This article explains how to analyze supply chain risk using network graphs, moving beyond simple supplier lists. It details how to model nodes as legal entities, sites, or parts, with edges representing material flow. The author highlights the limitations of degree centrality, which only counts relationships, and introduces betweenness centrality as a measure that identifies nodes crucial for shortest paths. Ultimately, the piece argues that while centrality measures are useful, they can obscure critical vulnerabilities like articulation points (cut vertices) and bridges (cut edges), which are essential for understanding network survival.
