Industrial engineering, operations research, and systems engineering are fields of study intended for individuals who are interested in analyzing and formulating abstract models of complex systems with the intention of improving system performance. Unlike traditional disciplines in engineering and the mathematical sciences, the fields address the role of the human decision-maker as key contributor to the inherent complexity of systems and primary benefactor of the analyses.

Ellis Johnson a Professor Emeritus in Stewart School of Industrial and Systems Engineering. He received a B.A. in mathematics at Georgia Tech and a Ph.D. in operations research at the University of California. Before joining Georgia Tech in 1995, he was at IBM's T.J. Watson Research Center for 26 years. There, he founded and managed the Optimization Center from 1982 until 1990, when he was named IBM Corporate Fellow. In 1980-1981, he was at the University of Bonn, Germany, as recipient of the Alexander Von Humboldt Senior Scientist Award. In 1984, he received the George Dantzig Award for his research in mathematical programming. In 1986, he was awarded the Lanchester Prize for his paper with Crowder and Padberg. In 1988, he was elected to the National Academy of Engineering. In 2000, Dr. Johnson won the INFORMS John Von Neumann Theory Prize. From 1990 to 1995, he began teaching and conducting research at Georgia Tech, where he co-founded and co-directed the Logistics Engineering Center with Professor George Nemhauser.
Dr. Johnson's research interests in logistics include crew scheduling and real-time repair, fleet assignment and routing, distribution planning, network problems, and combinatorial optimization.
