Operations research (also referred to as decision science, or management science) is an interdisciplinary mathematical science that focuses on the effective use of technology by organizations. In contrast, many other science & engineering disciplines focus on technology giving secondary considerations to its use.

É usada sobretudo para analisar sistemas complexos do mundo real, tipicamente com o objectivo de melhorar ou optimizar a performance.
