Distant Relative Genetic Algorithm–Based Structural Reliability Optimization

STRUCTURAL SYSTEM RELIABILITY-BASED OPTIMIZATION OF TRUSS STRUCTURES USING GENETIC ALGORITHM

Structural reliability theory allows structural engineers to take the random nature of structural parameters into account in the analysis and design of structures. The aim of this research is to develop a logical framework for system reliability analysis of truss structures and simultaneous size and geometry optimization of truss structures subjected to structural system reliability constraint....

Reliability-Based Optimization of structural systems

Effects of population size and relative elitism on optimization speed and reliability of genetic algorithms

A good selection of the internal parameters of a genetic algorithm may reduce the optimization speed considerably. We studied the effects of two key parameters, namely population size and relative elitism, on the optimization speed and reliability. We found that changing one parameter can be compensated for changing another. By penalizing for the unreliability of the genetic algorithm the optim...

STRUCTURAL OPTIMIZATION USING A MUTATION-BASED GENETIC ALGORITHM

The present study is an attempt to propose a mutation-based real-coded genetic algorithm (MBRCGA) for sizing and layout optimization of planar and spatial truss structures. The Gaussian mutation operator is used to create the reproduction operators. An adaptive tournament selection mechanism in combination with adaptive Gaussian mutation operators are proposed to achieve an effective search in ...

Genetic Optimization of Multidimensional Technological Process Reliability

A technological process (TP) is considered multidimensional if a number of defects of diverse types occur, and they are detected and corrected simultaneously within the process execution [4, 5]. Quality of the TP is estimated by the probability of output zero-defects as well as by the probabilities of zero-defects for each of the defect types. The tasks of TP-optimization involve the choice of ...
