Using dynamic adaptive systems in safety-critical domains
Ethan T. McGee, John D. McGregor · 2016
The development of safety-critical Cyber-Physical Systems (CPS) is expanding due to the Internet of Things' promise to make high-integrity applications and services part of everyday life. This expansion is seen in the dependencies some connected vehicles have on cloud services that provide guidance and accident avoidance / detection features. Such systems are safety-critical since failure could result in serious injury or death. Due to the severe consequences of failure, fault-tolerance, reliability and dependability should be primary driving qualities in the design and development of these systems. However, the cost of the analysis, evaluation and certification activities needed to ensure that the possibility of failure has been sufficiently mitigated is significantly higher than the cost of developing traditional software.
