Operations Research (OR) is a scientific, mathematical modeling-based approach to problem solving and management. OR is used for the efficient design and management of systems, usually seeking to determine an optimal or effective utilization and allocation of scarce resources. OR is widely used in many diverse application areas, e.g., the design and management of service and manufacturing systems, supply chain management, humanitarian logistics, healthcare and public policy.  The curriculum provides a methodological foundation, and is flexible, allowing students to focus on methodological research or applications.  More information about OR can be obtained from the Institute for Operations Research and the Management Sciences (INFORMS), the main professional society for OR, and also from the Institute of Industrial & Systems Engineers (IISE), another professional society that includes OR.

Plan of Study Requirements

A student's plan of study must include a minimum of 90 credits of coursework and graduate research.  At least 39 credits of coursework (of post BS, taken for grade) is required, including the 21 credits for the OR core courses, and at least one primary and one secondary emphasis areas.  Coursework should include at least 24 ISE credits, with at least 9 of those credits at the 6000-level. The plan of study should be designed in consultation with the student’s PhD committee. (All courses listed below are 3 credits, unless specified otherwise.)

OR Emphasis Areas

Below are some pre-defined emphasis areas.  At least 4 classes are required for a primary emphasis area, and at least 2 classes for a secondary emphasis.  Some emphasis areas have required classes. Because OR works well with methodologies traditionally from other disciplines (e.g., computer science, statistics, mathematics), and can be applied to application areas beyond those represented in the following emphasis areas, students can develop customized emphasis areas, subject to the approval of their Ph.D. committee.
