Reliability-based process design and optimization
The Proceedings of 2011 9th International Conference on Reliability, Maintainability and Safety, 2011Uncertainty 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.

Reliability-based robust design optimization: A comparative study
2011 IEEE MTT-S International Microwave Workshop Series on Innovative Wireless Power Transmission: Technologies, Systems, and Applications, 2011Reliability-based robust design optimization (RBRDO) is one of the most essential tools developed in recent years to improve the quality and reliability of the products at an early design stage. This paper presents a comparative study of different formulation approaches of RBRDO models and their performances.

Enhancing product robustness in reliability-based design optimization
Reliability Engineering & System Safety, 2015Abstract Different types of uncertainties need to be addressed in a product design optimization process. In this paper, the uncertainties in both product design variables and environmental noise variables are considered. The reliability-based design optimization (RBDO) is integrated with robust product design (RPD) to concurrently reduce the ...

Global Reliability-Based Design Optimization
2004In 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.

A Decision-Analytic Approach to Reliability-Based Design Optimization
Operations Research, 2009Reliability-based design optimization is concerned with designing a product to optimize an objective function, given uncertainties about whether various design constraints will be satisfied. However, the widespread practice of formulating such problems as chance-constrained programs can lead to misleading solutions.

Fuzzy Reliability-Based Optimization for Engineering System Design
International Journal of Fuzzy Systems, 2019Both the performance and the useful life of engineering systems can be affected by uncertainties that have not been considered at the design stage of such systems. Therefore, uncertainty, reliability, and robustness analyses are important tools to evaluate the influence of uncertainties on the operational conditions of machines and structures during ...

Reliability-based design optimization for nonlinear energy harvesters
SPIE Proceedings, 2015This 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.

Reliability-based optimal structural design by the decoupling approach
Reliability Engineering & System Safety, 2001Abstract A decoupling approach for solving optimal structural design problems involving reliability terms in the objective function, the constraint set or both is discussed and extended. The approach employs a reformulation of each problem, in which reliability terms are replaced by deterministic functions.

A collaborative strategy for reliability-based multidisciplinary design optimization
Proceedings of the 2013 IEEE 17th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2013The conventional reliability-based multidisciplinary design optimization (RBMDO) is the direct integration of reliability analysis methods and deterministic multidisciplinary design optimization (DMDO), which always cause the expensive computations. In order to tackle this computational difficulty, an collaborative strategy for RBMDO is proposed.
