Operational Research (OR) is the area of study where the students learn to use advanced analytical techniques for better decision making. Sometimes it is also called as Operations Research, Industrial Engineering or Management Science. People having Master's degree (and skills) in OR are perfect for jobs in decision support, marketing analysis, business analytics and logistics planning.
