What is Operations Research?

Operations Research (OR) is the analysis-usually involving treatment-of a process, problem, or operation to determine its purpose and effectiveness and to gain maximum efficiency.
The strength and versatility of OR lie in its ability to model the behavior of complex systems in quantitative mathematical terms, as well as its prescriptive power through analysis and synthesis.

Operations Research is interdisciplinary by nature and draws on the techniques from many fields, including the mathematical sciences, engineering, the solution economics, and the physical sciences.

Applied Optimization Lab

The mission of the Applied Optimization Lab is to conduct high quality academic research while addressing real industrial and government problems. Research activities are focused on the use and development of advanced computer software to analyze and optimize performance measures of actual systems. The lab’s faculty participants have a unique combination of expertise and experiences that allow them to address complex problems in logistics, transportation, and renewable energy systems, stochastic modeling and analysis of manufacturing systems, facility layout and location, and network design and optimization.
