Design Optimization on Cost Basis Using Orthogonal Arrays

Abstract

This paper describes the approach used in a cost optimization study for a single-stage-to-orbit launch vehicle. Taguchi's experimental designs called orthogonal arrays are utilized for efficiently studying the effect of different material and technology options on design, development, test and evaluation cost. The results suggest that the approach taken facilitates rapid evaluation on a cost basis early in the design phase and may lead to reduced project costs.
