ABSTRACT: Industry 4.0 and Cyber Physical
Production Systems (CPPS) are often discussed and partially already sold. One important
feature of CPPS is fault tolerance and as a consequence self-configuration and restart
to increase Overall Equipment Effectiveness. To understand this challenge at first
the state of the art of fault handling in industrial automated production systems
(aPS) is discussed as a result of a case study analysis in eight companies developing
aPS. In the next step, metrics to evaluate the concept of self-configuration and
restart for aPS focusing on real-time capabilities, fault coverage and effort to
increase fault coverage are proposed. Finally, two different lab size case studies
prove the applicability of the concepts of self-configuration, restart and the proposed
metrics.
