DFG-Research Training Group 1491: Ramp-up Management

Duration: 2014 – 2017

Funding: Deutsche Forschungsgemeinschaft (German Research Foundation) (DFG)


The research focus is to explain the ramp-up and develop models and methods for reducing instability in the ramp-up phase. Production ramp-up is the period between completion of the development process (including product approval) and full capacity utilization.

The problem of complexity in the decision making process cannot be adequately solved through a centralized approach: in an inductive and decentralized process, decisions on the various sub-processes are to be optimized while systems interdependencies are taken into account. In this way, the ramp-up process can be monitored, improved and led to success. It is a goal of the research school to train young researchers in dealing with complex decision-making situations during production ramp-up. Our graduate students shall be provided with a better understanding of the basic processes which makes it possible for them to develop solution strategies in both academic and industrial contexts.

A decision model will be developed which takes into account the systems behavior of the ramp-up process in relation to all factors essential to decision making. In addition, a set of criteria will be developed which will systematically help in making single decisions which are part of the overall process. The decision model will allow managers to anticipate problems in the ramp-up process on a meta-level and enable them to proactively develop solution strategies.
