## Operations Research MCQ

Operations research (OR) is an analytical method of problem-solving and decision-making that is useful in the management of organizations. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical analysis.

Operations Research is the science of rational decision-making and the study, design, and integration of complex situations and systems with the goal of predicting system behavior and improving or optimizing system performance.
