Dynamic Event Fault Tree Deft

Dynamic Event Fault Tree (DEFT)

The design of systems intended for use in critical applications where failure consequences are high is supported by extensive analysis of potential hazards and their consequences. Probabilistic Risk Assessment (PRA) is a widely used systematic and comprehensive methodology for such analysis, especially in the nuclear industry. PRA identifies and evaluates risks associated with complex technological systems and thus can help improve the system's safety and performance. The use of computer-based systems for a wide variety of applications is continuously increasing. For example, many existing systems for instrumentation and control in nuclear applications are undergoing an upgrade from mechanical or manual to computer-based technology. Computer-based systems are adaptable and flexible, which makes their use desirable; however, this also creates complexities and introduces dependencies in their analysis of failure scenarios and risks. Current PRA techniques, however, are not appropriate for computer-based systems, which makes the PRA of such upgrades and new system difficult.

Safety and Reliability of Complex Engineered Systems

Safety and Reliability of Complex Engineered Systems contains the Proceedings of the 25th European Safety and Reliability Conference, ESREL 2015, held 7-10 September 2015 in Zurich, Switzerland. Including 570 papers on theories and methods in the area of risk, safety and reliability, and their applications to a wide range of industrial, civil and social sectors, this book will be of interest to academics and professionals involved or interested in aspect of risk, safety and reliability in various engineering areas.
