Project Title:

Uncertainty-based Multidisciplinary

Design Optimization for Aerospace

Structures

Technical Abstract (Limit 200 words)

The proposed effort is concerned with the

development of a multi-disciplinary design

optimization [MDDO] software program. This

software would permit the consideration of

numerous different measures of product

performance as well as reliability in order to

determine the optimal product configuration. The

MDDO software would enable engineers to

consider the impact of design changes on all

relevant measures of performance simultaneously.

The software is innovative for several reasons.

First, it would be the first methodology capable of

handling both measures of product performance and

reliability. Second, it would enable the consideration

of variable uncertainty in the analysis of the

product design. The incorporation of variable

uncertainty would enable the designer to determine

the impact such uncertainty plays in the desired

product performance and reliability. The software

would directly estimate the sensitivity of each

performance measure to each random variable, as

well as the performance sensitivities to random

variable uncertainties. The ability to consider

variable uncertainty in a multi-disciplinary

optimization routine would be unique, and would

represent a significant advance over existing design

software.

Potential Commercial Applications (Limit 200 words)

The proposed software program would permit

multi-disciplinary evaluation of product designs and

include both variable uncertainties, measures of

product performance, and reliability. This software

capability would dramatically improve the

performance and reliability of aviation, aerospace,

and other large complex systems. The capability of

assessing a product design under consideration of

multiple performance measures and reliability is a

significant improvement of existing methods.

Application of the software would be found in any

complex product or component where engineering

expertise has been used to determine the

appropriate trade-off in design and performance.
