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 ...

On High Level CAD Modeling for Multidisciplinary Design and Optimization

H au IS THESIS EXPLORES novel CAD modeling methods for design reuse and tomation realization. It will be demonstrated that by applying the described methods, CAD models can be utilized as framework integrators in order to generate geometric input for various engineering analysis tools. Multidisciplinary design can as a result be facilitated in early design due to decreased manual model re-defin...

Modeling for Parametric System-Level Design Optimization

System-level design refers to a synthesis, analysis, and optimization process which reasons with the system in a holistic manner. We are developing a model-based approach to support parametric system-level design optimization. In this paper, we describe our modeling methodology based on the Environment Relationship net framework (Ghezzi et al. 1991) to represent a system for the purpose of desi...

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...

On Decomposition Methods for Multidisciplinary Design Optimization

Multidisciplinary design optimization (MDO) problems are engineering design problems that require the consideration of the interaction between several design disciplines. Due to certain organizational aspects of MDO problems, decomposition algorithms are often the only feasible solution approach. Two natural decomposition approaches to the MDO problem are bilevel decomposition algorithms and Sc...
