Structural Reliability Optimization
1994Maximum likelihood points play a predominant role in structural reliability computation. The point of maximum likelihood (or the failure point) is the solution of a nonlinear mathematical programming problem with a nonlinear equality constraint (NEP). Sequential quadratic programming (SQP) is regarded as one of the best procedures to solve an NEP1, 2 ...

Optimization of Systems Reliability
IEEE Transactions on Reliability, 1967The purpose of this paper is to obtain an optimum redundancy of the parallel system by a variational technique. The objective function is to maximize the system profit. A simple computational procedure is obtained for the optimum design of the multistage parallel systems by this method. Two numerical examples are given in detail.

The sequential optimization and reliability assessment (SORA), which is a decoupled reliability-based design optimization (RBDO) method, is generally more efficient than conventional double-loop RBDO methods but less efficient than single-loop approaches because of the most probable point (MPP) search in the reliability assessment loop of SORA.

Reliability Optimization using SLUMT
IEEE Transactions on Reliability, 1975This paper is concerned with the reliability optimization of a spatially redundant system, subject to various constraints, by using nonlinear programming. The constrained optimization problem is converted into a sequence of unconstrained optimization problems by using a penalty function.

Bayesian Optimal Designs for Reliability
In this paper, we attempt to improve the use of optimal designs for the technological field by applying Markov Chain Monte Carlo simulations, and by evaluating: i) a hierarchical structure of the observed data; ii) the definition of a specific utility function; iii) model discrim- ination by the predicting point of view.Rossella Berni +2 more

Computer Reliability Optimization System
IEEE Transactions on Reliability, 1971The short electronic system development time, the acute competitiveness, the emphasis on lower costs, and the insistence upon high reliability has fostered practical computerization of the manager's and designer's reliability function. This computerization attempts to achieve feasible system optimization.

Reliability-Based Optimization and Optimal Reliability Level of Offshore Wind Turbines
2005Different formulations relevant for the reliability-based optimization of offshore wind turbines are presented, including different reconstruction policies in case of failure. Illustrative examples are presented and, as a part of the results, optimal reliability levels for the different failure modes are obtained as annual probabilities in the interval

BIOGEOGRAPHY-BASED RELIABILITY OPTIMIZATION
Biogeography-based optimization (BBO) is an effective optimization algorithm originally introduced by Dan Simon in 2008. It is inspired by the principles of biogeography. It mimics the process of migration and colonization of different species, where the behavior of species is determined by their habitats and the available resources.Garg, Deepika +3 more
