Selected Challenges of Software Evolution for Automated Production Systems Birgit Vogel-Heuser, Stefan Feldmann, Jens Folmer, Matthias Kowal, Ina Schaefer, Jan Ladiges, Alexander Fay, Christopher Haubeck, Winfried Lamersdorf, Sascha Lity, Timo Kehrer, Matthias Tichy, Sinem Getir, Mattias Ulbrich, Vladimir Klebanov, and Bernhard Beckert Automated machines and plants are operated for some decades and undergo an everlasting evolution during this time. In this paper, we present three related open evolution challenges focusing on software evolution in the domain of automated production systems, i.e. evolution and co-evolution of (interdisciplinary) engineering models and code, quality assurance as well as variant and version management during evolution.
