摘要

本文提出了一种利用不可分割的系统故障和恢复数据集的排列来计算系统可用性和可靠性概率分布的方法。这些数据集通常来自系统历史，反映在诸如日常生产之类的性能度量中。在任何失败及其后果之间保持直接关系;也就是说，故障间隔时间(TBF)和恢复时间(TTR)是不可分割的集合。此外，TTR不必是单值的，而可以采用另一个数据集的形式，以适应系统退化和相关故障。

Probabilistic assessment of availability from system performance data

This paper presents a method of calculating system availability and reliability probability distributions using permutations of inseparable system failure and restore data sets. Such data sets usually come from system history, as reflected in a performance measurement such as daily production. A direct relationship is maintained between any failure and its consequence; that is, time-between-failure (TBF) and time-to-restore (TTR) are an inseparable set. Furthermore, TTR need not be single-valued but may take the form of another data set to accommodate system degradation and dependent failures.
