A strategy for reliability-based optimization
Engineering Structures, 1997Various formulations for reliability-based optimization and the associated problems are discussed. A formulation, in which component and system reliability requirements are balanced, is proposed. A typical frame of a small water plane twin hull (SWATH) ship is optimized by this method.

Reliability-Based Optimization as an Information Tool*
Mechanics of Structures and Machines, 1994ABSTRACT Reliability-based optimization is presented as an information tool in the process of achieving knowledge about the nature of a problem. Sensitivity analysis in pre- and post-evaluation of reliability-based optimization models is introduced for the purpose of identification of important problem parameters.

Reliability-based Design Optimization
2019The solution of reliability-based design optimization problems by using reduced-order models is considered in this chapter. Specifically, problems involving high-dimensional stochastic dynamical systems are analyzed. The design process is formulated in terms of a constrained nonlinear optimization problem, which is solved by a class of interior point ...

A scenario optimization approach to reliability-based design
Reliability Engineering & System Safety, 2020This article introduces a scenario optimization framework for reliability-based design given a set of observations of uncertain parameters. In contrast to traditional methods, scenario optimization makes direct use of the available data thereby eliminating the need for creating a probabilistic model of the uncertainty in the parameters.

Experience with Approximate Reliability-Based Optimization Methods
44th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2003Traditional reliability-based design optimization (RBDO) requires a double loop iteration process. The inner optimization loop is to find the most probable point (MPP) and the outer is the regular optimization loop to optimize the RBDO problem with reliability objectives or constraints.

Reliability-Based Design Optimization of Aeroelastic Structures
9th AIAA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 2002Aeroelastic phenomena are most often either ignored or roughly approximated when uncertainties are considered in the design optimization process of structures subject to aerodynamic loading, affecting the quality of the optimization results. Therefore, a design methodology is proposed that combines reliability-based design optimization and high ...

Reliability-Based Design Optimization
2018As mentioned in earlier chapters, many system failures can be traced back to various difficulties in evaluating and designing complex systems under highly uncertain manufacturing and operational conditions. Our attempt to address this challenge continues with the discussion of reliability-based design optimization (RBDO).

Reliability-Based Design Optimization for Cloud Migration
IEEE Transactions on Services Computing, 2014The on-demand use, high scalability, and low maintainance cost nature of cloud computing have attracted more and more enterprises to migrate their legacy applications to the cloud environment. Although the cloud platform itself promises high reliability, ensuring high quality of service is still one of the major concerns, since the enterprise ...

On Reliability-Based Structural Optimization
1991In this paper a brief presentation of the state-of-the-art of reliability-based structural optimization (RBSO) is given. Special emphasis is put on problems related to application of RBSO on real (large) structures. Shape optimization, knowledge-based optimization and optimal inspection strategies are briefly discussed.

Multi-Objective Reliability-Based Optimization with Stochastic Metamodels
Evolutionary Computation, 2011This paper addresses continuous optimization problems with multiple objectives and parameter uncertainty defined by probability distributions. First, a reliability-based formulation is proposed, defining the nondeterministic Pareto set as the minimal solutions such that user-defined probabilities of nondominance and constraint satisfaction are ...
