Supply Chain Mapper

Live demo, synthetic data

Which suppliers look safe on a scorecard but would take the network down?

A semiconductor supply chain modelled as a graph: five tiers of companies, the countries they sit in, and the shipping chokepoints their goods pass through. It compares a traditional per-supplier risk scorecard with network metrics to find hidden cascade points, then simulates how a shock spreads week by week.

Supply Chain Mapper risk ranking comparing each supplier’s scorecard rating with its network criticality.

What it does

Network score blends betweenness, reverse PageRank weighted by supply share, and downstream reach.
Validates itself: each supplier is removed in a Leontief model and lost output is measured. The network score tracks that impact; the scorecard does not.
Shipping chokepoints such as the Taiwan Strait, Malacca and Suez are nodes, so disruption can target a route, not just a company.
Finds fragile clusters with Louvain communities, scored on single-source dependence and country concentration.
Week-by-week shock simulator with lead-time lags, inventory buffers, surge capacity and recovery.

Built on synthetic, fixed-seed data with fictional companies.
