Reliability-Based Optimization Using Evolutionary Algorithms [PDF]
IEEE Transactions on Evolutionary Computation, 2009 Uncertainties in design variables and problem parameters are often inevitable and must be considered in an optimization task if reliable optimal solutions are sought. Besides a number of sampling techniques, there exist several mathematical approximations of a solution's reliability. These techniques are coupled in various ways with optimization in the

Robust and reliability-based design optimization of steel beams [PDF]
Archives of Civil Engineering, 2023 In line with the principles of modern design a building structure should not only be safe but also optimized. In deterministic optimization, the uncertainties of the structures are not explicitly taken into account.

Optimal reliability-based code calibration [PDF]
Structural Safety, 1994 Calibration of partial safety factors is considered in general, including classes of structures where no code exists beforehand. The partial safety factors are determined such that the difference between the reliability for the different structures in the class considered and a target reliability level is minimized.
