- This paper presents a successful off-lineoptimisation case study of a sheet-metal press line for theautomotive industry. The proposed off-line optimisationmethod results not only in increased production rate but also inobtaining smoother material handling motions. The off-lineoptimisation method contains two parts. The first part is aparameter study, combining factorial design with productionline simulation including emulated control systems andresulting in a simplified performance model based on multiplelinear regression. The second part is an optimisation on thesimplified performance model using the Nelder Mead simplexmethod aiming at production optimisation. Due to thecomplexity in a modern production line, it is not possible tocreate a useful model representation of the entire controlsystem code/function. Therefore, the proposed optimisationmethod is based on using production line simulation includingemulated control systems with the real IEC 61131-3 controlcode. Our approach in this work is a parameter variationstrategy for optimisation, i.e. adjusting the control systemparameters in the same way as the line operators do, and notchanging any control strategy.
