DATE is pleased to present a special hybrid format for its 2022 event, as the situation related to COVID-19 is improving but safety measures and restrictions will remain uncertain for the upcoming months across Europe and worldwide. In transition towards a future post-pandemic event again, DATE 2022 will host a two-day live event in presence in the city of Antwerp (just north of Brussels in Belgium), to bring the community together again, followed by other activities carried out entirely online in the subsequent days. This setup combines the in-presence experience with the opportunities of on-line activities, fostering the networking and social interactions around an interesting program of selected talks and panels on emerging topics to complement the traditional DATE high-quality scientific, technical and educational activities.

  • Session Abstract:  

    An autonomous system is capable of independently achieving a predefined goal in accordance with the demands of the current situation. In safety-critical applications, the operational situations may demand some actions from the system in order to keep risks at an acceptable level. This motivates the implementation of algorithms that estimate, assess and control risks during operation. In particular, the risk assessment at runtime is challenging as it implies moral decision making about acceptability of risks: “How safe is safe enough?”. However, it is also challenging to find a suitable notion of risk. IEC and IEC standards define the term “risk” differently following two “root” definitions: “combination of the probability of occurrence of harm, and the severity of that harm” and “effect of uncertainty on objectives”. The first definition is related to the way how integrity levels like SIL and ASIL are determined at design-time. In the session, we will discuss in how far existing design-time approaches can be adopted to implement an autonomous risk management at runtime. For instance, is it reasonable to implement algorithms that determine integrity levels at runtime?
