Coming Soon

The Definitive Screening Design Assistant helps you create efficient screening designs for identifying important factors in your experiments.

We're currently modernizing this tool to provide an enhanced, interactive experience. Check back soon!

What This Tool Will Do

Definitive Screening Designs (DSDs) are revolutionary three-level designs that identify important factors and estimate quadratic effects in remarkably few runs.

This assistant will help you:

  • Specify the number of factors to screen
  • Generate optimal three-level screening designs
  • Minimize the required number of experimental runs
  • Estimate main effects, two-factor interactions, and quadratic effects
  • Efficiently screen large numbers of factors

Why Definitive Screening Designs?

Extremely efficient: Screen many factors in just 2m+1 runs (where m = number of factors). For 6 factors, only 13 runs needed!

More information: Unlike traditional screening designs, DSDs can estimate quadratic (curvature) effects, not just main effects and interactions.

No confounding: Main effects are not confounded with two-factor interactions or quadratic effects, giving you clearer results.

Three-level design: Tests each factor at low, medium, and high levels, capturing more information about factor behavior.

When to Use DSDs

Early in development: When you have many potential factors and need to identify which ones are important.

Limited resources: When you need maximum information with minimum experimental runs.

Curvature suspected: When you expect non-linear (quadratic) effects in your response.

Follow-up optimization: As a first step before a full response surface design focusing on active factors.
