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...

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...

Determining labor and equipment costs of logging crews

Creator:: Bushman, Stephen P.
Abstract:: Small, independent logging contractors can benefit from cost control and cost planning. This report details the labor and equipment cost components of a logging crew. Records, both required and available for determining costs, are discussed. Recommended costing procedures are illustrated. Although the study took place in the Pacific Northwest, the...

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...

Log truck scheduling by network programming

Creator:: Shen, Zhenyan
Abstract:: 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....

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...
