  • A new dispatching mechanism for parallel-machine scheduling with different efficiencies and sequence-dependent setup times 

    Wu, Gen-Han; Pourhejazy, Pourya; Li, Wang-Xian; Wu, Tai-Hsi (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-22)
    he Apparent Tardiness Cost (ATC) dispatching rule was initially developed to minimize tardiness in single machine scheduling problems. ATC extensions have been frequently applied in other production settings, relying heavily on blocking idle machine capacity with a single-machine outlook; this approach may not result in the best outcomes, considering that machines have different efficiencies. This ...
