开发了一种用于分析优雅退化和备用计算机系统的可靠性的模型。该模型的基础是识别崩溃的四个不同原因：时间域多个故障，资源耗尽，空间域多个故障和孤立故障。为这些引起崩溃的机制及其相互关系开发了表达式。然后，通过使用它来分析称为Prime的优雅计算机系统的可靠性来证明该模型。
A model for analyzing the reliability of gracefully degrading and standby-sparing computer systems is developed. The basis of the model is the identification of four distinct causes of crashes: time-domain multiple faults, resource exhaustion, space-domain multiple faults, and solitary faults. Expressions are developed for each of these crash-causing mechanisms and for their interrelationship. The model is then demonstrated by using it to analyze the reliability of a gracefully degrading computer system called PRIME.
