Production systems in the context of Industry 4.0 can react flexibly to changes and failures of components by equipping the system components with some intelligence. Cyber-Physical Systems (CPS) represent a crucial technology of Industry 4.0, characterized by the integration of computation and physical processes. Future production and manufacturing plants should therefore have resilient properties in order to be able to react to faults without human intervention. In this paper, a concept for a resilient production system is discussed using the example of the Fischertechnik Learning Factory 4.0 (FTLF). In the course of this, the incidents occurring in continuous operation are determined in an observation. Based on this observation, the guidelines, strategies, prerequisites, and principles relating to the concept of resilience will be shown and discussed for the resilient architecture. The prerequisites for a resilient architecture include the absence of single points of failure and independence between the sub-components of a system. A resilient production system also requires process disruption management to handle failures with re-configurations based on previously defined possible solutions. A resilient architecture should already be taken into account in the planning and design phase, at which point all incidents that can occur in the system should be known. This fact represents a significant challenge when implementing a resilient architecture in any system.
