This session presents novel methodologies for the design and analysis of safety critical real-time systems. The first paper concerns sensitivity analysis, which characterizes bounds on admissible system parameters. The contribution concerns the bounds on admissible activation pattern of the recurrent real-time tasks. The last two papers concern mixed-criticality scheduling, an effective approach to address diverse certification requirements of safety-critical systems that integrate multiple subsystems with different levels of criticality. The contribution of the first one includes schedulability analysis algorithms to enable integration of preemption threshold (technique which controls the degree of preemption) in order to reduce scheduler overhead and improve system predictability. The second one proposes an Early-Release EDF scheduling algorithm, which can judiciously manage the early release of low-criticality tasks without affecting the timeliness of high-criticality tasks.
