A concept of production scenario for the steelmaking-continuous casting production process and the mathe-matical description of such concept were proposed.The production scenario was described with the varia-tion of the equipment status and the production material properties based on the executing production schedule.Then, the dynamic characteristics of the production process could be described with the evolu-tion process of production scenario.Through analyzing the influence of the dynamic production scenario on production scheduling, three key points about the scheduling problems were identified: the problem for integrating the schedules of different batches that is non-neglected when making a schedule, the problem for matching the material flow with the schedule that should be solved when implementing a schedule, and the problem for eliminating the deviations between the initial schedule and implemented schedule that should be solved when rescheduling in a disturbed environment.Finally, a set of experiments were con-ducted, and the results demonstrated that making the production schedule and solving the rescheduling problem for steelmaking-continuous casting process with addressing the above three problems improve the adaptability of the schedule in dynamic environment.
