Production rates of skyline, balloon, and helicopter yarding systems from gross time study analysis

Creator:: Curtis, Richard James
Abstract:: 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...

Full Text:: variables shown statistically to influence yarding production rates for all logging systems studied were

A methodology for real-time scheduling of jobs with splitting on unrelated parallel machines

Creator:: Subur, Fenny
Abstract:: Unrelated parallel machines are machines that perform the same function but have different capacity or capability. Thus, the processing time of each job would be different on machines of different types. The scheduling environment considered is dynamic in both job release time and machine availability. Additionally, each job considered can...

An approximation procedure for the allocation of inspection effort

Creator:: Turnblom, John Warren
Abstract:: A comparison of two procedures which allocate inspection effort within a production sequence is presented here. The concern for quality and the need to hold down the costs of quality has resulted in mathematical models which locate inspection so that the desired quality is attained at a minimum cost. In...

Planning and implementing a manufacturing control system in a job shop environment

Creator:: Maplestone, Robert N.
Abstract:: 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...

Heuristic algorithm for multistage scheduling in food processing industry

Creator:: Juwono, Cynthia P.
Abstract:: A multistage production system consists of a number of production stages that are interrelated, that is the output from one stage forms input to the next stage. There are constraints associated with each stage as well as constraints imposed by the overall system. Besides, there are multiple objectives that need...

A Unit Manufacturing Process Characterization Methodology and Supporting Terminology for Sustainable Manufacturing Assessment

Creator:: Garretson, Ian C.
Abstract:: Manufacturing industry drives economic activity and growth around the world, but manufacturing activities consume large amounts of material, energy, and labor resources. Therefore, the impacts of manufacturing need to be accounted for and reduced. Direct benefits of manufacturing are products and income, which, in turn, influence the lives of people...

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...

Simulation and optimization of an offshore natural gas process

Creator:: Chaiwanakupt, Nopasit
Abstract:: 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...

A linear test bed for characterizing the performance of ocean wave energy converters

Creator:: Hogan, Peter M.
Abstract:: Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...
