DOE: Screening Experiments Training
Learners will be able to:
- Describe the family of DOEs and explain the objective of each.
- Conduct a Plackett-Burman screening experiment.
- Conduct a Taguchi screening experiment.
About This Course
Screening Experiments are the most powerful of Design of Experiments techniques for uncovering the power factors in a manufacturing process. With a small number of experimental runs and very little data, you can make significant improvements to processes. The most common screening experiment techniques – Taguchi and Plackett-Burman techniques are covered in detail in this course.
Now you can learn how to conduct DOE screening experiments with this comprehensive online training program in the comfort of your own office. By learning the powerful Design of Experiments techniques developed by Plackett-Burman and Taguchi you will be able to set-up and conduct your own in-house DOE screening experiments without outside consultants or seminars.
Because this training is self-paced, you can develop your own experimental design as you go through the training. DOE worksheets and step-by-step DOE instructions will guide you through the process. If your company is implementing a lean six sigma initiative, you know how important it is to optimize your manufacturing processes with DOE. This Design of Experiments training course will give you the tools you need to get the most from this powerful statistical quality improvement technique.
