Operations research is a field of study that uses mathematical and analytical methods to help make better decisions. It involves techniques such as optimization, simulation, and statistical analysis to solve complex problems in various industries, including transportation, healthcare, and manufacturing. The goal of operations research is to improve efficiency and effectiveness by finding the best possible solutions to problems. By modeling real-world scenarios, it helps organizations allocate resources, schedule tasks, and manage supply chains more effectively, ultimately leading to cost savings and improved performance.
