This paper deals with the Steelmaking and Casting phases of a real integrated plant. We focus on the scheduling of the casts on the machines of the process and on the cranes that perform the internal transport. The casting phase is made by Continuous Casting and Ingot Casting machines. A Mixed Integer Linear Programming model is presented for the schedule of operations, with the objective of minimizing the makespan. The model is divided into four sub-models: the steelmaking and casting processes, the cranes, the continuous casting machines and the ingot casting machines. An example is presented to show the application of the proposed model.

Abstract

This paper deals with the Steelmaking and Casting phases of a real integrated plant. We focus on the scheduling of the casts on the machines of the process and on the cranes that perform the internal transport. The casting phase is made by Continuous Casting and Ingot Casting machines. A Mixed Integer Linear Programming model is presented for the schedule of operations, with the objective of minimizing the makespan. The model is divided into four sub-models: the steelmaking and casting processes, the cranes, the continuous casting machines and the ingot casting machines. An example is presented to show the application of the proposed model.
