• Doctoral students majoring in operations research concentrate in one of three areas. Doctoral students also select two minor subjects for the Ph.D. degree, one of which must be outside the field. 
  • A minor may be in operations research or in a subject offered in another field, such as computer science, econometrics and economic statistics, environmental systems engineering, managerial economics, mathematics, or planning theory and systems analysis.
  • In addition to the examinations required by the Graduate School, the field requires a qualifying examination for Ph.D. degree candidates, normally taken in the third term of graduate study at Cornell.
