Design optimization on cost basis using taguchi's orthogonal arrays

摘要

This paper describes the approach used in a parameteric cost optimization study of a reusable s ingle-stage-to-orbit launch vehicle. Different material and technbology options aer studied to optimize vehicle per-formance and cost. This opt8mization study is performed using Taguchi's orthogonal arrays. The results suggest that the approach taken facilitate evaluation on ocst basis and may provide valuable information to engineers and managers early in the design phase.
