  • The development of productivity interfirm comparison procedures for the cement industry of Saudi Arabia

    Creator:
    Al-Agha, Osama K.
    Abstract:
    Productivity Interfirm Comparison (PIC) is a simple method used to improve productivity at the firm level, where a number of firms operate in the same product line so that performance information on the firms can be compiled and compared. This results in identifying potential areas for improvement or exploitation. The...

  • Design and implementation of a heuristic-based decision support system for nurse scheduling

    Creator:
    Sitompul, Darwin
    Abstract:
    A decision support system (DSS) for nurse scheduling in hospitals is developed and implemented on microcomputer. The system includes algorithms and databases for developing weekly work and shift patterns and combining these into working schedules for nurses for a specified time horizon, and interface modules for the user to interact...

  • Measuring costs of sequestering carbon in forest stands with different management regimes in western Oregon

    Creator:
    Zyrina, Olga A.
    Abstract:
    This project was a part of larger work that compared major factors controlling patterns of carbon dynamics in two regions of the globe, the Pacific Northwest, USA and northwestern Russia. It was funded through the NASA foundation (grant # NAG5- 6242). Human economic activity is causing the release of pollutants...

  • A comparison of the value of forest plans developed under three levels of detail regarding management intentions

    Creator:
    Hirte, Sarah Rebecca
    Abstract:
    In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...

  • Aerial forest operations : mineral amendment project

    Creator:
    Cornell, Jennie L.
    Abstract:
    A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

  • Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

    Creator:
    Acuna, Mauricio A.
    Abstract:
    There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

  • An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

    Creator:
    Helvoigt, Ted L.
    Abstract:
    The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

  • The economics of carbon sequestration in western Oregon forests

    Creator:
    Im, Eun Ho
    Abstract:
    This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

  • Evaluation of a prototype NIR system for Douglas-fir wood density estimation

    Creator:
    Belart Lengerich, Maria Francisca
    Abstract:
    Forest products companies in the U.S. face vigorous competition from other wood producers around the world and other industries (steel, aluminum, plastics, composites). To be competitive, forest companies need to control costs, sort and allocate logs to the most appropriate markets, and recover more value at time of harvest. Interest...

  • In-forest log segregation based on acoustic measurement of wood stiffness

    Creator:
    Amishev, Dzhamal Y.
    Abstract:
    To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...
