AbstractThe course introduces to linear and non-linear modelling of processes via "Design of Experiments". DOE is an actively generated regression analysis for fast and economic determination of input parameters to achieve an optimal output with a reduced number of experiments.
ObjectiveThe students gain insight into theory and practice of DOE. They learn the most important terms, DOE types, full and fractional-factorial modelling and what has to be respected during the factor selection and investigational procedure, everything enriched by a practical exercise. The course provides indispensable basic knowledge for target-oriented scientific experimentation.

The complete processing chain, from sensing to action, sensors, signalization, control and closed loop control, power electronics and actors is discussed.

Basic elements, sensors and actors, transmitting from mechanics to electronics and vice versa, as well as control systems and interfaces and bus systems are presented. In production technology these are applied in the different automation devices and then condensed to full production lines.

Different concepts for automation, layout planning, description and simulation and the interface to and safety of humans are topics. The economic boundary conditions are taken into account and lead to concepts for availability and reliability of complex systems and to the discussion of today's research concepts for fault tolerancing systems, to autodiagnosis and self repair, cognitive systems and agent systems.
