Summary

[edit]
Description
English: Design of experiments; Doehlert method used.

2 factors (X1: curing time in min; X2: curing temperature in °C); 7 trials; Y: property of the material (response).
Matrix of the trials:
N - X1 - X2
1 - 25 - 180
2 - 35 - 180
3 - 15 - 180
4 - 30 - 206
5 - 20 - 206
6 - 30 - 154
7 - 20 - 154
Result: Estimated response surface; Y estimated for a 95% confidence level; corresponding polynomial model.

Parabola effect with X2.
Français : Plan d'expériences ; réseau de Doehlert utilisé.

2 facteurs (X1 : durée du palier de cuisson, de 15 à 35 min ; X2 : température du palier de cuisson, de 154 à 206 °C) ; 7 essais ; Y : propriété (grandeur physique) du matériau étudié (réponse).
Plan des essais :
N - X1 - X2
1 - 25 - 180
2 - 35 - 180
3 - 15 - 180
4 - 30 - 206
5 - 20 - 206
6 - 30 - 154
7 - 20 - 154
Résultat : surface de réponse estimée ; Y estimé avec un niveau de confiance de 95 % ; modèle polynomial correspondant.
