Abstract
People Usually Speak of dependability as a whole and generally agree that more of it is a good thing. During the IEEE P982 working group’s research and discussions, we were intrigued by the idea of characterizing dependability as a single-number score derived from its constituent measurements (reliability, availability, supportability, and recoverability.) A dependability score could provide quantitative answers to significant questions such as: Has it changed over successive system versions? To what extent is system X more or less dependable than system Y?
人们通常将可靠性视为一个整体，并普遍认为可靠性越高越好。在 IEEE P982 工作组的研究和讨论过程中，我们被这样一个想法所吸引：将可信赖性表征为一个由其组成指标（可靠性、可用性、可支持性和可恢复性）得出的单一数字分数：在连续的系统版本中它是否发生了变化？在多大程度上 X 系统比 Y 系统更可靠或更不可靠？
