we propose a supply chain strategic resiliency index (SRI) to comprehensively measure strategic SCR. The index integrates the consideration of supply network structure, supplier reliability (especially geopolitical risks), and each supplier’s contribution of material flow into a unified metric. Such an index can serve three primary purposes: (1) benchmarking the resilience of the existing supply chain, (2) evaluating the impact of strategic supply chain management decisions, and (3) assessing the resilience impact of new technology developments. As a use case, we analyzed the lithium supply chain of U.S. electric vehicle manufacturers, utilising real-world lithium imports and vehicle production data. Our results show that automakers are increasing their SCR, as exemplified by General Motors’ SRI increase from 27 in 2022 to 59 in 2023, and further to 65 in 2024.
