Design of Experiments (DOE) I: Introduction to DOE

Register / Course Info

Design of Experiments (DOE) allows calculation of the equations that relate output(s) and the variability of output(s) to the input variable levels. Learn the techniques for planning studies in which the inputs to a system/process can be varied and the outputs observed. Explore efficient planning and analysis methods for determining which inputs have statistically significant effects on outputs and output variability, including analysis of variance, full and fractional factorial experiments, randomization, robust design and sensitivity analysis.

Dr. Steven (Flash) Gordon is the director of TEREC and the Orlando Field Office Manager for Georgia Tech Research Institute. He served over 26 years in uniform in the United States Air Force (USAF) in various assignments, including as an aircrew member and instructor in the F-111, Director of Air Operations Centers, Division Chief on the Air Staff, and Professor and Head of the Department of Mathematical Sciences at the USAF Academy. At the Academy, he taught pre-calculus, calculus I-III, linear algebra, probability and statistics, systems of differential equations, and design of experiments. He also served over 4 years as the Technical Director for the Air Force Agency for Modeling and Simulation. He has a BS in Mathematics from Marymount College of Kansas, MS in Human Development Counseling/Education from Peabody College of Vanderbilt University, MS in Industrial Engineering/Operations Research from Purdue University, and a PhD in Aeronautical and Astronautical Engineering from Purdue University. His PhD research topic was orbit determination and optimal control of Earth-Moon-Sun libration point spacecraft orbits, and this research was extended to include experimental design for libration orbit control cost excursions.
