Abstract (English)

Automation of logistics in the hot slab yard of voestalpine Stahl GmbH is a difficult task in an interconnected environment where differently sized slabs with a wide range of follow-up destinations create a complex set of stacking rules. The limited space and the requirement for efficiently using transport equipment (cranes, trailers, and vehicles) further complicate matters. In this work the author will present an optimization model that is applied to the hot slab yard at voestalpine Stahl GmbH. In order to do so the real world problem is broken down into two sub-problems based on the decision making process. Results of the model are compared with expert knowledge, past data and a pilot is implemented in a part of the hot slab yard. To conclude the work a summary of the problems (implicit knowledge and a missing link between research and implementation) during the implementation process and an outlook of the next steps of the project is given.
