Hello, A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee. Applicant's name: Jonathan Ozik Applicant's institution: ANL Applicant's division: DIS Project Name: gcmat Project title: Global Critical Materials Modeling Associated funding: DOE Office of Energy Policy and Systems Analysis DOD Defense Logistics Agency Other Systems: Science: This project uses adaptive simulation methods to compute sensitivity and uncertainty ranges for predicting global price and production of critical materials needed for clean energy technologies. Project description: We will use agent-based modeling to study the effects of producer and consumer decisions on market dynamics. Also, we intend to understand the effects of critical parameters on model outcomes. We will use Repast Simphony for agent-based modeling and the Swift parallel scripting workflow language for constructing adaptive workflows. Our goal is to advance methods for adaptive simulation experiments that will be widely applicable to many kinds of models. We will carry out parameter sweeps over 100k+ to 1M+ parameter combinations, determining regions of parameter space that exhibit the best fit to empirical data, including historical prices of critical materials, and parameter sensitivity. The adaptive simulation workflows will allow us to strategically explore large parameter spaces, dynamically generating parameter combinations based on results of distributed simulation runs.
