Abstract : In this study, repetitive response surface enhancement technique (RRSET) is proposed as anew system approximation method for the efficient multidisciplinary design and optimization(MDO). In order to represent the highly nonlinear behavior of the response with second orderpolynomials, RRSET introduces a design space transformation using stretching functions andrepetitive response surface improvement. The tentative optimal point is repetitively includedto the set of experimental points to better approximate the response surface of the systemespecially near the optimal point, hence a response surface with significantly improvedaccuracy can be generated with very small experimental points and system iterations. As asystem optimizer, the simulated annealing, a global optimization algorithm is utilized. Theproposed technique is applied to the several numerical examples, and demonstrates thevalidity and efficiency of the method. With its improved approximation accuracy, the RRSETcan contribute to resolve large and complex system design problems under MDO environment.
