  • 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...

  • Group scheduling in electronics manufacturing with integration of internal and external setup times

    Creator:
    Yazdani Sabouni, Mohammad Taghi
    Abstract:
    This research considers a combinatorial optimization scheduling problem in the assembly of printed circuit boards (PCBs) in electronic manufacturing. For the first time in this research, the preparation process, which is typically called kitting operation, is paid attention to and is performed along with the assembly operation, described in this...

  • A multi-product, multi-depot periodic distribution problem

    Creator:
    Parthanadee, Parthana
    Abstract:
    Physical distribution is one of the key functions in logistics systems, involving the flow of products from manufacturing plants or distribution centers through the network of transportation to consumers. The function is very costly, especially for the distribution industries. During the past decades, the significance of physical distribution has increased...

  • Multi-stage group scheduling problems with sequence dependent setups

    Creator:
    Salmasi, Nasser
    Abstract:
    The challenges faced by manufacturing companies have forced them to become more efficient. Cellular manufacturing is a concept that has been accepted as a technique for increasing manufacturing productivity in batch type production by efficient grouping of parts (jobs) with some similarities in processing operations into groups and sequentially matching...

  • Characterization of European hazelnut (Corylus avellana) cultivars using SSR markers

    Creator:
    Gokirmak, Tufan
    Abstract:
    Twenty-one pairs of simple sequence repeat (SSR) primers were used to investigate genetic diversity in 270 accessions of European hazelnut (Corylus avellana) representing a wide geographic range. A capillary electrophoresis system and ABI Genescan® and Genotyper® software were used to determine the allele size generated from each PCR reaction based...
