Abstract :
In this paper an alternative set-up generation system is developed for a tandem cold mill to be used during emergency operation in case of shut-down of the main operating mode. The system is based on a cost function that evaluates the mill quality and productivity for each set-up. This cost function is minimized using the Nelder and Mead simplex method. Despite to be simpler than the main set-up generation system, it is faster, more accurate and safer than the usual emergency mode, which is based on a set of tables.
