Abstract The dynamic scheduling of steel processes is very important for continuous, dynamic and orderly operation of the whole steel processes. The current situation of dynamic scheduling for steel processes were summarized. Aiming at the three difficulties of object description, optimization solution and change adaptation, the corresponding solutions were put forward, that is, multi-agent modeling and digital simulation technology, iterative optimization method combining rules and optimization algorithm, and uncertain optimization scheme in different scenarios. A dynamic scheduling platform of steel processes based on deep cyber-physical fusion was constructed. The operation process of dynamic scheduling based on the platform was introduced. The deep cyber-physical fusion method and technology of dynamic scheduling were discussed from three aspects of collaborative rules, process simulation and dynamic Gantt chart. This technology can improve the multi-objective global optimization level of the dynamic scheduling system for steel processes and enhance its adaptability to complex working conditions.
