Modern Cyber-Physical Systems (CPSs) are composed of numerous components, some of which require real-time management: for example, management of sensors and actuators requires periodic deadlines while processing parts do not. We refer to these systems as partially periodic. In a partially periodic system, precedence constraints may exist between periodic and aperiodic components. It is notably the case in CPSs where sensors measuring physical variables at a fixed sampling rate are typically feeding data to one or more processing part.
