  • 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...

  • 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...

  • Mathematical model for determining the position and line tensions for a tethered logging balloon

    Creator:
    Avery, Robert B.
    Abstract:
    A program was developed on a desktop computer to determine the cable tensions and position of a balloon tethered by two or more guylines. The program was specifically applied to the analysis of the static load lifting capability of the Pendulum Swing Balloon System. This system uses a tethered balloon...

  • Countertrade, a transaction costs approach

    Creator:
    Kelly, Sharon
    Abstract:
    New types of exchange arrangements are becoming increasingly popular for a wide range of goods traded internationally. Several types of countertrade arrangements have been identified, ranging from pure barter to more elaborate schemes where only a portion of the trade is "paid for" in goods, including bilateral trading agreements with...
