Multidisciplinary Optimization Design of the Submarine based on Collaborative Optimization Algorithm

Distributed Multidisciplinary Design and Collaborative Optimization

1. Summary These notes describe some recent ideas for distributed design and their application to large-scale aerospace systems. In this type of multidisciplinary optimization, design tasks are decomposed into domain-specific subproblems, and coordinated to achieve an optimal system. Focusing on collaborative optimization, one form of design decomposition, the notes detail the methods, summariz...

An Approach Based on Enhanced Collaborative Optimization and Kriging Approximation in Multidisciplinary Design Optimization

This paper concentrates on the computational challenge in multidisciplinary design optimization (MDO) and a comprehensive strategy combining enhanced collaborative optimization (ECO) and kriging approximation models is introduced. In this strategy, the computational and organizational advantages of original collaborative optimization (CO) are inherited by ECO, which can satisfy the strengthened...

Collaborative Multidisciplinary Design Optimization for Conceptual Design of Complex Products

Multidisciplinary Design Optimization

Multidisciplinary design optimization (MDO) is a field of engineering that focuses on use of numerical optimization to perform the design of systems that involve a number of disciplines or subsystems. The main motivation for using MDO is that the best design of a multidisciplinary system can only be found when the interactions between the system's disciplines are fully considered. Considering t...

Global Optimization Algorithms in Multidisciplinary Design Optimization

While Multidisciplinay Design Optimization (MDO) literature focuses mainly on the development of different formulations, through the manipulation of design variables, less attention is generally devoted to the combination of specific MDO formulations with existing nonlinear optimization algorithms. In this paper, the focus is on the application of a Global Optimization (GO) algorithm to an MDO ...
