A review of the principles of the safety of software-based
equipment, this book begins by presenting the definition principles
of safety objectives. It then moves on to show how it is possible
to define a safety architecture (including redundancy,
diversification, error-detection techniques) on the basis of safety
objectives and how to identify objectives related to software
programs. From software objectives, the authors present the
different safety techniques (fault detection, redundancy and
quality control). ‘Certifiable system’ aspects are
taken into account throughout the book.
Contents
1. Safety Management.
2. From System to Software.
3. Certifiable Systems.
4. Risk and Safety Levels.
5. Principles of Hardware Safety.
6. Principles of Software Safety.
7. Certification.
About the Authors
Jean-Louis Boulanger is currently an Independent Safety Assessor
(ISA) in the railway domain focusing on software elements. He is a
specialist in the software engineering domain (requirement
engineering, semi-formal and formal method, proof and
model-checking). He also works as an expert for the French notified
body CERTIFER in the field of certification of safety critical
railway applications based on software (ERTMS, SCADA, automatic
subway, etc.). His research interests include requirements,
software verification and validation, traceability and RAMS with a
special focus on SAFETY.
