(PDF) Optimizing Mining Supply Chains under Uncertainty
This concept is then extended to mining supply chain optimization under geological uncertainty, where the clustering is performed over a set of simulations, leading to more robust long-term decision making. A particle swarm optimization algorithm for optimizing the proposed mining supply chain models is then discussed.
