In this paper, the authors highlight recent accomplishments in the life-cycle performance assessment, maintenance, monitoring, management and optimisation of structural systems under uncertainty, and identify challenges in this area.
Abstract
Our knowledge to model, analyse, design, maintain, monitor, manage, predict and optimise the life-cycle performance of structures and infrastructures under uncertainty is continually growing. However, in many countries, including the United States, the civil infrastructure is no longer within desired levels of performance and safety. Decisions regarding civil infrastructure systems should be supported by an integrated reliability-based life-cycle multi-objective optimisation framework by considering, among other factors, the likelihood of successful performance and the total expected cost accrued over the entire life-cycle. The primary objective of this paper is to highlight recent accomplishments in the life-cycle performance assessment, maintenance, monitoring, management and optimisation of structural systems under uncertainty. Challenges are also identified.

Study and Development of Amalgamating Rules for the Reliability Indicators of Power train System Elements

TL;DR: In terms of assessing reliability, there are two approaches: the combined approach is that the entire mechanical system as a whole is tested or observed, and the classical reliability methods, dominated by mathematical-statistical methods, invariant to the type of failure.

Life-Cycle Assessment of Deteriorating RC Bridges Using Artificial Neural Networks

TL;DR: In this article , the authors proposed an approach to the life-cycle assessment of deteriorating reinforced concrete (RC) bridges based on artificial neural networks (ANNs), which can provide reliable bridge assessments over time under uncertainty on the basis of limited data stored in bridge databases.
