EVALUATION OF THREE DECOMPOSITION MDO ALGORITHMS

Abstract

Three decomposition MDO algorithms, Collaborative Optimization (CO), Concurrent Subspace Optimization (CSSO) and Bi-Level Integrated System Synthesis (BLISS) have been evaluated based on two typical applications. It shows that the BLISS is efficient for both applications. The CO is suggested to be more suitable for systems with little coupling between disciplines. The efficiency of the CSSO mainly depends on the construction of the simulation models.
