Abstract Recent developments in modern cyber-physical systems (CPSs) have allowed greater levels of intelligence and flexibility. The high levels of interactions and interdependencies in CPSs, however, also increase their vulnerabilities to external attacks and internal malfunctions. Disruptions in one cluster of a CPS can propagate to another cluster, eventually compromising the entire CPS if protective mechanisms and preparations are insufficient. The economic impacts are immediately local, but will become global should response mechanisms prove insufficient. Ensuring CPS resilience against disruption propagation requires the appropriate strategic preparation of response mechanisms, which is studied in this article. Recent work in CPS disruption response, notably the Collaborative Response to Disruption Propagation (CRPD) framework, has established the foundations for modeling and comprehension of the disruption response problem. Building upon the CRDP framework, this research introduces the Collaborative Response to Disruption Propagation/Strategic Lines of Collaboration (CRDP/SLOC) to investigate the effects of selecting different response agent teams to tackle disruptions. This selection is a strategic decision that cannot be altered once the disruptions begin, and thus needs to be guided by an appropriate collaborative control principle, called the SLOC principle. The SLOC principle analyzes the network structure, incorporates disruption propagation knowledge, and evaluates the strategic compatibility of the response agent teams to guide the selection and preparation process. The CRDP/SLOC model is validated using a set of experiments with different factors. These experiments indicate that the teams selected with the SLOC principle outperform the baseline teams in terms of response performance and resilience.

通过网络物理系统响应中断传播 (CRDP) 的战略协作线

摘要 现代网络物理系统 (CPS) 的最新发展允许更高水平的智能和灵活性。然而，CPS 中高度的交互和相互依赖性也增加了它们对外部攻击和内部故障的脆弱性。如果保护机制和准备不足，一个 CPS 集群中的中断可以传播到另一个集群，最终损害整个 CPS。经济影响立即是局部的，但如果反应机制证明不足，则将成为全球影响。确保 CPS 对中断传播的弹性需要对响应机制进行适当的战略准备，本文将对此进行研究。最近在 CPS 中断响应方面的工作，特别是对中断传播的协作响应 (CRPD) 框架，为中断响应问题的建模和理解奠定了基础。本研究以 CRDP 框架为基础，引入了对中断传播/战略协作线 (CRDP/SLOC) 的协作响应，以研究选择不同响应代理团队来应对中断的影响。这种选择是一个战略决策，一旦中断开始就不能改变，因此需要以适当的协作控制原则为指导，称为 SLOC 原则。SLOC 原理分析网络结构，结合中断传播知识，评估响应代理团队的战略兼容性，以指导选择和准备过程。CRDP/SLOC 模型使用一组不同因素的实验进行验证。
