In turbulent and innovative markets it is important for any production enterprise to have a high level of robustness within a specific range of output quantities vis-à-vis any changes it will be affected by. In fact, it is necessary to provide a planning routine for the adaptability of production systems as early as during the planning stage. In this way it will be able to respond to unforeseeable developments. Due to the demographic development in particular, it is no longer appropriate to consider the staff structure after the configuration of the machinery equipment has been planned. It is much more important to design manufacturing systems to be productive during the whole usage phase of the production system without a change of the permanent staff. The aim is to enhance the planning task in such a way that the production system can be adapted technically and organisationally as well as in a personnel-oriented manner to a changing performance of an ageing workforce.
