Shop floor dispatching with variable urgent operations based on Workload Control: An assessment by simulation

Abstract Meeting customer time requirements poses a major challenge in the context of high‐variety make‐to‐order companies. Companies need to reduce lead and process urgent jobs time, while realising high delivery reliability. The key decision stages within Workload Control (WLC) are order release shop floor dispatching. To best our knowledge, recent research has mainly focused on stage inadvertently ignored dispatching stage. Meanwhile, urgency job is not only related its due date, but also affected by dynamics floor. Specifically, may decrease at downstream operations job's routing, since priority for accelerates production speed upstream operations. And occupying resources increases waiting non‐urgent workstation. This phenomenon leads change jobs. Misjudgement therefore result actual being processed time. In response, authors focus consider transient status WLC. rejudged input buffer each workstation, which firstly defined as Using simulation, results show that considering contributes speeding up meeting performance both General Flow Shop Pure Job Shop. addition, percentage tardy greatly norm levels, especially severe level.
