“…Other studies explore network metrics to characterize the overall robustness of a system (or an SoS) to the removal or loss of a node or an edge (e.g., a CS removal or an interaction loss between two CSs). For instance, Antul et al, (2017) represents an SoS as the network of its CSs and measures the algebraic connectivity to capture "a network's vulnerability to disconnection (e.g., removal of a CSs)." In a similar fashion, the robustness coefficient has been used in the literature (Haley et al, 2016;Paparistodimou, Duffy, Whitfield, Knight, & Robb, 2020;Walsh et al, 2019) and characterizes the largest connected component (connected nodes) after a node removal (e.g., removal of a CS in an SoS or the loss of a function).…”

“…Though these metrics do not quantify resilience (since they do not explicitly account for recovery dynamics), they are still useful for assessing SoS architecture alternatives given the importance of robustness to resilience. Antul et al (2018) quantified the robustness of three architecture variations of a notional military SoS and compared observed trends from this lightweight approach to one based on running detailed simulations to characterize the performance of the same architectures. Virtual simulation experiments provided evidence of the predictive value of the graph-theoretic metrics for SoS analysis.…”

“…The notional scenario considered for network robustness analysis. The critical asset is in the center, with red lines indicating undetected threat aircraft and green dots representing successfully intercept threats (Antul et al 2018 Antul et al (2018) challenges above. A structured approach to establishing goals and evaluation criteria is a critical early step in trade-off analysis, and SVN modeling shows potential for elucidating stakeholder priorities in an SoS context with conflicting objectives.…”
