Modeling software for NAS-wide network analysis Automated network model building Graph identification techniques (pattern recognition, clustering algorithms) Aggregate flow modeling (partial differential equations, numerical analysis) Mathematical network analysis Delay multiplier analysis (Mixed Integer Linear Programming, MILP) Network sensitivity analysis (adjoint-based optimization) Automated bottleneck identification (multicommodity flows, combinatorial opt.) Decentralized ARTCC/sector optimization (dual decomposition) Control synthesis for NGATS Dynamic sectorization [collaboration with ENAC/Eurocontrol]  Reservoir management  Airborne delay mitigation  Delay multiplier mitigation

Infrastructure data (sectors, VORs, etc.)
