本文提出了一种系统的基于模型的方法来描述系统中的故障和容错机制。设计可靠的soa所面临的挑战激发了对视图元素的建议，这些元素需要使用系统建模语言（SysML）来支持soa的容错配置文件。通过一个基于真实应急SoS的案例研究，评估了该方法的有效性。结果表明，这是一种很有前途的方法，并且可靠的sos工程的综合解决方案需要将这样的概要文件与需求引出、安全分析、架构设计和正式验证的方法和工具联系起来。
This paper proposes a systematic model-based approach to the architectural description of faults and fault tolerance mechanisms in systems of systems (SoSs). The challenges of engineering dependable SoSs motivate a proposal for the view elements that would be needed to support a fault tolerance profile for SoSs using the Systems Modelling Language (SysML). The effectiveness of the approach is evaluated on a case study based on a real emergency response SoS. Results suggest that this is a promising approach, and that a comprehensive solution to the engineering of dependable SoSs requires that such a profile is linked to methods and tools for requirements elicitation, safety analysis, architectural design and formal verification.
