Abstract

AbstractSteel-making and continuous/mould casting are the key processes of modern iron and steel enterprises. The continuous and mould casting schedule of mixed whole/half charging plan is the bottleneck for the steel-making and continuous/mould casting process. However, it is very difficult to find a solution against the characteristics and complicated environment. This paper proposed a heuristic batch splitting schedule policy. Based on the complex constraints for this process, we established a model of continuous and mould casting schedule of mixed whole/half charging Plan. The model is solved by heuristic algorithm. Numerical testing supported by Shanghai Bao steel plant demonstrated that the method could realize the production cycle reduction and be more efficient to assist scheduler to make a steel-making and continuous casting scheduling which could realize the high production.
