提出了一种基于copula的容错系统模型中组件间依赖关系的处理方法。这些依赖关系包括具有共同原因的故障、故障传播、有限的修复能力、由于修复而导致的破坏或故障后的过载，并且应该包括在任何可靠性/可用性分析中，以避免过度乐观的结果。本文包含了所提出的方法的概念以及它在工具COBAREA（基于copula的可靠性和可用性建模环境）中的实现的信息。两个例子说明了所建议的方法。
A novel method, based on copulas, for dealing with inter-component dependencies in models for fault-tolerant systems is presented. These dependencies include failures with a common cause, failure propagation, limited repair capacity, destruction due to repair, or overload after a failure and should be included in any reliability/availability analysis to avoid over-optimistic results. The paper contains information both on the concepts of the proposed method as well as on its implementation in the tool COBAREA (COpula-BAsed REliability and Availability modeling environment). Two examples illustrate the proposed approach.
