An Efficient Approach for System Reliability-based Design Optimization

The reliability-based design optimization (RBDO) aims to design structures which should be reliable and economical. The RBDO involves the evaluation of probabilistic constraints, which can be done in two different ways : the reliability index approach (RIA), which describes the probabilistic constraint in terms of reliability index, and the performance measure approach (PMA) where the probabili...

Reliability-Based Multidisciplinary Optimization for Aircraft Wing Design

Aircraft wing design typically involves multiple disciplines such as aerodynamics and structure. Multidisciplinary design optimization (MDO) has been recently used to deal with the multidisciplinary efforts in wing design. When reliability is considered, MDO for the wing design becomes much more computationally intensive. To improve the efficiency, the strategy of using Sequential Optimization ...

Sequential Optimization and Reliability Assessment Method for Efficient Probabilistic Design

Probabilistic optimization design offers tools for making reliable decisions with the consideration of uncertainty associated with design variables/parameters and simulation models. In a probabilistic design, such as reliability-based design and robust design, the design feasibility is formulated probabilistically such that the probability of the constraint satisfaction (reliability) exceeds th...
