摘要 本文的目的是概述过去几十年中发展的各种可靠性概念。本文首先总结了为衡量网络可靠性而开发的各种指标，然后研究了计算这些指标的技术。讨论了不同指标的有用性和局限性。本文认为，不存在单一的完美指标，但指标和技术的选择取决于几个因素，包括分析师的观点以及正在考虑的干预措施的类型和范围。为了评估事件的影响，作者建议区分三种类型的干预，即“仁慈”、“中立”或随机以及“恶意”。还讨论了为什么在试图最大程度地减少事件影响时向旅行者提供最新信息可以发挥核心作用。
Abstract The objective of this paper is to give an overview of various reliability concepts that have been developed in the last decades. The paper first summarises various indicators that have been developed in order to measure the reliability of a network and then looks at techniques to calculate these indicators. The usefulness and limitations of the different indicators is discussed. The paper suggests that there is no single perfect indicator but that the choice of indicator and technique depends on several factors, including the viewpoint of the analyst and the type and range of interventions being considered. In order to assess the impact of incidents the authors propose to distinguish between three types of intervention, namely “benevolent”, “neutral” or random, and “malevolent”. Also discussed is why the provision of up-to-date information to the traveller has a central role to play when trying to minimise the impact of an incident.
