Industrial and Manufacturing Systems Engineering

E. Stanley Lee

2026 Durland Hall

Dr. Lee’s contributions to operations research and applied mathematics cover many different areas.  During the 1970s, he did pioneering research work in optimization theory and systems analysis with Dr. Richard Bellman and Dr. Lotfi Zadeh.  He also applied operations research techniques to solve various engineering and social problems in areas such as water resource management, alternative energy development, pollution and environmental systems, and the efficacy of nonprofit and for-profit organizations.  Recently, Dr. Lee’s interests have concentrated on the development of intelligent and soft computing techniques such as support vector machines, evidence theory, fuzzy set theory, probabilistic approaches and neural networks and on the application of these techniques to engineering and social problems.  He has made significant contributions in the areas of uncertain reasoning and artificial intelligence.  Dr. Lee joined the faculty in 1966.
