Multi-level design experiments are used to evaluate multiple factors set at multiple level. Unlike, two level design, multi-level design can have more than two levels for a particular factor/treatment. Various criteria are available to evaluate the optimality of such a design, such as measure of Non Orthogonality of Design. You can also generate the optimal design according to these criteria using Smart Design.

To generate an optimal super-saturated design with respect to different criteria, you can choose from the options available from the list that appears on clicking the button in the top left of this description.
