Safety Critical Systems: A Practical Guide

A guide to developing safety critical system processes with detailed information on approaches to current and future safety systems Safety Critical Systems discusses and maps the relationship between various processes of safety critical systems processes, their interdependence, and necessary elements of independence.The book describes the types of systems currently in use, their structures, and their associated creation processes, gathering practical lessons primarily from the field of railway signaling and emphasizing the critical elements that render the requirements, design, analysis, implementation, and management processes robust.The concept of "orthogonal views" is introduced to analyze the processes that surround the creation of a safety critical system and quantify their independence and interdependence.Practical guides for each of the key disciplines involved in system creation are presented, including the oft-neglected management of the overall process.Lastly, possible approa
