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...

Group-scheduling problems in electronics manufacturing

Creator:: Geloğullari, Cumhur Alper
Abstract:: 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...

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...

Hybrid flowshop scheduling with dual resources in a supply chain

Creator:: Mehravaran, Yasaman
Abstract:: This dissertation addresses a hybrid-flow shop scheduling problem with dual resource constraints in a supply chain. Most of the traditional scheduling problems deal with machine as the only resource. However, other resources such as labor is not only required for processing jobs but are often constrained. Considering the second resource...

Schedule-based material requirements planning : an artificial intelligence approach

Creator:: Kim, Sunuk
Abstract:: 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...
