The Operations Research and Systems Analysis group is a multidisciplinary team of engineers and applied mathematicians who formulate and analyze mathematical models of complex systems in order to enhance performance. We use a wide range of mathematical and computational approaches including optimization, stochastic modeling, simulation, algorithms, and graph theory. The modeling and analysis performed is broadly applicable and is currently being used to solve problems in areas such as chemical, biological, radiological and nuclear terrorism, cyber security, power systems and energy grids, and nuclear enterprise planning.
