Modelling manufacturing systems for control: a validation study

This contribution deals with the modelling of manufacturing systems forcontrol. First the concept of effective process times is introduced as ameans to arrive at relatively simple discrete event models ofmanufacturing systems based on measured data. Secondly, a controlframework is presented. Thirdly, a validation study is presented whichshows that the currently available PDE-models for describing manufacturingsystems need further improvement. Finally some criteria are specified which a PDE-model should at least meet in order to be considered valid
