  • 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...

  • 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...

  • Component to multi-track feeder assignment and board sequencing for printed circuit board assembly

    Creator:
    Li, Yu-An
    Abstract:
    This research was motivated by the use of multi-track feeders in the printed circuit board (PCB) assembly. In a low volume, high mix production environment, setup time is usually considered more important than processing time. Implementation of multi-track feeders not only increases the capacity of the surface mount machines but...

  • An analysis of risk management strategies for southern Alberta feedlots

    Creator:
    Freeze, Brian S.
    Abstract:
    Feedlot finishing of beef cattle in Southern Alberta involves income risk due to the variability of prices of feeders, feed and finished cattle. Several strategies are available to reduce this risk, including hedging of cattle on feed, participation in a Federal- Provincial government and producer established income stabilization program for...
