A Steelmaking-Continuous Casting Production Scheduling Model and Its Heuristic Algorithm

Under the technical constraints of Steelmaking-Continuous Casting production, a MILP model is established which considers both assignment of heats and scheduling for the production environment with multiple machines in stages. Based on the research of assignment rules and relaxation of machine conflicts, a heuristic algorithm is given to solve the model. The example shows that the algorithm is effective.
