Toward dynamic evaluations of materials criticality: A systems framework applied to platinum

A criticality assessment framework is introduced to quantitatively evaluate mineral supply-risk drivers, end-user vulnerabilities, market-dynamic indicators, and their interconnections in a time-dependent manner. Using this framework, we analyzed the criticality of platinum from 1975 to 2015, considering major regional end users (Europe, North America, Japan, and China) and producers (South Africa and Russia). Our analysis demonstrates that: (1)...
