Multidisciplinary Design Optimization for the Preliminary Design of Aeronautical Configurations

45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics & Materials Conference, 2004
The paper presents an approach developed primarily by the authors for the integrated modeling of structures, aerodynamics, aeroelasticity and ight mechanics. The motivation for the formulation is MDO/PD (Multi{Disciplinary Optimization for Preliminary Design) for innovative aircraft congurations, and is therefore rst{principle based, since in this case

Collaboration and multidisciplinary design optimization for mechatronic systems

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
The design of mechatronic systems requires the collaboration between different engineers at the disciplinary level and multidisciplinary design optimization (MDO) in the system level. However, the lack of a common knowledge basis between the system and disciplinary levels creates a gap between them.

Collaborative Multidisciplinary Design Optimization

Leadership and Management in Engineering, 2001
Multidisciplinary design optimization (MDO) has been relegated to a process centered about a series of mathematical procedures. Although the early MDO framework of the 1990s was structured, it retained the basic elements of concurrent engineering, which included qualitative as well as quantitative factors.

An Uncertainty Analysis Approach to Multidisciplinary Design Optimization

Concurrent Engineering, 2009
Uncertainty management is an important research issue in multidisciplinary design optimization (MDO), especially at the conceptual design stage. The good uncertainty management can significantly improve the quality of product design. In this research, three types of uncertainties of MDO in conceptual design are analyzed, and a novel systematic approach

A Distributed Collaborative Design Framework for Multidisciplinary Design Optimization

2006
It is traditionally a challenging task to develop a distributed collaborative environment for solving Multidisciplinary Design Optimization (MDO) problem, due to the high degree of heterogeneity of various engineering computer tools and geographically distributed organizations.

Multidisciplinary design optimization under correlated uncertainties

Concurrent Engineering, 2017
Uncertainty analysis is a hot research topic in multidisciplinary design optimization for complex mechanical systems. Existing multidisciplinary design optimization works typically assume that uncertainties are uncorrelated of each other. In real-world engineering systems, however, correlations do exist between different uncertainties.
