## What is Operations Research?

Operations research (OR) is the mathematical study of resource allocation problems, decisions, games, uncertainty, scheduling, and optimization.

The various sub-disciplines of OR yield both analytic and computational tools that allow for mathematical modeling and efficient problem-solving.
