Online Probabilistic Risk Assessment of Complex Marine Systems. Principles, Modelling and Applications/Вероятностная онлайн-оценка рисков сложных морских систем. Принципы, моделирование и приложения

Издание на английском языке
This book provides a general framework for online risk assessment considering human, software, and hardware interactions in automated and autonomous complex systems, with particular focus on marine applications. There is a significant interest in industry, authorities, and academia on the prospects of complex autonomous systems. Much work focuses on technological developments and discussions on economic, legal, and safety implications. There has been less focus so far on risk assessment and modeling concerning the conceptualization, design, and, in particular on the safe operation of these systems.
