Supply chain risk management for critical commodities: A system dynamics model for the case of the rare earth elements
Michael L. Keilhacker, Stefan Minner 0 0 04/05/2017 00:00:00
We apply a system dynamics approach to examine the individual company’s reaction in the rare earth elements (REEs) supply chain to China’s introduction of export restrictions over a three-stage supply chain for 11 REEs, 10 semi-finished goods (SFG), and 21 finished goods (FG) between 2004 and 2015. We analyze how FG and SFG substitution, secondary recycling, supply extension and research and development (R&D) affect dynamic variables such as the price level, supply and demand on each stage to determine the effectiveness of each strategy for mining companies, SFG and FG producers.
