System dynamics modeling of the global nickel supply system at a mine‐level resolution: Toward prospective dynamic criticality and resilience data

Journal of Industrial Ecology, Volume 29, Issue 5, Page 1666-1683, October 2025.
Abstract Securing the availability of enough metals to fulfill demand is a critical societal concern. Models of metal supply systems can help enhance our understanding of these systems and identify strategies to reduce material criticality and improve resilience. In this work, we introduce a novel approach to modeling metal supply systems, using nickel
