Edge computing-based real-time scheduling for digital twin flexible job shop with variable time window

• A new R-DTFJSS idea was developed to realise high-efficiency production. Edge computing-based framework can enhance the data processing ability. variable time window-based RS strategy used achieve operation allocation. An IHA-based solve method designed reduce computational complexity. Production scheduling is central link between enterprise production and management also key realising efficient, high-quality sustainable However, in real-world manufacturing, frequent occurrence of abnormal disturbance leads deviation scheduling, which affects accuracy reliability execution. The traditional dynamic methods (TDSMs) cannot this problem effectively. This paper presents a real-time digital twin flexible job shop (R-DTFJSS) with edge computing address issue. Firstly, an overall proposed (RS) through interaction physical workshop (PW) virtual (VW). Secondly, implementation process Then, obtain optimal result, improved Hungarian algorithm (IHA) adopted. Finally, case simulation from industrial cooperative described analysed verify effectiveness method. results show that compared TDSMs, effectively deal unexpected disturbances process.
