Operations Research

Operations Research (OR) is a discipline within Systems Science that applies advanced analytical methods to help make better decisions. It involves developing and using mathematical models, statistical analysis, and optimization algorithms to solve complex problems and improve the performance of systems. By taking a holistic, system-wide view, OR provides a quantitative basis for decision-making, enabling organizations to optimally allocate scarce resources, manage logistics, schedule operations, and design more efficient processes in fields ranging from business and engineering to government and public health.
