Redundancy and Resilience: Measures of Network Robustness

Interpopulum  |  Sean Everton, Seth Gray, Chad Machiela

Military leaders and staff require a methodology to assess network robustness before and after interventions to measure the effectiveness of their operations and campaigns, particularly for non-lethal activities and irregular warfare. Traditional performance metrics, like missiles fired or leaders engaged, often fail to indicate true mission success or reductions in adversary capabilities.

This challenge necessitates a clear distinction between network robustness, its ability to maintain functionality under stress; resilience, its capacity to recover and adapt; and redundancy, the structural condition enabling both. The paper proposes a multi-metric approach to assess network robustness, utilizing standard metrics like Average Path Length, Diameter, Largest Connected Component, and Clustering Coefficient, alongside specialized measures. This framework will be applied to two case studies: the ลปegota resistance network and the Noordin Top terrorist network, to model intervention strategies and resource allocation for both covert and overt operations.
