Abstract:

Several visualizations have been proposed in the covering array literature for assessing the coverage properties of these designs. Some of these visualizations have been adapted from correlation plot structures. In this talk, a new visualization technique will be introduced that utilizes a different approach based on column projections of designs. Originally developed for general experimental designs, these visualizations have been found to also have desirable properties for covering array designs. One area of application makes use of “don’t care positions,” which are positions whose values can be changed without affecting the covering property of the design. By using “don’t care positions,” this technique provides a way to visualize how a covering array design can be improved while ensuring that its covering property is preserved.
