• In this work, the focus is put on the behavior of a system in case a fault occurs that disables the system from executing its applications. Instead of executing a random subset of the applications depending on the fault, an approach is presented that optimizes the systems structure and behavior with respect to a possible graceful degradation. It includes a degradation-aware reliability analysis that guides the optimization of the resource allocation and function distribution, and provides data-structures for an efficient online degradation algorithm. Thus, the proposed methodology covers both, the design phase with a structural optimization and the online phase with a behavioral optimization of the system. A case study shows the effectiveness of the proposed approach.
