Design and analysis of experiment (DOE)
This module designs a two-level multifactorial orthogonal plan 2^(n–k) and perform its analysis. The DOE module has two parts, Design for the experimental design before carying out experiments which will find optimal combinations of factor levels to gain maximum information at a reasonable number of experiments and part Analysis which will analyse results of the planned experiment. The main goal of DOE is to find which of the factors included in the model have considerable influence on one outcome of the experiment. The outcome is called response and it can typically be yield, energy consumption, costs, rate of non-conforming product units, blood pressure etc.
