Operational research, also known as operations research, is an interdisciplinary field of study that focuses on solving complex problems related to management, logistics, engineering, economics, and other domains through the application of mathematical, statistical, and computational methods. The aim of operational research is to optimize decision-making processes using techniques such as modeling, simulation, and data analysis to find the best solutions in complex and dynamic environments. This subject finds applications in various areas of life, including route planning, resource management, production optimization, as well as military strategies and rescue operations. Operational research enables informed and efficient decision-making, contributing to improved effectiveness and efficiency across different domains of activity.
