The strict requirements of the production process defeated most of the earlier approaches to steel makingcontinuous casting production scheduling, mainly due to the lack of information in the optimization models. Our formulation of the problem is based on the alternative graph, an.The alternative graph formulation allo. oon and Hrymak,1999, Harjunkoski and Grossmann,2001 and Tang et al,2002. In this paper of scheduling the production of stainless steel ingots in a production line located in central Italy.The plant produces a large variety of ingots,to be used in a ical position,or ―grade‖.The ingot formation process,or steelmaking continuous casting process, has extremely strict requirements of material continuity and floe to fulfill in order to achieve suitable properties on the final product,thus making the production scheduling problem particularly challenging.Show the layout of the production line.

The production scheduling problem consists of determining the scheduling of operations to be performed on molten steel at the different production stages from steelmaking to continuous casting.
