  • 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...

  • 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...

  • 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...

  • Implementing quick response (QR): successes and challenges

    Creator:
    Lee, Duck Weon
    Abstract:
    Quick Response is an umbrella term for strategies to cut lead times and to eliminate unnecessary production costs from a manufacturing plant to a consumer market. In particular, the textile and apparel industries need strategies to quickly respond to a changeable market in the international supply chain. As the industry...

  • A novel control design for a wave energy converter

    Creator:
    Schacher, Alphonse A.
    Abstract:
    Ocean wave energy is rapidly becoming a field of great interest in the world of renewable energy. Significant advancements in design and technology are being made to make wave energy a viable alternative for our growing energy demands. The two major hurdles for ocean wave energy to make a significant...
