    • Multidisciplinary Optimization of a Supersonic Transport Using Design of Experiments Theory and Response Surface Modeling 

      Giunta, Anthony A.; Balabanov, Vladimir; Haim, Dan; Grossman, Bernard; Mason, William H.; Watson, Layne T.; Haftka, Raphael T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1997-07-01), TR-97-10
      The presence of numerical noise in engineering design optimization problems inhibits the use of many gradient-based optimization methods. This numerical noise may result in the inaccurate calculation of gradients which ...
    • Suitability of Optimization Packages for an MDO Environment 

      Haim, Dan; Giunta, Anthony A.; Holzwarth, M; Mason, William H.; Watson, Layne T.; Haftka, Raphael T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1996-10-01), TR-96-18
      An examination of the performance of several optimization packages and their suitability for inclusion in a realistic multidisciplinary design optimization (MDO) environment is conducted. The packages are incorporated into ...
    • Wing Design for a High-Speed Civil Transport Using a Design of Experiments Methodology 

      Giunta, Anthony A.; Balabanov, Vladimir; Haim, Dan; Grossman, Bernard; Mason, William H.; Watson, Layne T.; Haftka, Raphael T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1996-07-01), TR-96-12
      The presence of numerical noise inhibits gradient-based optimization and therefore limits the practicality of performing aircraft multidisciplinary design optimization (MDO). To address this issue, a procedure has been ...
