Informative experimental design for electronic circuits

摘要

this paper presents the case against two widespread practices in designing engineering experiments, which are (i) to vary one factor at a time (the OFAT approach) and (ii) to generate experimental points by a random selection (the Monte Carlo approach). These approaches do not produce good experimental designs, defined as generating maximum information per fun (IPR), and should be replaced by designs that do these latter designs (I) vary many factors t a time and (iii) use a patterned set of experimental points rather than a random set. An example form circuit design is used to illustrate this approach. The limitations of the random approach are well known amongst statisticians but often not among engineers.
