Integrated Scheduling System on Steel-Making and Continuous Casting with Application

Abstract The integrated scheduling problem of steel-making and continuous casting is discussed. To solve the problem we develop a scheduling system with the architecture of three tiers. Its main functions include: schedule making and adjusting, matching and optimization, abnormal logistics handling and production information management. A hybrid heuristic and optimization algorithm is developed for the solution. The scheduling system had been embedded into the whole MES of a big iron and steel group in China. This approach had been applied to a branch plant of stainless steel. The satisfactory results have been achieved.
