Design of Experiments - DOE - Unit 4 - SRMIST Syllabus

RSM

A sequential procedure is a collection of statistical techniques for the analysis of problems in which the response is influenced by other variables. The objective is to optimize the response.

  1. First-order model - A linear function of independent variables.
  2. Second order model - Curvature of a polynomial of higher degree.
  3. Contour Plot - A 2-D projection of the curvatures.

Canonical form & optimization.


Types

    1. Steepest Ascent - Upward of region of fitted.
    2. Steepest Descent - Downward of the region of fitted.

Central Composite Designs

  1. Fractional factorial
  2. Plackett-Burman
  3. Box-Behnken

Design Points

    1. CCC
    2. CCI
    3. CCF

NOTE

*Certain sums are possible from this unit which has not been mentioned in this article.
