In today’s cyber physical systems, adaptability concepts can be used to fulfill fail-operational requirements while enabling optimized resource utilization. However, the applicability of such concepts highly depends on the support for the engineering during system development. We propose an approach to cope with the challenges of fail-operational behavior of CPS in which engineers are supported by design concepts for realizing safety, reliability, and adaptability requirements through the use of architectural patterns. The approach allows expressing concepts for fail-operational behavior at the software architecture level. By our approach, the effort for developing adaptive CPS can be kept low by utilizing fail-operational architectural patterns for general and reoccurring safety-relevant mechanisms. This is demonstrated by an application to an automotive case system.
