This paper deals with a two stage processing production system. During a production period, the first processing operation (pressing & cutting) is optimized by using the selected cutting pattern and the second (evening) is controlled by a suggested heuristic sequencing method which groups the strips into batches to minimize the total flow time. The selection of the appropriate production period gives us the possibility to integrate the above systems into one optimization model.
