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.
