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...
The principal objective of this study was to investigate process simulation and
optimization of an existing offshore natural gas process which needed profitability
improvements. Optimization was done using two alternative approaches: a global
approach (response surface methodology) or a local approach (successive quadratic
programming). The global approach was characterized by...
The objective of this research project was to identify the limitations associated
with schedule-based Material Requirements Planning (SBMRP) and to
present a knowledge-based expert system (KBES) approach to solve these problems.
In SBMRP, the basic strategy is to use backward or forward scheduling
based on an arbitrary dispatching rule, such...
This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...

This thesis is intended to provide the management of small to medium sized job shop companies with a written plan to implement a formal computerized manufacturing planning and control system. The research stemmed from a case study performed at a typical job shop where growth of production activities was complicating...
Trials to achieve optimal bucking were made with updated OSU-BUCK software in an eastern and a western Oregon location during the summers of 1993 and 1994. The commercial version of the software allows tagging of each log with bar-code identification numbers and therefore provides tracking from stump to customer. Data...
In northeast China, logging has three stages; timber
harvest, transportation and the operations inside a timber
yard. The timber yard is an intermediate transhipment point between truck transport and rail transport to manufacturing centers. The transhipment capacity of the timber yard is often the limiting acitivity in the logging chain....
