​Design Expert 實驗設計軟體

Stat-Ease, Inc. 歡迎您使用 Design-Expert version 9 (DX9) 來做實驗設計,使用視窗界面的程式來最佳化您的流程或產品。它提供了很多功能強大的統計工具如::
  • Two-level factorial screening designs: Identify the vital factors that affect your process or product so you can make breakthrough improvements.
  • General factorial studies: Discover the best combination of categorical factors, such as source versus type of raw material supply.
  • Response surface methods (RSM): Find the optimal process settings to achieve peak performance.
  • Mixture design techniques: Discover the ideal recipe for your product formulation.
  • Combinations of process factors, mixture components, and categorical factors: Mix your cake (with different ingredients) and bake it too!
Your Design-Expert program offers rotatable 3D plots to easily view response surfaces from all angles. Use your mouse to set flags and explore the contours on interactive 2D graphs. Our numerical optimization function finds maximum desirability for dozens of responses simultaneously!

You'll find a wealth of statistical details within the program itself via various Help screens. Take advantage of this information gold mine that is literally at your fingertips. Also, do not overlook the helpful annotations provided on all reports.

For a helpful collection of checklists and "cheat sheets," see the Handbook for Experimenters. It's free to all registered users. Furthermore, for quick primers on the principles of design and analysis, we recommend you read the following two soft-cover books from Stat-Ease Principals Mark Anderson and Pat Whitcomb,  published by Productivity Press of New York city:
  • DOE Simplified: Practical Tools for Effective Experimentation,
  • RSM Simplified: Optimizing Processes Using Response Surface Methods for Design of Experiments.
Anderson and Whitcomb have also written a Primer on Mixture Design. It's posted free for all to read via the "I'm a Formulator" link on the Stat-Ease home page.
