Designing safety-critical computer systems

The ubiquitous computer is the electronic component of choice for system developers, who increasingly exploit computing´s power in safety-critical applications such as steer-by-wire automotive systems and powered prosthetics. However, these computer-based systems raise the ongoing concern that they might fail and cause harm. Exploring the systematic design of safety-critical computer systems helps to show how engineers can verify that these designs will be safe. Achieving risk reduction requires dealing with all the system´s components: hardware and software, sensors, effectors, the operator, and the primary source of harmful energy or toxicity: the application.
