Continuous casting and hot strip milling are two successive production steps in the steel industry. In her thesis Imke Mattik develops model formulations to integrate the scheduling of continuous casters and hot strip mills. Aim is to reduce the waiting times of the pre-products, called slabs, between the production steps and at the same time to reduce the energy consumption. Along with two different model formulations extensive numerical tests and comparative analyses are provided.
