Operations Research (OR) is the professional discipline that deals with the application of information technology for informed decision-making. OR professionals aim to provide rational bases for decision
making by seeking to understand and structure complex situations and to use this understanding to predict system behavior and improve system performance. Much of this work is done using analytical and
numerical techniques to develop and manipulate mathematical and computer models of organizational systems composed of people, machines, and procedures.
Operations Research draws upon ideas from engineering, management, mathematics, and psychology to contribute to a wide variety of application domains; the field is closely related to several other fields
in the “decision sciences” — applied mathematics, computer science, economics, industrial engineering, and systems engineering.
Operations Research is distinguished by its broad applicability and by the wide variety of career opportunities and work styles it embraces. Because the concepts and methods of OR are so pervasive,
operations research offers highly flexible career paths.
