This dissertation addresses the "multi-machine carryover sequence
dependent group-scheduling problem with anticipatory setups," which arises in
the printed circuit board (PCB) manufacturing. Typically, in PCB manufacturing
different board types requiring similar components are grouped together to
reduce setup times and increase throughput. The challenge is to determine the
sequence of...
Existing forest site maps have been described as "invaluable
tools" in forest management. Their, economic value potentially materializes
as the summed advantage from better decisions in all phases of
forestry.
Via Bayesian decision analysis, this study establishes optimal
use and economic value of site information for one facet of management...
Lagrangean relaxation is presented as a solution
technique to solve flow constrained area-based harvest
scheduling problems. The best set of multipliers in the
Lagrangean approach is obtained through the subgradient
method. Guidelines to set some parameters to compute the
step size in the subgradient algorithm are provided. An
additional procedure...
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...
