Operations Research (OR) is a graduate program of an interdisciplinary nature, governed by an administrative board and the program committee, and administered through the office of the program director.Operations research, also known as management sciences, uses scientific methodology to study systems whose design or operation requires human decision-making. OR provides the means for making the most effective systems design and operation decisions. The strength and versatility of OR stem from its diagnostic power through observation and modeling and its prescriptive power through analysis and synthesis.OR is interdisciplinary, drawing on and contributing to the techniques from many fields, including mathematics and mathematical sciences, engineering, economics and the physical sciences. OR practitioners have successfully solved a wide variety of real-world problems, varying from the optimal design of telecommunications networks in uncertain demand to the planning for an optimal deployment of armed forces during wartime. Many new applications originate from current societal energy production and distribution problems, environmental pollution control, health maintenance, and software production.
