Quantifying the value of information transfer in population-based SHM

no code implementations6 Nov 2023 Aidan J. Hughes, Jack Poole, Nikolaos Dervilis, Paul Gardner, Keith Worden

Population-based structural health monitoring (PBSHM), seeks to address some of the limitations associated with data scarcity that arise in traditional SHM.

Sharing Information Between Machine Tools to Improve Surface Finish Forecasting

no code implementations9 Oct 2023 Daniel R. Clarkson, Lawrence A. Bull, Tina A. Dardeno, Chandula T. Wickramarachchi, Elizabeth J. Cross, Timothy J. Rogers, Keith Worden, Nikolaos Dervilis, Aidan J. Hughes

At present, most surface-quality prediction methods can only perform single-task prediction which results in under-utilised datasets, repetitive work and increased experimental costs.

A decision framework for selecting information-transfer strategies in population-based SHM

no code implementations13 Jul 2023 Aidan J. Hughes, Jack Poole, Nikolaos Dervilis, Paul Gardner, Keith Worden

Decision-support for the operation and maintenance of structures provides significant motivation for the development and implementation of structural health monitoring (SHM) systems.

Towards risk-informed PBSHM: Populations as hierarchical systems

no code implementations13 Mar 2023 Aidan J. Hughes, Paul Gardner, Keith Worden

The current paper presents a formal representation of populations of structures, such that risk-based decision processes may be specified within them.

Decision Making

Mitigating sampling bias in risk-based active learning via an EM algorithm

no code implementations25 Jun 2022 Aidan J. Hughes, Lawrence A. Bull, Paul Gardner, Nikolaos Dervilis, Keith Worden

For SHM applications, the value of information is evaluated with respect to a maintenance decision process, and the data-label querying corresponds to the inspection of a structure to determine its health state.

Active Learning Decision Making

Improving decision-making via risk-based active learning: Probabilistic discriminative classifiers

no code implementations23 Jun 2022 Aidan J. Hughes, Paul Gardner, Lawrence A. Bull, Nikolaos Dervilis, Keith Worden

For risk-based active learning in SHM, the value of information is evaluated with respect to a maintenance decision process, and the data-label querying corresponds to the inspection of a structure to determine its health state.

A probabilistic risk-based decision framework for structural health monitoring

no code implementations5 Jan 2021 Aidan J. Hughes, Robert J. Barthorpe, N. Dervilis, Charles R. Farrar, Keith Worden

Obtaining the ability to make informed decisions regarding the operation and maintenance of structures, provides a major incentive for the implementation of structural health monitoring (SHM) systems.
