Information is one of the key enabler for transformability of factories. As factories have to be able to adapt their processes very fast
according to the changing environment, the approach introduced here aims at supporting production process planning and
optimization. The performed activities are guided by configuration concepts and methodologies. First the great potential of
employing knowledge-based systems in production process planning is emphasized. Afterwards the questions will be answered,
what knowledge is relevant, how this knowledge is modeled and how it is used for the configuration of production processes. The
contribution closes with a roadmap of future activities.
