Reliability-Based Design Optimization

2018
As mentioned in earlier chapters, many system failures can be traced back to various difficulties in evaluating and designing complex systems under highly uncertain manufacturing and operational conditions. Our attempt to address this challenge continues with the discussion of reliability-based design optimization (RBDO).

Reliability-Based Design Optimization Methods

Volume 1: 30th Design Automation Conference, 2004
Reliability-based design optimization (RBDO) methods are optimization algorithms that utilize reliability methods to evaluate probabilistic constraints and/or objective functions used to prescribe reliability. For practical applications, it is important that RBDO methods are efficient, i.e, they only require a manageable number of numerical evaluations

Interactive reliability-based structural optimization

Computers & Structures, 1984
Abstract In the field of structural optimization the interactive computer-aided design (CAD) system becomes central as a tool for searching and evaluating alternatives to obtain the best design among given choices. Along these lines, this paper presents a new interactive reliability-based CAD optimization procedure for plastic framed structures. Both

Reliability-Based Optimization Using SFEM

1991
The problem of reliability-based optimum design of realistic structures requires the resolution of several issues, some of which are as follows. (i) Most practical structures have complicated configurations, and their analysis has to be done using computer-based numerical procedures such as finite element analysis; for such structures, the response is ...

Reliability-Based Design Optimization of Aeroelastic Structures

9th AIAA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 2002
Aeroelastic phenomena are most often either ignored or roughly approximated when uncertainties are considered in the design optimization process of structures subject to aerodynamic loading, affecting the quality of the optimization results. Therefore, a design methodology is proposed that combines reliability-based design optimization and high ...
