Reliability-based optimization of parallel systems

- Summary

Abstract

Systems modelled as a series system of parallel systems are considered and it is shown how the reliability of such systems can be estimated using first order reliability methods (FORM). This type of systems can be used to estimate the reliability of systems in a large number of disciplins, for example structural, economic and electrical systems. In order to estimate the reliability of a parallel system using FORM an optimization problem with quadratic objective function and non-linear constraints has to be solved. An algorithm to solve this optimization problem is presented.
