A valid model is one that accurately represents the problem or system under investigation. A robust model is one that gives reliable results even with small changes in inputs or assumptions; a sensitive model is one that is highly impacted by small changes in inputs or assumptions; an optimal model is one that maximizes or minimizes a specific objective function; a feasible model is one that can be implemented in practice. While these other characteristics are important, they do not necessarily guarantee accuracy and correctness in representing the problem or system.
