The Safety-Critical Systems Symposium is now established as the major UK conference on safety-critical systems. This volume of proceedings contains a broad range of relevant and up-to-date topics, offering information not only to industry on new technologies, but also to academia on industrial techniques such as risk assessment and safety analysis. The book covers subjects from collaborative projects and strategic views through to new technologies from the fields of neural networking, artificial intelligence, formal methods and robotics. Also covered are the use of languages in safety-critical software development security principles, verification and validation, and coverage of new developments in risk analysis, hazard identification and assessment.
