Preface
The word “dependability” that appears in the title is not used so often to be familiar with. The word has wider meaning and not only means “reliability” but also includes robustness, safety, security, resilience, and so on. Fault-tolerance technology that equips the redundant subsystems or components in preparation for failure in order to improve “reliability” has been used for many decades. In the meantime, J.C. Laprie expanded the term dependability as a wider concept in 1985 [1] because the meaning of “reliability” that the fault-tolerance technology treated had broadened. After then, dependability and dependable have been used in various fields to this day. Based on such situation and as I also belonged to the committees concerning “dependability,” I dare to use “dependability” in this text, thinking it is one of my vocations to spread the term. As for terms related to reliability, the two terms have been used exclusively in Japanese. The Japanese word shinrai-do means quantitative index of reliability and the word shinrai-sei means qualitative character of reliability. In my personal opinion, the shinrai-sei may fall on the dependability. As written in the title of this book, mitigation of hardware failures, soft errors, and electro-magnetic disturb
