Comparative Analysis of Statistical Results of the three Approaches of Design Of Experiments (Taguchi, Classic and Shainin DOE) with A Case Study



The three methods of Design of Experiment: Taguchi ,Classic and Shainin can solve quality problem ,diagnosis the roots of quality problem and make improvement .
To use of these methods ,we should recognize the strengths and weakness of them.
Recognizing notes of these methods by comparison with a case study ,we will understand them deeper.
In this study three mentioned methods were compared after implementing ,by quantitative and conceptual criteria (those criteria were scored by experts .)
The overall results showed that Classic method has priority for implementation . Although Shainin DOE had more flexibility and less complexity than taguchi method, Taguchi method scored more because it made more improvement and needed fewer experiment so it scored more than Shainin DOE.
