What are the best schools for operations research?

<p>I know that Berkeley has a department (joint w/ industrial engineering) Case Western too, Stanford, Toronto. I suspect the best engineering, or science/math schools have good operations research. I think its more of a graduate track no? Does anyone know which are the best departments?</p>

<p>I think Cornell's is highly thought of, but I've never seen a ranking. They have undergrad and graduate tracks. Look at
