Operations Research MCQ
Operations research (OR) is a powerful analytical method for problem-solving and decision-making, particularly beneficial in managing organizations. In this field, problems are systematically broken down into simpler parts, solved step-by-step through mathematical analysis, making it easier to understand and implement.
Understanding Operations Research MCQ
Operations Research is the science of rational decision-making. It involves studying, designing, and integrating complex systems, aiming to understand system behaviour and enhance or optimise performance.
