Purpose and goal
The academic party (Linköping University) has gain valuable insights in the complex planning situation at SSAB. An overview of their order-driven production planning problems has resulted in several sub-problems suitable for mathematical modelling and optimization techniques.
Results and expected effects
In accordance with the stated expectations, several self-contained sub-problems have been identified. For one of them, the daily planning problem for the continuous caster in Luleå, we have developed and implemented an optimization model, with promising results. The findings throughout the project have been collected in a technical report, which contains mathematical optimization models, implementation details and discussions (restrictions/shortcomings of the models). This report is an excellent basis for a planned journal publication.
Approach and implementation
The proposed working plan and organization for the project has been successful. After the initial literature study, the involved parties have had continuous correspondence and regular video call meetings 1-2 times each month. Further, the academic party (Nils-Hassan) has visited SSAB:s facilities in Borlänge and Luleå to conduct physical meetings and to get a better understanding of the working environment. Both parties are interested in a continuation of the project, and discussions are in progress on how to realize future cooperation.
