Which of the following best explains the modeling approach of research design?

AThe research problem is represented by a mathematical model and the solutions are derived from that model. ✓ Correct

BThere is no research problem and the solutions are derived from the objectives.

CIt is carried out in a subjective manner and the solutions come from the research questions.

DIt is carried out in an objective manner and the solutions come from the research methodology.

Correct answer: (A) The research problem is represented by a mathematical model and the solutions are derived from that model.

Explanation

In the modeling approach the research problem is represented by a mathematical model and the solutions are derived from that model.

Saying there is no research problem and solutions come from objectives misdescribes the approach.

Being carried out subjectively with solutions from research questions is not modeling.

Deriving solutions from research methodology in an objective manner does not define modeling.

Modeling uses formal mathematical relationships to represent and solve the problem.

Operations research and simulation often rely on such modeling designs.
