In general terms, experimental design can be applied at two levels: screening and optimization.Screening designs work with numerous variables and just a few values (2 or 3) of every variable. Its main purpose is to find out which variables are the most important, i.e. those really influencing the target parameter we want to optimize, and also …

Design of experiments (DOE) is defined as a branch of applied statistics that deals with planning, conducting, analyzing, and interpreting controlled tests to evaluate the factors that control the value of a parameter or group of parameters. DOE is a powerful data collection and analysis tool that can be used in a variety of experimental ...
