Design of experiments are crucial in planning, conducting, analyzing and interpreting controlled experiments to determine which factors are the most effective in controlling the value of a parameter(s).
By planning and strategically implementing experiments, researchers could gather really useful information of the effect(s) on a response variable due to one or more factors.
The main concepts in designing a DOE include blocking, randomization and replication.
In order to begin a DOE, researcher should identify:
- Key factors
- Settings that could affect performance
- Are there any interactions expected
- How to minimize variation in output
- Screening designs
- A response surface design
- Mixture Designs
