A dynamic production planning method for a continuous casting plant for casting a strand with a production system which has a predefined production plan, which method includes comparing target production parameters with actual production parameters. If the actual production parameters deviate from the target production parameters, a strand image is created on the basis of actual production parameters. With the aid of the calculated strand image, a check is carried out within the predefined production plan and, if possible, a new production plan is created. If no solution can be found from the predefined production plan, the strand image is transmitted to a production planning system. The production planning system creates a new production plan from all available orders on the basis of a predefined optimization criterion. The new production plan is subsequently transmitted to the production system.

A scheduling method includes a first step where a controller prepares the schedule so that a preliminary processing process and a substrate processing process are performed in that order by a processing unit in common, a second step where, when an abnormality occurs in a substrate processing apparatus in a period from the start of the preliminary processing process to before the start of the substrate processing process, the controller stops the substrate processing process at the processing unit designated in the first step, and a third step where, when the abnormality is resolved, the controller prepares the schedule so that a post-resolution preliminary processing process and the substrate processing process are performed in that order at the processing unit designated in the first step.
