1. all of the above.........

Answer 2

Operation research involves all the three models namely mathematical, economical and statistical.

• Operations Research is an analytical method for problem-solving and decision-making which is useful for organizational management.
• Problems are broken down into basic components in operations research, and then solved by mathematical analysis as per the defined steps.
• Many research studies of operations include the creation of mathematical and statistical models. The model is a set of mathematical and logical relationships which reflects aspects of the situation under analysis.
• Models explain the relationships between variables, and also include an objective function that evaluates the alternative solutions and constraints which restrict solutions to feasible values.
