Supply chain professionals cannot visualize and predict cascading disruption effects across global trade networks
Supply chain managers, energy traders, and policy analysts lack accessible tools to model how localized disruptions (port closures, geopolitical events, sanctions) propagate through interconnected global networks and create secondary shocks in seemingly unaffected regions. Current solutions either oversimplify network effects or require expensive proprietary modeling software that doesn't capture bilateral trade dynamics and reserve depletion mechanics.

OP here: I created this visualization tool as the byproduct of a supply chain class I taught at Columbia. The pedagogical exercise grew into a full blown visualization and paper about global oil trade. The model: The mechanics are the same as the financial network Eisenberg-Noe: Instead of banks, ev...
