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

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 ...

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 process design and optimization

The Proceedings of 2011 9th International Conference on Reliability, Maintainability and Safety, 2011
Uncertainty is inevitable in any manufacturing process. The uncertainty could be due to the variations in geometry of the part, local stress centralization, crack and so on so forth. These defects could be hidden in the part in despite of detection, and finally lead to distortion, break and premature failure.

Global Reliability-Based Design Optimization

2004
In the field of deterministic structural optimization, the designer reduces the structural cost without taking into account uncertainties concerning materials, geometry and loading. This way the resulting optimal design may represent a lower level of reliability and thus a higher risk of failure.

Reliability-based design optimization for nonlinear energy harvesters

SPIE Proceedings, 2015
This paper presents reliability-based design optimization (RBDO) and experimental validation of the purely mechanical nonlinear vibration energy harvester we recently proposed. A bi-stable characteristic was embodied with a pre-stressed curved cantilever substrate on which piezoelectric patches were laminated.

Design Potential Concept for Reliability-Based Design Optimization

Volume 2: 26th Design Automation Conference, 2000
Abstract This paper presents a design potential concept for reliability-based design optimization by integrating the probability analysis into the design optimization process. The reliability-based system parameter design is illustrated by the design potential concept in a unified system space, where design potential surfaces are derived

New Approach for System Reliability-Based Design Optimization

AIAA Journal, 2005
<div class="htmlview paragraph">An efficient approach for Reliability-Based Design Optimization (RBDO) of series systems is presented. A modified formulation of the RBDO problem is employed in which the required reliabilities of the failure modes of a system are design variables.

Reliability Based Design Optimization Using Automatic Differentiation

Volume 9: Transportation Systems; Safety Engineering, Risk Analysis and Reliability Methods; Applied Stochastic Optimization, Uncertainty and Probability, 2011
Typically, a reliability based design optimization (RBDO) problem is solved as a nested optimization problem because an evaluation of the probabilistic constraint(s) involves solving a minimization problem. Over the years, a number of algorithms have been developed to solve the RBDO problem efficiently.
