The Convergence of Mathematical Analysis and Improved Decision Making

The School of Operations Research and Information Engineering at Cornell is consistently placed among a handful of leading Operations Research programs worldwide. Our program fosters an intense collaborative research community in keeping with our history of academic excellence.

Cornell’s program in Operations Research and Information Engineering is a rigorous program with approximately 225 undergraduates, 90 Master of Engineering students, and 40 Ph.D. students. Students have received a variety of awards and recognition including for example, recognition from INFORMS and SIAM and fellowships from the Hertz Foundation, National Science Foundation, National Institutes of Health, National Defense Sciences and Engineering, Department of the Navy, Department of Energy, and IBM.

ORIE focuses on fundamental principles and methods but also uses contextual learning and design experiences to integrate the science with engineering. Our approach to engineering education, both graduate and undergraduate, emphasizes broad mastery of core areas of the discipline:

  • methods of optimization
  • applied probability modeling and statistical analysis
  • manufacturing systems design and operation
  • systems analysis and methodology.

We invite you to join us!

Did you know?

1972 – Jack Muckstadt (still active as a Cornell faculty member) develops the mathematical basis for determining the number and allocation of spare parts needed to repair aircraft having multiple indentured level subsystems (e.g., engines and avionics systems). This multi-echelon mathematical approach is used by all military services in the US and by militaries in many other countries. It has been used to manage and procure well over $100B of parts in the US since 1973.
