Abstract : The large number of factors commonly encountered in simulation and live field test programs dictates that a large (and costly) experimental program be run if the classical full factorial experimental design is employed. Through the use of a screening process involving a sequential design, efficient economical pilot studies can be conducted, leading to a reduction in the number of factors and the size of the experimental space. Fractional factorial designs are used in the pilot studies. The experimental data provide guidance to the experimenter in terms of removing nonsignificant factors and thus reducing the size of the experimental space. This report documents the initial design, development, and use of an interactive computer program to aid in the development of fractional factorial experimental designs. Fractional factorial experiments are a special class of experimental procedures that allow the user to perform a smaller number of experiments than would be required in the usual experimental procedures and which maximize information return while minimizing the number of observations (tests) required. The overall experimental design philosophy is described and a brief introduction into the theory of experimental design is presented. The Appendix describes how the computer program was constructed and how it should be used. A specific example related to the MISVAL (Missile Launch Envelope Technology Program) is included. (Author)
